    Why 'The Smashing Machine' works as a film (not just an MMA movie)

    1. NA

      (drumbeats) Joe Rogan podcast, check it out. The Joe Rogan Experience. (drumbeats)

    2. JR

      Train by day, Joe Rogan podcast by night, all day. (rock music) Good. Mark, what's happening?

    3. MK

      Joe.

    4. JR

      Dude, the movie's fantastic. And I, and I know I told you outside, but I wanted to save it. Uh, when I kind of have a, had a little bit of a prejudice when I went to see the movie. I was like, "Okay, it's gonna be an MMA movie."

    5. MK

      Yeah.

    6. NA

      Yeah.

    7. JR

      But it's not. It's a movie that happens to be about MMA, but it's a great movie.

    8. MK

      Oh, I appreciate that.

    9. JR

      It's, it's really good, man. It's, it's like, you know, it's v- very gripping, and the performances are fantastic, and the way The Rock did you was nuts.

    10. MK

      I, like, I can't explain it. Uh, it, I, I keep using the word surreal, but it doesn't describe it. Um, like I was saying that, uh, my son, when he watched it, and just flipping out, like, talking to me, like on the side, like I was saying, like literally just going, "Dad, Dad, he's got your mannerisms."

    11. NA

      (laughs)

    12. MK

      "He's got your speech manner." But if you imagine, like I'm, I'm picturing my son, he's in New York when he watched it. Like-

    13. JR

      Right.

    14. MK

      Uh, and so I'm picturing him in the corner of the lobby of the theater, talking with his back to everybody going, "Oh my God, Dad, like, it's like a doppelganger."

    15. NA

      (laughs)

    16. MK

      "He's got all of it." You know, like full-blown, like, it was like the, the, the, 'cause a lot of my saying for myself is I'm, uh, I can't see the forest through the trees. I'm in the middle of it. Am I looking at it objectively? Am I really looking at it, or am I seeing something? And to hear my son say, "Oh my gosh, Dad, he nailed it."

    17. JR

      Right. No, he-

    18. MK

      Unbelievable.

    19. JR

      He really did nail it. I, like we were saying in the lobby, like, I didn't know The Rock could act that well.

    20. MK

      You know-

    21. JR

      But it's really good acting. It's not like blockbuster movie acting, which is, he's great at that, but-

    22. MK

      Yep.

    23. JR

      ... it's, it's a different thing.

    24. MK

      It, it, it's compl- it, so with DJ, I kept trying to say to him, "You don't have to do this, dude. Like, you don't have to do this." And he would, he would stop me and he would go, "Yeah, I do. I do."

    25. JR

      What do you mean by you don't have to do this? You don't have to, like-

    26. MK

      So meaning that, like, he's at a, he's at-

    27. JR

      ... totally beat me?

    28. MK

      He's at a place in his life where he can just keep doing blockbusters and be perfectly fine with it.

    29. JR

      Mm-hmm.

    30. MK

      There's, there is, uh, uh, I mean, he says it himself, there's always a place for that. There's always gonna be a place for blockbuster movies, and, and for that. But he needed to do something different.

  2. 3:214:47

    Watching your life on screen: Venice premiere as therapy and self-reckoning

    1. MK

      So here's... So here's what was even... So it ve- so I saw a, uh, an 80% complete version of the film in, in January of this year, and then, um, and then the first time I see a complete version of it was in Venice. And so I'm in Venice, and there's Benny on my right, and there's DJ on my left, and there's Emily next to, uh, DJ. In the last scene of the movie, right? That intensity of that scene, I- I'm just telling you, it was like, uh, I, I said it was therapy for me.

    2. JR

      Mm.

    3. MK

      'Cause I think for the first time, I could actually, I could actually see my f- part in it. Like, I could see my part how fucking hard I was on the people around me. You know, how just singularly driven I was to accomplish something at, at all cost. And the person that paid it the most was Dawn. She paid a heavy price, you know? And you know anybody that's successful, you know, for me, I was trying to raise everybody up, you know, everybody around me. And it was just this selfish endeavor, and I could see it in those moments. I could see it in what, who DJ was, uh, you know, and who Emily was, and the intensity of that is like, "Fuck."

    4. JR

      Well, it's such a crazy task to try to be an elite MMA fighter at a time where th- there was no, no one even knew what it was.

    5. MK

      No. Mm-mm.

  3. 4:476:40

    Early UFC era and the birth of MMA: Joe’s 1997 memories and the “best style” question

    1. JR

      I mean, you, when you, first, uh, when I met you in '97, there's a crazy photo of us together.

    2. MK

      Yeah, I saw that. (laughs)

    3. JR

      Dude, '97, that's like 30 years ago almost. Isn't that nuts?

    4. MK

      It's g- so this is what's fucking crazy. So trying to describe what I did back then, like people, w- their jaws would hang open.

    5. JR

      Right.

    6. MK

      They would go, "You do what?"

    7. JR

      Like, why would you do that? That's awesome.

    8. MK

      Yeah.

    9. JR

      Look at that. (laughs)

    10. MK

      Oh my God. (laughs)

    11. JR

      1997, dude. That's so crazy.

    12. MK

      Oh my God.

    13. JR

      So crazy.

    14. MK

      Oh my God.

    15. JR

      So much time ago.

    16. MK

      Were they even paying you back then?

    17. JR

      A little bit. They paid me a little bit.

    18. MK

      Oh my God.

    19. JR

      Uh, it wasn't a lot of money, but it was, for me, it was just for fun. It was like, uh, I was a f- giant fan of the sport, and what happened was, Campbell McLaren, do you remember Campbell?

    20. MK

      Yeah, yeah.

    21. JR

      Um-

    22. MK

      Yeah.

    23. JR

      ... he, he was good friends with my manager, Jeff, and, uh, they were just talking, and he said, "Uh, we need a guy to do backstage interviews, uh, post-fight interviews."

    24. MK

      Yes.

    25. JR

      And he goes, "Joe really loves this sport." He's like, "Really?" He goes like, "Oh yeah, he follows all the fights in Japan."

    26. MK

      Oh my God.

    27. JR

      "And he's like..." And so for me, it was just fun. I mean, it wa- it wasn't, it was actually costing me money, which is why I wound up quitting.

    28. MK

      (laughs)

    29. JR

      Because I quit, and I did it for like a year and a half, two years maybe.And then in '98, I was like, "I can't do this anymore. I'm just ... It's just actually costing me money." And so then, when I, um, started doing Fear Factor, that's when Zuffa bought it-

    30. MK

      Yeah.

  4. 6:409:59

    Why wrestling rules MMA: control, pace, cardio, and sustained attacks

    1. MK

      That was ... So part of my first fights in Brazil, I was still, uh, brainwashed by the idea that, "Oh, shit, he's seven foot tall or 6'9", he's the toughest dude in the room."

    2. JR

      Right.

    3. MK

      'Cause y- 'cause y- I- 'cause that's how I grew up, right?

    4. JR

      Right.

    5. MK

      Or ten-degree black belt, same thing.

    6. JR

      Right, right, right.

    7. MK

      "Oh, no, no, (laughs) no. Don't mess with him."

    8. JR

      Yeah.

    9. MK

      And in one where, where that first time I fought, I was still under the delusion that that was the truth.

    10. JR

      Mm-hmm.

    11. MK

      And so my trainer kept going, "Oh, trust me, you're gonna, you're gonna do fine. Trust me, you're gonna do fine." (laughs) And it's just like, he understood what, what, what I was as a wrestler-

    12. JR

      Mm-hmm.

    13. MK

      ... you know, that I can impose ... Like, this is to tell you, the def- best definition I've ever had for a wrestler is, I can hold a grown-ass man where he doesn't wanna be held for as long as I wanna hold him there, and he can't do a fucking thing about it.

    14. JR

      Exactly.

    15. MK

      That's a wrestler.

    16. JR

      And you can dictate where the fight-

    17. MK

      Yep.

    18. JR

      ... takes place, always. So if you become a wrestler like Chuck Liddell-

    19. MK

      Yep.

    20. JR

      ... then you say, "No, no, no, you can't take me down."

    21. MK

      Mm-hmm.

    22. JR

      "So I'm just gonna beat the fuck outta you-

    23. MK

      Yep.

    24. JR

      ... standing, and there's nothing you can do about it."

    25. MK

      Not, not a single thing.

    26. JR

      Yeah. It's the most important skill.

    27. MK

      Oh my God, it's foundational-

    28. JR

      Foundational.

    29. MK

      ... and, and that's why there's so much suc- success for, for the d- um ... I g- I'm gonna blank on the names, but, uh, the, the wrestlers are ... It's a resurgence of, like, really what a foundational piece it is-

    30. JR

      Yeah.

  5. 9:5915:21

    Steroids, PRIDE culture, and the wild west of contracts and “drug testing”

    1. JR

      Well, I remember when you came along and when Coleman came along. All of a sudden, everybody's like, "I gotta get on steroids." (laughs)

    2. MK

      Yeah. Oh my God, yeah.

    3. JR

      But it's like, "I gotta get bigger."

    4. MK

      (laughs)

    5. JR

      "I gotta get bigger."

    6. MK

      Yeah.

    7. JR

      That's when Vitor got up to, like, 240 pounds.

    8. MK

      Oh my God, he was big. He was big.

    9. JR

      He got way too big for his frame. I mean, you're talking about a guy who eventually wound up fighting at 185.

    10. MK

      Yeah.

    11. JR

      Right?

    12. MK

      Yeah.

    13. JR

      I mean, he finished his career up at 85, and he was there at 240 when he fought Randy the first time-

    14. MK

      Yeah.

    15. JR

      ... which was bananas.

    16. MK

      So that night was my last UFC. That was UFC 15.

    17. JR

      Oh, wow.

    18. MK

      And that's when Randy beat Vitor.

    19. JR

      Mm-hmm.

    20. MK

      And it was one of those where I'm like, "Oh, just wait." I kn- it's 'cause I know what Randy is.

    21. JR

      Right.

    22. MK

      Randy's cardio.

    23. JR

      Mm-hmm.

    24. MK

      Randy-o's like, he can take it, and he ... It was one of those things where I was like, "I don't think Victor's gonna win."

    25. JR

      Right.

    26. MK

      It's just that-

    27. JR

      And that's what we called him-

    28. MK

      ... it's styles.

    29. JR

      ... back then. His name was Victor.

    30. MK

      Yeah, Victor.

  6. 15:2137:29

    Authenticity obsession: rebuilding 1990s MMA sets, props, and PRIDE weirdness

    1. MK

      Yo, uh, i- so, you know, that was a huge part from the beginning of this when, when DJ and I, DJ and I talked back in 2019, is just the, like, the trust factor.

    2. JR

      You guys started talking about this in 2019?

    3. MK

      Yeah, in 2019, yeah.

    4. JR

      Wow.

    5. MK

      Yeah.

    6. JR

      Six fucking years.

    7. MK

      Yeah. Yeah.

    8. JR

      Wow.

    9. MK

      Here's what's crazy. So, so he says, "Hey, you know, we're gonna move forward with this." And, and m- I, so for me, I hadn't even thought about any of this. Like, it being a movie, it, he wants to play me in a movie, and he goes, "I'm gonna make the announcement, Madison Square Garden at the BMF Belt." He goes, this, we had this beautiful conversation, and it was just like this, "Do you trust me?" And it was like, "Yeah. Yeah, I do."

    10. JR

      He's a fucking great dude.

    11. MK

      Oh, my God, solid, he's... By the way, he says, "Say hi." He left me a great message on the way over here. (laughs) I was listening to him, man. He's just, he's, he's a rare human being.

    12. JR

      He is. I'm gonna, I'm gonna call him after this just to tell him what a fucking amazing job he did, 'cause I, well, I wanted to watch it right before I saw you.

    13. MK

      Okay.

    14. JR

      So I watched it today, and I was like, "God damn, this is a good movie, man." And I just, I was just blown away by how well he captured the chaos of the Pride organization, all the, the weirdness of the contract negotiations, everything.

    15. MK

      Off, uh, so, so Benny from the beginning said, "The only way we're gonna be able to do this is have that authenticity," to the point where I sent them watches, rings, necklaces, posters, everything I could find picture-wise, everything, to their props and production.

    16. JR

      Oh, wow.

    17. MK

      And they reproduced everything.

    18. JR

      Oh, wow.

    19. MK

      So, Joe, and when I'm, w- I mean, like, when I went up to Vancouver, like, and walked into some of these sets, like, literally going, "Holy fucking shit, man."

    20. JR

      (laughs) Did it flash back?

    21. MK

      Oh, my God, like, like, you'd walk into a room and there'd, there'd be from one corner all the way to the other on the wall just pictures of me in my house, in my this, and this outfit, and this, and these in my house, and this, and, and then production saying, "Okay, was this accurate? How did this..." It was this, it was this unbelievable, painstaking... They rebuilt my life 25 years ago.

    22. JR

      Wow.

    23. MK

      So when DJ got into charac- got into me, he actually was, that was... He was me.

    24. JR

      Wow.

    25. MK

      Yeah.

    26. JR

      It seemed like it, man. I mean, it really did because, you know, it's just, it- it's hard when a guy's so famous to pretend that he's someone else.

    27. MK

      Yeah.

    28. JR

      He has to-

    29. MK

      Yeah.

    30. JR

      ... like, be really good to get you convinced, and I was all in. I was all in.

  7. 37:2941:14

    PRIDE vs UFC: Kerr’s contract dispute, almost fighting Royce Gracie, and Japan’s hidden operators

    1. JR

      So what was, what was the Pride experience like? So you, you had fought in the UFC, and then did, did you have a contract that expired? Like, what happened?

    2. MK

      So, oh boy, this is the... So, I signed a three-fight tournament deal with the UFC. I did '14 and '15, and I still had one, uh, tournament obligation on the contract. Um, so after '15, the Japanese had seen enough footage, and I got contacted by Pride. And they're like, "Hey, we wanna fly you over. We want to, um, we wanna have, uh, you as a key piece to build this organization." So I'm like, "Okay." So they fly me first class over, first class hotel. I meet with, um, I meet with a guy named Mr. Ishizaka, who, uh, his real name is Kim Duk Soo. He's a Korean guy. And, uh, the, um, Mr. Ishii, who owned K-1...

    3. JR

      Wait a minute. A Korean dude was pretending to be Japanese?

    4. MK

      You had to have a Japanese name.

    5. JR

      Whoa.

    6. MK

      You couldn't do business in Japan without a Japanese name.

    7. JR

      That's crazy. So he just changed his name?

    8. MK

      He signed all of his documents, signed all of his documents, legal documents, Kim Duk Soo.

    9. JR

      Wow.

    10. MK

      But every single person called him Mr. Ishizaka.

    11. JR

      Wow.

    12. MK

      Yeah.

    13. JR

      So he had to learn Japan- Japanese, he had to-

    14. MK

      Yeah. And it's still with an accent 'cause he spoke Korean too.

    15. JR

      Ah. (laughs)

    16. MK

      So it's just one of those (Joe laughs) where understanding, like, the, the culture back then just-

    17. JR

      Wow.

    18. MK

      ... it was still stuck, you know, and hadn't really progressed.

    19. JR

      Wow.

    20. MK

      Um, so Mr. Ishii owned K-1, and Mr. Ishizaka started Pride. And it was called KRS at the beginning, before turning into Dream Stage.

    21. JR

      Oh.

    22. MK

      And so here's, here's where it gets a little sticky. So, um, I go over there. I take, uh... For Pride 2, it's supposed to be me and Royce Gracie. Him and I... Uh, there's still fight posters that I've signed of him and I facing off with each other, signed the contract to fight for way more money than was being probably paid for the, uh, in the UFC. And, um, when I get back to the States, I get served with, uh, I get served with papers to appear in court in New York City, the UFC suing me. Um, it's when Bob Meyerwitz still owned it-

    23. JR

      Hmm.

    24. MK

      ... and Art Davis was involved. And so they were suing me for breach of contract. And it was, like, one of those things where I was like, "Okay. I didn't..." You know, like, one of those experiences where I was like, "Oh, shit." You know, and the Japanese said, "Okay, we still want you. You need to sort this out." So it took, uh, it took four months, five months to sort out the differences between what the UFC needed and if they were gonna let me go and all this other stuff. In that timeframe, Royce got hurt. And so Royce had to step out, and they put, uh, Branko Cigic in there, and I ended up fighting Branko in Pride 2.

    25. JR

      Oh, wow.

    26. MK

      Yeah. So if everything, if, if everything would've went as everything, I would've fought Royce Gracie in the Tokyo Dome.

    27. JR

      (exhales)

    28. MK

      Him in a main event, me at-

    29. JR

      Wow.

    30. MK

      ... my peak, Royce still in his prime.

    Heavyweight realities: weight, overtraining, nerves, and the Fujita hypoglycemic crash

    1. JR

      What were you at your heaviest?

    2. MK

      280, 285.

    3. JR

      Geez.

    4. MK

      Like, 6% body fat.

    5. JR

      Whoa.

    6. MK

      Yeah.

    7. JR

      That's hard to breathe. (laughs)

    8. MK

      Oh, it's brutal. Like if I didn't-

    9. JR

      Do you get so much muscle?

    10. MK

      If I didn't fucking get ahold of you-

    11. JR

      Right.

    12. MK

      ... and fucking squeeze the life out of you in the first, like, couple minutes-

    13. JR

      Yeah.

    14. MK

      ... I was fucked. I was completely fucked, you know.

    15. JR

      Yeah. Well, that was kinda the case with Coleman as well, like when-

    16. MK

      Yeah.

    17. JR

      ... when he was really, really big.

    18. MK

      I was in the corner-

    19. JR

      Battling the hell.

    20. MK

      ... when he lost... When, I was cornering him when he lost to Maurice Smith.

    21. JR

      Oh, okay. Yeah. Yeah. I was there for that one.

    22. MK

      Yeah.

    23. JR

      That was, that was, uh, a real game-changer.

    24. MK

      Oh, that changed the narrative for everything.

    25. JR

      'Cause Maurice, what Maurice brought to the game was... Maurice was training with Frank Shamrock at the time.

    26. MK

      Yep.

    27. JR

      And so he had extreme cardio. He was doing a lot of swimming, he was running hills.

    28. MK

      Yep.

    29. JR

      I mean, he was really cardiovascularily at an elite level for an MMA-

    30. MK

      Yep.

    MMA’s modern leap: technique explosion, GOAT debates, and the “new gear” phenomenon

    1. JR

      It's just... It's such a crazy sport to watch that, you know, from 1994 to 2025, it's almost unrecognizable, the difference in the gap.

    2. MK

      You can't, you can't. Like, like there was a period of time where I couldn't, I couldn't watch, uh, I didn't watch the UFC probably about like seven, eight, nine years. And, uh, over the last five, six years I've watched it, uh, almost religiously, right? And just realizing the fighters today, oh my God, man, they're, they hit a level and it's that, it's that mutation. It's like this first generation-

    3. JR

      Mm-hmm.

    4. MK

      ... second generation.

    5. JR

      Mm-hmm. Yes.

    6. MK

      And they're advancing so fast that you're looking at these new fight... You're like, where... Like, it's such a unique set of skills to do this.

    7. JR

      Mm-hmm.

    8. MK

      Incredible set of skills, unique to any other sport in the world.

    9. JR

      And it's j- and it's also you're really fighting three different sports as one sport.

    10. MK

      Yeah. Yeah.

    11. JR

      Which is really nuts. You're fighting grappling, you're fighting jujitsu-

    12. MK

      Jujitsu and striking.

    13. JR

      ... and you're fighting striking all together.

    14. MK

      Yeah. And-

    15. JR

      In one sport.

    16. MK

      Yeah.

    17. JR

      And it's like, wow.

    18. MK

      It's like playing soccer, football-

    19. JR

      Yeah.

    20. MK

      ... and baseball at the same time. (laughs) It's like, how the fuck would you do that?

    21. JR

      Yeah, while getting kicked.

    22. MK

      While getting kicked. (laughs)

    23. JR

      While getting kicked and punched and elbowed. It's is, uh... But without guys like you, it would have never gotten here because if there weren't people that were willing to fight for very little money, travel overseas, have these crazy events and, you know, and beat your body up and do what you did and what Coleman did and a lot of those guys did in the beginning, without you guys, there's-

    24. MK

      Oh, I appreciate that.

    25. JR

      There is no UFC today.

    26. MK

      Yeah.

    27. JR

      It's just not, it's not the same.

    28. MK

      It was, you know, one... Like being in the Hall of Fame and being in the Pioneer Wing and understanding that, um... Like I said to myself, you know, even if I advance the sport, you know, this much, it needed this much at the time to get to where it is today, right?

    29. JR

      Mm-hmm.

    30. MK

      Like Coleman advanced the sport this much.

    Money, careers, and building fighters: PRIDE paydays, cash briefcases, and UFC’s growth pains

    1. JR

      I know some shit about fighting. But to me, it was like... It was, uh, Eddie Bravo and I, when we were kids, when we were young, young fellas, when we, we were hanging around, working out, we would said to ourselves, like, "You know what this sport needs? Some crazy billionaires who love the sport that're just gonna dump a bunch of money." 'Cause we knew at the time, we were like, "This is the most ex- exciting sport in the world, right?"

    2. MK

      Yeah, yeah.

    3. JR

      So, all it needs is for these really rich guys to be fans of the sport. And it's almost like it manifested itself, 'cause that's what happened. The Fertittas came along-

    4. MK

      Yeah.

    5. JR

      ... and they were just really rich guys who loved the sport, and they took a crazy chance.

    6. MK

      Yeah.

    7. JR

      They were $40 million in the hole.

    8. MK

      In debt, yeah. Oh my God.

    9. JR

      $40 million in the hole on the UFC, and it was just losing money, losing money. And they just hung in there, year after year-

    10. MK

      God.

    11. JR

      ... after year, until they were almost ready to fucking sell, and then they decided to go forward with The Ultimate Fighter.

    12. MK

      That's the game changer.

    13. JR

      That was it.

    14. MK

      That person-

    15. JR

      2005.

    16. MK

      That personalized it.

    17. JR

      Yes, but-

    18. MK

      That, that personalized it.

    19. JR

      Well, people got to see it on Spike TV, and then it became... The fights were so wild that people were calling their friends-

    20. MK

      Yeah.

    21. JR

      ... and they were saying, "You gotta watch this." So as the, the show is on... And this is, like, before social media-

    22. MK

      Yeah.

    23. JR

      ... was really a thing.

    24. MK

      All that, yeah, yeah.

    25. JR

      So as the fight was on, the, uh, the ratings kept going up and up and up and up, and it would... Like, Spike TV was like, "Holy shit-"

    26. MK

      Shit, they're onto something.

    27. JR

      "... we got a fucking hit."

    28. MK

      Yeah.

    29. JR

      "We got a hit."

    30. MK

      Yeah.
