MMA Star Mark Kerr: Dwayne Johnson’s 7 Shocking Transformation Secrets

Mark Kerr: Dwayne Johnson Looks Like He Got Hit By a Truck—And Fans Are Here For It

Let’s cut to the chase: Dwayne “The Rock” Johnson—the guy who once made elbow pads look cool in The Scorpion King—is now sporting hair. Not just any hair, though. We’re talking a greasy, ’90s-era mop that makes him look like he’s been binge-watching Fight Club while chugging protein shakes. The internet is losing its collective mind over his latest role as MMA legend Mark Kerr in The Smashing Machine, and honestly? We’re right there with them.

A24, the studio behind weird-but-brilliant films like Everything Everywhere All At Once, dropped a first-look photo of Johnson as Kerr, and fans immediately started asking, “Wait, is that actually The Rock?” Spoiler: It is. The man’s 6’5” frame is still there, but the bald head, biceps the size of watermelons, and that trademark eyebrow raise? Gone. Replaced by a shaggy haircut, a haunted stare, and the vibe of someone who’s seen too many cage fights.

Let’s unpack why this might be Johnson’s most unhinged (and exciting) career move yet.

Who the Heck Is Mark Kerr—And Why Should You Care?

Before we dive into Johnson’s makeover, let’s talk about Mark Kerr. If you’re not an MMA junkie, here’s the TL;DR: Kerr was a beast in the late ’90s/early 2000s MMA scene. Nicknamed “The Smashing Machine” (hence the film’s title), he dominated with a mix of wrestling chops and sheer aggression. But his career was a rollercoaster of steroids, addiction, and personal chaos—basically, the kind of story A24 loves to turn into an Oscar bait biopic.

Kerr’s life was already documented in a 2002 HBO film of the same name, which showed his struggles with painkiller addiction and a turbulent marriage. Now, Johnson and Emily Blunt (playing Kerr’s wife, Dawn Staples) are diving into the gritty details. Think The Wrestler meets Requiem for a Dream, but with more sweat and fewer bald caps.

The Smashing Machine: Because Normal Movies Are For Cowards

Director Benny Safdie (of Uncut Gems fame) is helming this project, which means two things:

  1. The film will be stressful to watch.

  2. It’ll probably be amazing.

Safdie’s known for chaotic, anxiety-inducing storytelling, and Johnson’s clearly ready to embrace the mess. In a chat with Variety, Johnson said Safdie pushes him to explore “stories that are raw and real, characters that are authentic and at times uncomfortable.” Translation: Don’t expect any Jumanji-style one-liners here. This is Johnson’s “I’m a Serious Actor Now” era, and we’re oddly into it.

Emily Blunt, meanwhile, is playing Dawn Staples—Kerr’s wife, who stuck by him through his darkest moments. Blunt’s fresh off her Oscar-nominated turn in Oppenheimer, so she’s clearly in “I’ll ruin your emotions” mode. Together, Johnson and Blunt might just be the duo we never knew we needed.

Dwayne’s Glow-Down: From Red Carpets to Greasy Hair

Let’s address the elephant in the room: Johnson’s transformation. The man usually looks like he’s seconds away from hosting a Baywatch reboot, but here? He’s channeling “washed-up gym teacher who still thinks nu-metal is cool.” The first-look photo shows him with unkempt hair, a scruffy beard, and a thousand-yard stare that screams, “I haven’t slept since 1997.”

Fans are obsessed. Instagram comments range from “Give him the Oscar NOW” to “Wait, is this AI?” (Spoiler: No, but if it were, we’d demand a refund for Black Adam.) Even Johnson’s wife, Lauren Hashian, commented, “So proud of you,” which roughly translates to, “Thank god you’re not making Tooth Fairy 2.”

7 Deadly Mistakes Dwayne Johnson Avoided (And 3 He Might’ve Made)

Before you start thinking this is just another celebrity vanity project, let’s roast the common pitfalls Johnson sidestepped—and a few he might’ve tripped into.

  1. Mistake: Casting a Muscley Guy to Play a Muscley Guy
    Avoided? Yes.
    Sure, Johnson’s built like a fridge, but Kerr was a different kind of monster—thicker, rougher, and less “polished Hollywood hero.” Props to Johnson for ditching the usual charm and leaning into Kerr’s raw physicality.

  2. Mistake: Making a MMA Movie with No Blood
    Avoided? Probably.
    This is A24. If there’s not at least one scene where Johnson headbutts a wall, we’ll riot.

  3. Mistake: Letting The Rock Play The Rock
    Avoided? Thank god.
    No eyebrow raises. No catchphrases. Just pain, regret, and maybe a broken nose.

  4. Mistake: Forgetting the ’90s Aesthetic
    Avoided? Nailed it.
    The grunge haircut, the baggy shirts—Johnson’s serving “guy who still owns a Blockbuster card.”

  5. Mistake: Skipping the Dark Stuff
    Avoided? TBD.
    Kerr’s story isn’t pretty. If this film glosses over his addiction struggles, we’ll… write a strongly worded tweet.

  6. Mistake: Casting a Random as His Wife
    Avoided? Emily Blunt exists.
    Blunt could read a phone book and make it heartbreaking. Safe bet she’ll crush this.

  7. Mistake: No Training Montage
    Avoided? We hope not.
    Look, we need at least one scene of Johnson grunting while lifting a tractor. It’s the law.

…And 3 Mistakes He Might’ve Made:

  • Too Much Hair Gel: That greasy mop better not distract from the acting.

  • MMA Fans Rage-Quitting: If the fight scenes aren’t brutal enough, Kerr’s old fans will revolt.

  • The Rock’s Ego: Can Johnson disappear into a role, or will we still see “Dwayne” peeking through?

“But Wait, What About the Cake?!”: Dwayne’s Dad Life

While prepping for this role, Johnson still found time to be a grade-A dad. His youngest daughter, Tiana, turned seven, and he nearly caused a cake apocalypse during her birthday party. In a viral Instagram video, he’s seen heroically saving her cake mid-slide off the table, quipping, “You know I’m not letting a bunch of little girls grow up telling a story about how ‘The Rock killed our birthday cake.’”

Priorities, people.

Simone Johnson: The Next Rock? (But Make It WWE)

Johnson’s eldest daughter, Simone, is already carving her own path in WWE—a.k.a. the family business. At 22, she’s the youngest signee in WWE history, and she credits her grandma (not Dwayne) for sparking her passion. “We’d watch old WWE DVDs at her house,” Simone said in an interview. So, if you’re keeping score: Grandma > The Rock.

Already did. She’s wrestling under the ring name “Ava Raine.”

7. What’s next for Dwayne?
After this? Maybe Moana 2—or a nap.

Final Take: Why This Might Be Johnson’s Best Role Yet

Love him or hate him, Johnson’s swinging for the fences here. The Smashing Machine isn’t just another action flick—it’s a raw, unfiltered dive into a flawed man’s life. And if the first photo is any indication, Johnson’s ready to prove he’s more than just muscles and quips.

So mark your calendars for October 2025, and in the meantime, join us in praying that A24 releases a blooper reel of Johnson trying to act with hair.

Inside Joke Alert:
And if you’re wondering—no, this isn’t the first time Dwayne’s been confused with an inanimate object. Remember when CNN accidentally referred to him as “The Boulder” during a 2018 segment? We’re still recovering.
