Dwayne Johnson, is that you? See his dramatic new look as UFC fighter Mark Kerr in ‘The Smashing Machine’ trailer

Dwayne Johnson is stepping into what may be the most transformative role of his acting career, taking on the part of legendary UFC and MMA fighter Mark Kerr in the upcoming film “The Smashing Machine.” This gritty biographical drama, set to release on October 3 and directed by Benny Safdie, offers a deep dive into the life of Kerr—an athlete whose raw physical power in the ring was matched only by the personal demons he battled outside of it. Known widely for his blockbuster action roles, Johnson’s portrayal here marks a significant and deliberate shift toward more dramatic, character-driven storytelling.

In the newly released trailer, Johnson is almost unrecognizable. Though he hasn’t publicly addressed his physical transformation in great detail, it’s apparent that facial prosthetics and careful styling have helped him bear a striking resemblance to Kerr. The fighter’s story, originally featured in the 2002 HBO documentary also titled “The Smashing Machine,” captured the brutal realities of early MMA competition and revealed Kerr’s struggles with substance abuse and emotional turmoil. Johnson appears to embrace every layer of this complexity, channeling the vulnerability and intensity that defined Kerr’s life both inside and outside the ring.

The trailer provides glimpses of the brutal, adrenaline-charged world of professional fighting—raw and visceral in its execution—but it also reveals a far more intimate narrative. Central to this is Kerr’s relationship with his girlfriend, played by Emily Blunt. Reuniting with Johnson after their time together in Disney’s “Jungle Cruise,” Blunt brings a grounded emotional presence to the film. The tension between their characters, caught between love, ambition, and addiction, adds an essential human depth to the story.

In one poignant moment in the trailer, Johnson’s Kerr reflects on the intoxication of success, saying, “Winning is the best feeling in the world. It’s 40,000 people in there cheering you on. There’s no other high like it in the world.” This line encapsulates the highs and lows Kerr experiences as he navigates fame, pain, and a relentless pursuit of victory. Johnson’s delivery is full of gravitas, suggesting a layered performance that digs much deeper than anything he’s previously taken on.

For Johnson, this role is not just a creative departure but a personal challenge. In an interview with GQ last year, he shared that the opportunity to portray Kerr felt like a chance to break new ground in his career. “It was also an opportunity for me, I realized, to stretch myself in ways that I hadn’t been stretched yet,” he explained. “And also challenge myself in ways that I hadn’t been challenged.” That drive to evolve, both as an actor and a storyteller, is evident in every frame of the trailer.

While Johnson has been busy in other areas—voicing Maui once again in “Moana 2,” returning to the WWE ring, and joining the board of TKO Group Holdings following the WWE-UFC merger—“The Smashing Machine” stands apart as a pivotal moment in his career. It’s not about larger-than-life action heroes or comedic charm. It’s about stepping into someone else’s pain and perseverance, and doing so with authenticity.

Director Benny Safdie, making his solo debut after co-directing acclaimed films like “Uncut Gems” with his brother Josh, brings a raw, almost documentary-style realism to the project. His past work has been praised for its tense, emotionally charged storytelling, and “The Smashing Machine” appears to follow in that tradition. The film is likely to appeal not only to fans of MMA and biopics but also to those interested in the psychological complexities that come with public glory and private battles.

As anticipation builds for the release, “The Smashing Machine” seems poised to redefine what audiences expect from Dwayne Johnson. Known affectionately as “The Rock” by his wrestling fans, Johnson is now forging a new path—one that embraces nuance, hardship, and a kind of storytelling that doesn’t rely on spectacle alone. If the trailer is any indication, his turn as Mark Kerr could be one of the most powerful performances of the year.

With a compelling cast, a gripping true story, and a fearless lead performance, “The Smashing Machine” might not just be a film about fighting—it could be a knockout moment in Johnson’s cinematic journey.
