If you missed the critically acclaimed 2025 biographical film "The Smashing Machine," which stars Dwayne Johnson as former amateur wrestler and MMA fighter Mark Kerr, it is now available to stream on HBO Max. The film, praised by critics as Johnson's best performance to date, premiered on the streamer on Friday, January 23.

The film is written, directed, and produced by Benny Safdie, and premiered at the 82nd Venice International Film Festival on September 1, 2025, before its theatrical release, receiving rave reviews. Johnson completely transformed for the role, shedding 60 lbs to bring authenticity to the character who struggled with addiction and relationship challenges with his girlfriend Dawn Staples, played by Emily Blunt, through the highs and lows of his career. The film also features Ryan Bader, Bas Rutten, and Oleksandr Usyk in supporting roles.

Set in the chaotic early days of MMA, the film follows Kerr at the height of his dominance. In the ring, he's nearly unstoppable—an engineered force of violence. Outside of it, he's falling apart. Safdie refuses to glamorize the sport or Kerr's success, instead focusing on the psychological damage caused by fame, physical punishment, and a growing dependence on drugs. The fights are brutal and unpolished, filmed in a way that makes you feel every slam and strike rather than cheer for them.

Johnson, known for his charismatic, box office persona, has traded it for a deeply internal and often frightening performance. Blunt, who is magnetic, portrays someone caught between love, fear, and exhaustion as Kerr spirals.

"The Smashing Machine" is an intense film that marks a significant turning point for Johnson as a serious dramatic actor. This is not a typical sports movie about winning. It has a darker tone, is more character-driven, and is definitely worth your time.

The film does not seek redemption or inspiration. Instead, it presents a focused, unsettling character study that lingers in the viewer's mind long after the credits roll. "The Smashing Machine" may not attract those looking for a typical sports movie, but for viewers open to something more serious and introspective, it's a rewarding and impressive film and a significant highlight in Dwayne Johnson's career.
