The Smashing Machine is a 2025 biographical sports drama that chronicles the tumultuous life and career of Mark Kerr, a legendary figure in the early days of Mixed Martial Arts (MMA) and the Ultimate Fighting Championship (UFC). Directed by Benny Safdie and starring Dwayne Johnson in what critics are calling a career-defining performance, the film provides a gritty, unvarnished look at the physical and psychological toll of professional fighting during the late 1990s and early 2000s.

Released theatrically in the United States on October 3, 2025, by A24, the film focuses on a specific three-year window (1997–2000) rather than following a traditional birth-to-retirement narrative. It explores Kerr’s rise to dominance in the Pride Fighting Championships in Japan, his struggles with narcotic painkiller addiction, and his volatile relationship with his girlfriend, Dawn Staples, played by Emily Blunt.

When was The Smashing Machine released?

The Smashing Machine had its high-profile world premiere at the 82nd Venice International Film Festival on September 1, 2025. Following its critical success in Venice, where director Benny Safdie was awarded the Silver Lion, the film was screened at the Toronto International Film Festival (TIFF) on September 8, 2025. It eventually saw a wide theatrical release in the United States and Canada on October 3, 2025. For viewers who missed the theatrical run, the film transitioned to digital streaming platforms on November 4, 2025.

Why Dwayne Johnson underwent a physical transformation for the role

Dwayne "The Rock" Johnson has spent decades as a global action icon, often playing invincible heroes with a signature charismatic smile. In The Smashing Machine, Johnson undergoes a radical departure from his established persona. To portray Mark Kerr, Johnson utilized prosthetic makeup to alter his facial structure—specifically his brow and nose—to more closely resemble the real fighter. Beyond the makeup, Johnson’s performance is defined by a physical vulnerability rarely seen in his blockbuster work.

The film demands a depiction of a man whose body is simultaneously his greatest weapon and his greatest liability. Johnson’s portrayal captures the sluggishness of a man under the influence of painkillers and the explosive, raw power of a collegiate wrestler turned heavyweight champion. This is not the clean-cut action of a superhero movie; the fight scenes are choreographed to look desperate, exhausting, and excruciatingly painful. Johnson reportedly earned a $4 million salary for the role, a significantly lower figure than his usual blockbuster fees, signaling his commitment to the artistic integrity of this A24 project.

The directorial vision of Benny Safdie and the use of 16mm film

Benny Safdie, known for co-directing high-tension films like Uncut Gems and Good Time, makes his solo directorial debut with The Smashing Machine. Safdie also served as the film's writer and editor, bringing a singular, hyper-realistic vision to the project. One of the most striking technical choices in the film is the decision to shoot predominantly on 16mm film, with select sequences captured on 70mm and even vintage VHS cameras.

This aesthetic choice serves a dual purpose. First, it mimics the visual texture of the late 90s, the era in which the story takes place. Second, it creates a "quasi-documentary" feel that grounds the film in reality. The graininess of the 16mm footage enhances the grittiness of the locker rooms, the dimly lit hotel rooms in Tokyo, and the chaotic intensity of the Pride FC ring. The cinematography by Maceo Bishop eschews the polished, high-definition look of modern sports broadcasts in favor of something that feels lived-in and visceral.

Who are the key cast members in The Smashing Machine?

The film features a blend of Hollywood A-listers and authentic figures from the world of combat sports, contributing to its sense of realism.

  • Dwayne Johnson as Mark Kerr: The protagonist, a powerhouse wrestler struggling with the demons of fame and addiction.
  • Emily Blunt as Dawn Staples: Kerr’s girlfriend and eventual wife. Blunt’s performance is pivotal, portraying a woman caught in the middle of Kerr’s addiction and the violent world he inhabits. Her chemistry with Johnson, previously seen in Jungle Cruise, is utilized here for much darker, more dramatic stakes.
  • Ryan Bader as Mark Coleman: The real-life MMA champion Ryan Bader portrays Mark Coleman, Kerr’s close friend and mentor. The relationship between Kerr and Coleman is a central emotional pillar of the film, showcasing the brotherhood that exists between fighters.
  • Bas Rutten as Himself: In a move that delighted MMA historians, legendary fighter Bas Rutten plays himself. Rutten’s presence provides an authentic bridge to the era the film depicts.
  • Oleksandr Usyk as Igor Vovchanchyn: Professional boxing champion Oleksandr Usyk takes on the role of Vovchanchyn, Kerr’s formidable rival in Japan. Usyk’s participation adds a layer of genuine combat expertise to the fight choreography.

How the movie compares to the 2002 documentary

The Smashing Machine is inspired by the acclaimed 2002 HBO documentary of the same name, directed by John Hyams. While the documentary provides a firsthand look at Kerr’s life through archival footage and interviews, Safdie’s film is a dramatized exploration of the same themes.

The 2025 film focuses heavily on the psychological "internal" fight. While the 2002 documentary was groundbreaking for showing the dark side of the sport during its "No Holds Barred" infancy, the Safdie film uses the narrative structure of a drama to delve deeper into the domestic life of Kerr and Dawn Staples. Some critics noted that while the original documentary is the definitive historical record, the 2025 movie is a "character study" that uses Kerr’s life to explore broader themes of masculinity, pain, and the pursuit of greatness.

What is the plot of The Smashing Machine?

The narrative arc of the film is intentionally narrow, focusing on the years 1997 through 2000. It begins with Kerr at the height of his powers, transitioning from a successful collegiate wrestling career into the burgeoning world of the UFC. However, the heart of the story lies in Japan, where Kerr participates in the Pride Fighting Championships.

The film depicts the brutal reality of the "Vale Tudo" style of fighting permitted at the time, where rules were minimal and the physical damage was maximal. To cope with the injuries sustained in the ring, Kerr begins a downward spiral into addiction to narcotic painkillers. The plot follows the tension between his professional success and his deteriorating personal life.

One of the film's most harrowing sequences involves Kerr’s overdose and his subsequent attempt at rehabilitation. The strain on his relationship with Dawn Staples is portrayed with raw honesty, avoiding the sentimental clichés often found in sports biopics. The film culminates in the year 2000, around the time of the Pride Grand Prix, where Kerr’s physical and mental state reach a breaking point.

Why is the soundtrack by Nala Sinephro significant?

The musical score for The Smashing Machine was composed by Belgian musician Nala Sinephro. Known for her ambient and jazz-influenced work, Sinephro provides a soundscape that is atmospheric and haunting rather than traditionally "epic" or triumphant.

The score emphasizes the isolation felt by Kerr, even when surrounded by thousands of cheering fans in a Japanese arena. One notable musical moment includes the use of the track "Corridor of Dreams" by The Cleaners from Venus, which plays in its entirety during a pivotal scene where Kerr suffers a devastating and humbling loss. This choice of music highlights the film's indie sensibility and its focus on emotional resonance over conventional sports tropes.

Where was The Smashing Machine filmed?

Principal photography for the film took place between May and August 2024. The production traveled to various locations to capture the global nature of Kerr’s career:

  • New Mexico, USA: Used to film the domestic scenes and early wrestling sequences.
  • Vancouver, Canada: Served as a production hub for various interior shots and training sequences.
  • Tokyo, Japan: Crucial for recreating the atmosphere of the Pride Fighting Championships. The neon-lit streets and the specific aesthetic of the Japanese arenas are central to the film's middle act.

Analysis of the critical reception and box office performance

The Smashing Machine received generally favorable reviews from critics, maintaining a 70-73% approval rating on platforms like Rotten Tomatoes. Critics praised the "transformative" nature of Johnson's performance and Safdie's "gritty, unadorned" direction. The film was lauded for its refusal to provide a simple "underdog makes good" ending, instead opting for a more complex look at the aftermath of a combat career.

However, the film’s box office performance was more modest. In its opening weekend, it grossed approximately $5.8 million, finishing third at the box office. Some industry analysts attributed this to the film's "R" rating and its niche subject matter, which appealed more to MMA fans and cinephiles than to the general audience that typically flocks to Dwayne Johnson’s family-friendly action films. A24’s digital-centric marketing campaign was also noted for perhaps failing to reach older adult audiences who might have been interested in a serious drama.

Dwayne Johnson responded to the box office numbers by emphasizing that the project was a personal mission rather than a commercial one. He stated that the film "changed his life" and allowed him to disappear into a role in a way he never had before.

What are the main themes of The Smashing Machine?

The film explores several profound themes that transcend the world of MMA:

The Price of Greatness

Mark Kerr was driven by an obsession to be the best in a sport that, at the time, had very little mainstream acceptance. The film asks what a person is willing to sacrifice—their health, their relationships, their sanity—to reach the pinnacle of a violent profession.

Masculinity and Vulnerability

Despite his massive physical stature, the Mark Kerr of the film is a deeply fragile individual. The movie deconstructs the image of the "invincible" warrior, showing the quiet moments of sobbing in locker rooms and the desperate need for emotional support.

The Cycle of Addiction

The film provides a stark look at the opioid crisis within professional sports. Kerr’s addiction is not portrayed as a moral failing but as a tragic consequence of the physical demands placed upon his body.
