The Smashing Machine ★★★
(M) 123 minutes

When you start out as a big guy, turning yourself into an even bigger guy might not seem like the most taxing kind of transformation. But as the real-life mixed martial arts champion Mark Kerr in The Smashing Machine, Dwayne Johnson is close to unrecognisable, and not just because of his dark, tightly curled wig, or the work put in by his makeup team and his personal trainer.

Johnson’s acting talent has always been visible to anyone willing to see it, but he’s spent the majority of his Hollywood career in bantering action-hero mode, outwardly relaxed and above it all.

The Kerr of the film is a smooth talker with a carefully crafted public persona, but never truly relaxed: just as he dominates in the ring, he takes up all the available space in his personal life, and not just physically.

In a word, he’s an obsessive, with precise but constantly shifting ideas about how everything should be done, whether it’s the milkshake his loyal girlfriend Dawn (Emily Blunt) prepares for him each morning, or the cactus growing in their backyard in suburban Arizona, inspired by his love of Road Runner cartoons.

As a fighter, he doesn’t just want to win – he needs to win, to the point where he refuses to contemplate the thought of losing. When he does begin to lose, he falls apart: set over a few years in the late 1990s, The Smashing Machine follows his decline into opioid addiction, the decay of his relationship with Dawn, and his eventual attempt at a comeback.

This is the first movie written and directed solo by Benny Safdie, previously known for his collaborations with his brother Josh, such as Good Time and Uncut Gems – character studies of extreme personalities, done in a quasi-documentary style at once urgent and consciously old-fashioned.

In many ways, The Smashing Machine is in the same vein, recreating an era before mixed martial arts became a multi-million-dollar global industry (the fights we witness are mostly in Japan). Actual fighters make up much of the supporting cast: the onetime heavyweight champion Ryan Bader is straightforwardly effective as Mark Coleman, Kerr’s mentor, best friend and rival.
