Initial Thoughts

Not nearly as pleasurably anxiety-inducing as his previous films with brother Josh, Benny Safdie’s solo directing debut finds the filmmaker enabling star Dwayne Johnson’s push into the realm of ‘serious actor’ – and on that level, ‘The Smashing Machine’ is a success. The Rock rises to the occasion here with his measured, compelling, and complex portrayal of real-life UFC fighter Mark Kerr, showing vulnerability and humanity that he has largely not explored in his action-heavy resume to date.

As a film overall, ‘The Smashing Machine’ – based extensively on the 2002 HBO documentary of the same name – is less effective. It lacks context for Kerr’s story, which may leave viewers not familiar with the UFC or MMA bewildered, and it’s episodic in nature, weaving the highs and lows of Kerr’s career from 1997 to 2000 around his fraught, co-dependent relationship with girlfriend (and eventual wife, then ex-wife) Dawn Staples (Emily Blunt). Take away Johnson’s absorbing performance, and it’s a standard sports biopic with a weirdly muted energy.

Story and Direction

Safdie seems to take a lot of incidents and even lines of dialogue from ‘The Smashing Machine: The Life and Times of Extreme Fighter Mark Kerr,’ the HBO documentary, and his tendency to film in a cinema-verité style brings this film even closer aesthetically to the 2002 doc. The main difference, of course, is that this version features Dwayne Johnson as Kerr, and while we don’t get a lot of backstory on either him or his chosen field, we are nevertheless drawn into his struggle.

Kerr fights on several fronts even when he’s not in the ring. He’s a soft-spoken, gentle, kind man with a vulnerable center – he won’t even go on certain amusement park rides because they’ll hurt his ‘tummy’ – yet he’s also possessed of a deep inner rage that will explode out of nowhere and result in a bedroom door smashed to splinters on the floor. He doesn’t know how to handle defeat because he’s ‘never lost,’ even saying so in an interview before a match in Japan (where he frequently fought). Yet this is also a man who grudgingly realizes that he can’t win all the time, a realization borne out in the film’s final scenes.

Opioids and Dawn are what Kerr battles the most, the former for the pain and wear of his profession and the latter for the pain and wear of co-dependency. In several instances, Dawn comes out into their living room to find him sitting in a stupor, staring at the TV. She’s no angel herself when it comes to substances, with Kerr stunned late in the film when she refuses to stay away from the goodies herself in support of his emergence from rehab. ‘You’re no fun anymore!’ she shrieks at him with almost deliberate cruelty, despite Kerr's earlier descent into addiction being nothing less than harrowing.

The brawls inside the ring are less emotionally fraught but more physically brutal. Boxing may be the ‘sweet science,’ but UFC fighting is frankly nothing less than barbaric. Yet the fighters themselves are respectful to each other outside the ring, even friends, which provides its own touching moments.

Safdie shoots all this, as mentioned earlier, in a somewhat detached documentary style, but the compilation of incidents from Kerr’s life and career never take on an organic momentum of their own. That may be Safdie in part trying to avoid the usual rise-fall-return of most sports biopics (and biopics in general), which is commendable. But he still can’t avoid a number of the tropes and the film almost fights itself, trying to show a documentary restraint yet not quite reaching any real emotional heights – except in Johnson’s raw performance.

Cast and Performances

‘Raw’ is really the right word for Dwayne Johnson’s performance (which does bring to mind the Safdies’ reinvention of Adam Sandler in ‘Uncut Gems’), and fans may be unnerved to see him sobbing at several points in the film. Wearing prosthetics to bury himself more in the role, Johnson visibly digs deep and delivers, even if the viewer is aware that he’s also thinking about his award-season run.

Emily Blunt’s Dawn Staples is a problematic and not especially sympathetic character; while Blunt throws herself into the part (their biggest fight, climaxing in a bathroom, is intense and even frightening), the character is difficult because she’s either subservient to Kerr or selfishly manipulative toward him. Dawn is both exasperating and the typical ‘girlfriend/wife’ we see in sports biopics, but the movie never quite burrows under her skin.

Much of the rest of the film – in keeping with Safdie’s seeming desire to replicate as much of the documentary as possible – is cast with real people from the world of MMA and UFC playing either themselves or fictionalized versions of other real people. Ryan Bader in particular is quite good as Kerr’s former friend Mark Coleman, bringing sensitivity, decency, and honesty to a character whose loyalty Kerr constantly tests.

Final Thoughts

As we said at the top of this review, the main focus of ‘The Smashing Machine’ – Dwayne Johnson’s transformative performance – is what works best. Which is a good thing, both for him and the movie, although no doubt debates will rage over whether this is a shameless bid for awards recognition from an actor whose chops – like those of fellow wrestlers-turned-actors John Cena and Dave Bautista – have not always been taken seriously.

Still, Johnson does step up, although in the end ‘The Smashing Machine’ itself is serviceable, occasionally fascinating, and intermittently moving. We’re not sure what the film says in the end: Mark Kerr was a UFC and MMA pioneer before they became cultural behemoths, and in a sense he was passed by as a result. But since that has been chronicled already in a documentary, does a narrative version have a point? That’s the barrier ‘The Smashing Machine’ struggles to break through.

‘The Smashing Machine’ receives a score of 75 out of 100.
