What’s It About?: What we’ve got here is a biopic about retired mixed martial artist Mark Kerr, played by Dwayne Johnson, a veteran of athletic combat himself. Kerr was active in the ring before MMA became one of the most popular sports in the world, so if you’re an obsessive UFC historian, perhaps you’re already familiar with his story. But on the other hand, if you’ve only become a fan within the past ten years or so, I wouldn’t be surprised if you’ve never heard of him before. The Smashing Machine focuses on a few of Kerr’s fights in Japan during the end of the last century, and otherwise we get a close view at Mark’s chaotic home life in Arizona with his girlfriend Dawn (Emily Blunt). And it must be mentioned that we also get to spend plenty of time with Mark Coleman (Ryan Bader), Mark’s fellow grappler and close confidant.

What Made an Impression?: What’s It All About, Smashy?: The Smashing Machine is not exactly your typical sports biopic. I don’t say that as praise, nor criticism, but merely observation. Oh sure, it’s got training sequences and behind-the-scenes struggles, but it doesn’t exactly build to the sort of climax you’re probably expecting. Occasionally, it feels like its reason for existing is to unveil the untold truth of MMA. Elsewhere, it’s something else entirely: a stark portrait of addiction, as Mark becomes dangerously hooked on painkillers and Dawn’s alcoholism brings her to the edge of utter destruction. Of course, there’s no reason it can’t be both of those things, but this particular case is an oddly shaped assemblage that I’ve never quite encountered before.
Letting Us In: This movie raises the question: why Mark Kerr in particular? He doesn’t seem like the most influential or most successful figure in his sport’s history, though he certainly made a noticeable impact. As far as I can tell, The Smashing Machine happened because Johnson and writer/director Benny Safdie were fans, and they had the pull to make it happen. And on top of that, the real Kerr was remarkably willing to let his unvarnished story go on the screen. That vulnerability certainly comes through via the unflinching portrayal of Mark and Dawn’s chaotic relationship, as well as the remarkably supportive friendship between the two Marks.
This Would Have Played Out Very Differently with Instant Replay: One more observation before I wrap things up: this movie contains a lot of nitpicking, mostly in terms of Mark and Dawn getting on each other’s nerves. But a very different type of pedantry really stood out as something unusual. Early on, Mark loses a fight, but he’s convinced that his opponent has used an illegal move on him. So he marches right out of the stadium to immediately plead his case to the guy in charge of everything while he’s still a sweaty mess in his grappling skivvies. What struck me most about this scene was how much it was devoted to a procedural matter. It also serves a thematic purpose regarding Mark’s journey, but from my vantage point, it mainly underscored how much rules and their interpretation matter in sports, which can be both kind of fun and also kind of infuriating.
