The actor charms as a swaggering stunt man, alongside an underused Emily Blunt, in the latest skull-rattling action movie from David Leitch.Like a certain energized bunny, Ryan Gosling’s charmer in “The Fall Guy” takes a licking and keeps jauntily ticking as he runs and leaps, tumbles and punches and vaults through the air like a rocket. The actor has shed his “Barbie” pretty-in-pink look, if not his signature heat-seeking moves to play Colt Seavers, a stuntman with a long résumé, six-packs on his six-packs and a disregard for personal safety. Plunging 12 stories in a building atrium, though, is just another bruising day on the job for Colt until, oops, he nearly goes splat.Directed by David Leitch, “The Fall Guy” is divertingly slick, playful nonsense about a guy who lives to get brutalized again and again — soon after it starts, Colt suffers a catastrophic accident — which may be a metaphor for contemporary masculinity and its discontents, though perhaps not. More unambiguously, the movie is a feature-length stunt-highlight reel that’s been padded with romance, a minor mystery, winking jokes and the kind of unembarrassed self-regard for moviemaking that film people have indulged in for nearly as long as cinema has been in existence. For once, this swaggering pretense is largely justified.There’s a story, though it’s largely irrelevant given that the movie is essentially a vehicle for Gosling and a lot of stunt performers to strut their cool stuff. Written by Drew Pearce and based (marginally) on the 1980s TV series of the same title starring Lee Majors, it opens shortly before Colt’s 12-story plunge goes wrong. After some restorative time alone baring his torso, he resumes stunt work, drawn by the promise of a reunion with his ex, Jody (a welcome if underused Emily Blunt). She’s directing a science-fiction blowout that looks like the typical big-screen recycling bin, with bits from generic video games, the 2011 fantasy “Cowboys & Aliens,” and both the “Alien” and “Mad Max” franchises. Cue the flirting and the fighting.Leitch is a former stunt performer who has his own estimable résumé, which includes doubling for Brad Pitt, whom he later directed in “Bullet Train.” Leitch has a company with Chad Stahelski, yet another former stunt performer turned movie director who’s is best known for the “John Wick” series with Keanu Reeves. Working in tandem with physically expressive performers like Pitt, Reeves and Charlize Theron (Leitch directed “Atomic Blonde”), the two filmmakers have, in the post-John Woo era, put a distinctive stamp on American action cinema with a mix of martial-arts styles, witty fight choreography and, especially, a focus on the many ways a human body can move (or hurtle) through space.There are arsenals of guns and all manner of sharp objects that do gruesome damage in Leitch’s movies, “The Fall Guy” included. Yet what seizes your attention here, and in other Leitch and Stahelski productions, is the intense physicality of the action sequences, with their coordinated twisting, wrenching and straining bodies. A signature of both directors is that they emphasize the intense effort that goes into these physical acts, which is understandable given their backgrounds. (Like Fred Astaire, they show off the body, head to toe.) In their movies, you hear the panting and see the grimacing as fists and feet and whatever else happens to be around (a fridge door, a briefcase, a bottle) connect with soft tissue and hard heads.Like the impressively flamboyant practical effects in “The Fall Guy,” this focus on the body reads like a rebuke to the digital wizardry that now characterizes action movies. Each time Colt crashes to the ground in “The Fall Guy,” the moment announces his and the movie’s authenticity (however you want to define that). There’s a macho undertow to this — real men, real stunts — which dovetails with how his romance with Jody is, by turns, comically, sentimentally and, at times, irritatingly framed, including via split-screen mirroring à la “Pillow Talk.” Jody may be Colt’s boss, but he’s the one who has to save the day after some gnarly business with a star and producer (Aaron Taylor-Johnson and Hannah Waddingham).The issue of authenticity is a thread that the story jokingly pulls with a scene in which Colt’s face is digitally scanned and in a subplot involving a deep fake. (It’s funnier if you don’t think too hard about the fact that A.I. was an existentially fraught issue in the 2023 actors’ strike.) Tapping into his inner Tom Cruise, Gosling makes love to the camera and performs some of his own showstopping moves, at one point while atop and almost under a speeding garbage truck. Given that “The Fall Guy” is an ode to stunt work, it’s only right to note that the actor’s stunt doubles were Ben Jenkin and Justin Eaton, his driving double was Logan Holladay while his double on that nosebleed of a plummet was Troy Brown. Kudos, gentlemen.The Fall GuyRated PG-13 for falls, fights, crashes and explosions. Running time: 2 hours 6 minutes. In theaters. More
