Henry Cavill and Tom Cruise in Mission: Impossible—Fallout.

Tom Cruise is his maniac self in Mission: Impossible—Fallout, the sixth installment in the steady franchise—and proof that Cruise is certifiably insane. The movie is one “Wow!” moment after another, and the guy shows no signs of slowing down, even though he’s now 56 years old.

The movie stacks stunt after stunt, featuring Cruise doing everything from jumping out of airplanes, to scaling cliffs, to piloting his own helicopter. It also shows Cruise leaping from one rooftop to another and breaking his ankle against a building—a stunt that shut down production for weeks, but remains in the film, in all its bone-breaking glory.

Do we really care about the plot when some of the best stunts and action scenes ever are here? Thankfully, the plot is a fun, twisted story, so you’ll be interested even when Cruise isn’t risking his life. Yes, there are a lot of, “Hey, haven’t I seen that before?” moments—lots of masks get ripped off, for starters—but the labyrinthine hijinks still feel fresh overall.

No, I’m not going to do much to explain the plot. It wouldn’t really do you any good.

OK, I’ll tell you a little.

Ethan Hunt (Cruise) finds himself on yet another mission to save the world, this time from nuclear terrorists headed by Solomon Lane (Sean Harris), the baddie from the franchise’s prior installment, making a welcome return. This time, Hunt is saddled with an “observer” in August Walker (Henry Cavill), tasked by CIA director Erica Sloan (a so-so Angela Bassett) with making sure Ethan and the IMF complete their mission with minimal funny stuff.

Cruise is sick in the head. Thankfully, one part of his sickness makes him willing to pull off movie stunts like the ones mentioned above. Cruise, while reteaming yet again with director Christopher McQuarrie (now the only director to have helmed two M:I films), manages to pull off his most spectacular cinematic feats yet. The skydive sequence, in which Hunt must work to save an unconscious co-jumper before they go splat, is simply unbelievable (in a good way). There’s a motorcycle chase through Paris streets that demands you see this thing on an IMAX screen.

Cavill, whose facial hair in this film has gotten a lot of attention over the last year, gets a chance to stretch out and play someone far more interesting than his Kryptonian dud. Here, he’s a multi-dimensional badass, especially in a bathroom brawl during which Walker and Hunt try to take out a worthy opponent. Cavill shares in the glory of some of the film’s craziest stunts. That’s not him skydiving, though: Cruise, also a producer on the film, forced Cavill to watch that sequence from the ground in favor of a stunt double.

Alec Baldwin, the original Jack Ryan, takes a break from hosting Match Game to show that he can still throw some big-screen punches as Hunt’s new IMF commander. Vanessa Kirby is sinisterly terrific as White Widow, a sly arms dealer Hunt whom must confront. In her second go-round, Rebecca Fergusson’s Ilsa Faust adds many elements of surprise. Simon Pegg and Ving Rhames deliver their usual, competent support. Lorne Balfe’s score deserves a big round of applause for its adrenaline-inducing contributions.

No matter how much money this movie makes, Cruise needs to slow down at some point. In some ways, Mission: Impossible—Fallout feels like it could be the franchise capper. It’s hard to think of any way Cruise could top what he puts onscreen, action-wise.

Then again, I probably started saying stuff like that when the original Mission: Impossible came out.

Mission: Impossible—Fallout is playing at theaters across the valley, in a variety of formats.
