Leave it to Beat Takeshi to ridicule the cinematic elephantiasis that has even the Great Scorsese pushing the limits of how long a night out at the movies should last. And that Brady Corbet “Brutalist” guy? Three and a half hours? Who is he kidding?

And trust the often goofy Takeshi Kitano (his real name) to take down a whole genre of Japanese cinema that made him rich and famous — yakuza hitman stories — and do it in 67 minutes, including credits.

With “Broken Rage,” even the title’s a joke, as the director of “Outrage,” and “Outrage Coda” takes a shot at deconstructing the yakuza killer narrative in a self-aware, fourth-wall-breaking farce. He tells us a tidy, dumb geezer-gun-for-hire story, and then spends the second half of the movie lampooning the conventions, set-pieces, character “types” and ways the time-tested-plans of an elderly trigger man can and should go wrong.

The guy “they call Mouse” (Kitano) is a pot-bellied, bowlegged 70something lump who dresses all in black, picks up his assignments in an envelope left by a mysterious “M” at his regular dining spot, the Cafe Lake.

The proprietor (Takashi Nishina) always asks him who “M” is, and the cagey Mouse always answers “I have no idea.”

As you’d expect, thanks to 1467 hitman movies that preceded it, that envelope contains a photo and the routine of the intended mob victim.

So the wily Mouse dons his black jacket, pants and shades and walks right into a club to shoot up a table packed with young punks. He switches coats, adds a cap and pedals off into the night as the oldest delivery boy in Tokyo. Another guy, with bodyguards with him, must be surveiled at the gym and trapped when he strips to just his tattoo’d birthday suit for a dip outside the sauna.

Careful as he might seem, the Mouse is grabbed by the cops, ID’d in a lineup and beaten until he agrees to go undercover to entrap drug smuggling mobsters. How’ll he join the gang?

Simple. The old man will visit a bar a mob leader (Hakuryû) frequents and “handle himself” in a fight an undercover cop picks with him. Just like that, with not so much as a “check him out,” he’s a mob bodyguard, showing off his killer instincts to his new crew while baiting them into a trap.

Kitano skips over a vast collection of conventions and cliches of such movies, skipping past “wiring” Mouse up, etc., to pretty much wrap that tale up in half an hour.

The “joke” to the first half of “Broken Rage” is Beat Takeshi as a past retirement age “hard” man in the Liam, Bruce, Sly, Mel and Denzel mold. Yeah, he’s too old to be that quick, punch that hard and see danger in a dark parking garage at night whilst wearing sunglasses. It’s funny that we let our action heroes “sell” this lie well into their ’70s.

The second half of the film treats us to a counter-narrative where Mouse goes through the same hit-list and same routine, with one disastrous result after another. Even the cafe chairs collapse under him while he’s picking up his envelopes.

The entire deadpan affair is more reasonably amusing than hilarious, but the pauses in the action, with the screen going to black and “users” of this Amazon streaming movie commenting their complants– “That’s it?” “That’s not a movie” and “On this budget, this is what you get” — are laugh out loud funny.

Yes, movies are getting too long as they’re tailored for a home viewing audience used to binge watching streaming series. Yes, every filmmaker is pitching those streamers, or being lured by Amazon, Hulu or Netflix money.

Takeshi gets it. And when he got that Jeff Bezos money to deliver one of his patented serio-comic thrillers, guess who’s actually the butt of his jokes?
