The French-language sequel to the 2006 French-language “OSS 177: Cairo, Nest of Spies,” it’s the continuing adventures of French superspy Hubert Bonisseur de la Bath or Agent 117 or, as one person calls him, Double-One Seven.

If you don’t like silly movies, heed this advice: Stay away from “OSS 117: Lost in Rio.” It is seriously silly.


The French-language sequel to the 2006 French-language “OSS 177: Cairo, Nest of Spies,” it’s the continuing adventures of French superspy Hubert Bonisseur de la Bath or Agent 117 or, as one person calls him, Double-One Seven.


Reprised with a completely straight face by Jean Dujardin, 117 is suave, quick on his feet, always ready to mix it up with the ladies and, like a certain character in Warren Zevon’s “Werewolves of London,” his hair is perfect.


Set in 1967 – 12 years after the first film – the action picks up with 117 twisting away to Dean Martin singing “Gentle on My Mind” at a swingin’, otherwise all-girl party in Paris.


All it takes to get him on his next assignment is word that a South American wrestling impresario possesses microfilm with names of WWII Nazi collaborators who are now living in Brazil. And before you can say Moneypenny, he’s off to Rio, where he meets up with an evil cabdriver, some masked wrestler gunmen (all, of course, notoriously bad shots), and a new partner – gorgeous, no-nonsense Israeli Secret Service Col. Dolores Koulechov (Louise Monot).


But the film is all nonsense, and that’s the beauty of it. Our hero is blissfully unaware that he’s racist and sexist (don’t worry, it’s absurdly played for laughs). “Some people have adventures; I am an adventure,” he brags to Dolores, hoping to bed her. A square-jawed CIA pal of 117 shows up – nicely named Bill Trumendous (Ken Samuels) – and speaks French with a bad American accent, now and then tossing in a little English when he wants to insult someone who doesn’t speak English.


There are the biggest and brightest colors onscreen since Austin Powers spoofed the Bond films, along with the splashiest split-screen work since the first “Thomas Crown Affair.” Sure, a lot of the gags fall flat, but most of them work wonderfully, whether they’re about a crocodile-infested river or an acid-fueled love-in on a beach, from which 117 emerges with less-than-perfect hair.


Don’t try to keep track of bad guys with guns or characters’ names. There are just too many of them.


But it might be fun to note how many times 117 flashes a self-assured smirk or a big, egotistical smile at every woman he sees.


This guy may bounce back from injuries like Wile E. Coyote, but film purists might go after everyone involved in the production when they see the rip-offs of – oops, sorry, the appreciative nods – to both “Vertigo” and “North by Northwest” during the big climax.


The fact that Dean Martin’s voice bookends the film with “Everybody Loves Somebody” adds yet another feather to tickle everybody watching.
