District 13: Ultimatum is at its best and silliest in the opening reels, which place French supercop Damien Tomaso (the lanky, bald Cyril Raffaelli, who’s also the film’s stunt coordinator) in a chaotic undercover assignment — he’s in the back room of a nightclub, decked out in a dress with a peekaboo ass and masquerading as a kind of courtesan to a Chinese drug kingpin. When his backup arrives, all hell breaks loose. The sequence is staged with tongue tucked firmly in cheek — the contrast between Raffaelli’s muscular, manly frame and that of his obvious female body-double is faintly hilarious — but it more or less brings the goods, staging an extended martial-arts fight that plays as an affectionate tribute to Jackie Chan in his prime. In other words, props matter, from the stepladder that brings the pain when villains are slammed into it to the priceless Van Gogh painting that Tomaso employs as a delicate weapon at his disposal. You’ll laugh, you’ll wince. It’s a good time.
