Tip for U.S. film producer: pick up the rights to Sleepless Night

The 2011 French-Belgian film "Sleepless Night" (Nuit Blanche, actually) is just about a perfect genre film that completely satisfies on its own terms - it will never be mistaken for The Seventh Seal or The Godfather - it's just a great cops-drugs-gangsters action drama, with a super-tight plot, lots of twists and turns, enough but not too much ambiguity (slight spoiler here, but I could never be sure, even after the film, whether the main cop was truly working undercover or if he was a crook - I think the latter). Simply put, story about two cops who rob a drug runner, shooting him to death in the process, leading to an investigation. When a Sicilian mobster nightclub owner - a truly ugly an sinister guy - learns that the cop has the Rx headed for him hie grabs the cop's preteen son and holds him in the huge nightclub he runs until the cop returns the Rx. So this becomes a story about a bad guy trying to do whatever it takes to rescue his son - and the father-son relationship adds a human dimension to the story and draws us in emotionally. The whole story takes place within 24 hours, and most of it during the nighttime hours in the club, so there's a great sense of unity of time and place, very unusual in contemporary movies. The pace is lightning fast, some terrific fight and flight scenes, tension throughout every moment - and also lots of incidental humor, especially the scenes in the night club's restaurant kitchen (the staff reactions as they watch two thugs grapple in the kitchen is hilarious). Main cop - christlike? - has a scary knifewound in his side through the whole ordeal - he can't go to a hospital for fear of being linked to the killing. The only reason this film has flown below the radar is that it's in French with no familiar actors and with rather drab settings; I would guess some smart producer will buy the rights and make an American version, set in Las Vegas or LA - and they'll probably ruin it. Or maybe not.
