Seemingly the only acting award that Jean Dujardin didn't win for The Artist was the César, France's Oscar equivalent, which went to Omar Sy of The Intouchables. Sy's breakout performance proved better than that unexpected box-office juggernaut, and so it is in On the Other Side of the Tracks.
David Charhon's buddy-cop comedy finds him playing Ousmane, a vigilant detective in a department that just wants its officers to keep their heads down and not rock the boat; since Sy is black, ancient rules of cinema dictate that his reluctant partner be a straight-laced white dude from a nicer part of town. "You're good in your neighborhood," by-the-books Franois (Laurent Lafitte) tells the spirited Ousmane shortly after they're paired together to solve a murder, "but this is Paris."
The two go on to argue about the plight of their respective neighborhoods, butt heads over their contrasting styles, and begrudgingly build respect for one another. All of which is a long way of saying that there are few clichés of the genre that Charhon doesn't indulge in, but he does a few of them well enough for the film to occasionally be funny, even if it's never close to inspired. At least the partners never argue over which radio station to listen to.
