I am big on comedies, and the funniest movie of all time (or at least the last ten years) is french: Dîner de cons, the funniest movie I may ever have seen. Some old classics are my wifes favorite movie of all time, Rabbi Jacob, and another really good de Funès movie (he's perhaps the best comic of our time, tied with Coluche) is La Soupe aux choux which my kids like thanks to a few choice scenes. There's also a movie with both Coluche and de Funès, L'aile ou la cuisse. Actually, any movie with either of those two you might find in the US and you'll be ok.

Standard fluff stuff for fun, and this isn't PC because these guys are friends of Sarko the starmanic, but L'Enquête Corse which was on tv last week here was pretty good, though Petillon's bd it was made from was better. Clavier and Reno are a decent team, and also in Les Visiteurs which I'm not sure but also might still be the top grossing film in French history. The movie it beat out, another movie with de Funès and Bourvil (another great comic), La Grande Vadrouille. Actually, any movie made by Gerard Oury and you're pretty good.

The best hockey movie of all time isn't Slap Shot, it's Les Boys. Another good recent Canadian movie is Bon Cop Bad Cop which just came out in video, or also, a couple of years back, La Grande séduction is really good too.

Since you mentioned Goodbye Lenin, which I also liked, and if you did too, there's Tout le monde n'a pas eu la chance d'avoir des parents communistes of Josiane Balasko. It's a cute film, nothing super exceptional but along the same lines. Actually, anything with Josiane Balasko and you're probably going to be ok.
