I've always found it intereting that among movies that are successful overseas, comedies are much less represented. (Except for Hollywood films, as an American living in Korea, I find it absolutely embarrasing that there isn't a week that goes by where some Leslie Neilson movie doesn't play on cable.)
Of course, light-hearted (ie, Miramaxed) movies are a dime-a-dozen, but actually comedies are much rare compared to other genres.
That said, however, check out "Barking Dogs Never Bite" from Korea. It's somewhat of a black comedy, although it isn't all that dark.
