Aaah I was going to post that :D! It stars one of my favorite comedic actors, Benoît Poelvoorde who is belgian. I'd encourage anyone with a taste for foreign films to check out "C'est arrivé près de chez vous" (Man Bites Dog in english) another great movie of his (features lots of violence and serious themes, not a family movie).
> Benoît Poelvoorde It looks like a very French first name and a very Dutch last name. Is that common in Belgium? Is there a significant overlap between the linguistic communities of Belgium?
Some old people in french speaking still speak dialect dutch. Not the "new" generation.

Additionally, Wallonië is also french speaking and not dutch.
So my guess is that it's pretty common ;)
