Not very surprising. I doubt many of if movies were release in the US. He was so beloved here. He was always kinda grumpy and funny and had a very sharp take on society. So sad.
Grand Froid is quite ok in a very dark humour (kinda belgian, may be a belgian movie actually) way. I like Avant l'aube quite a bit (not a comedy at all this one).
His most famous roles as far as (drama-, in some cases) comedies are Cuisine et dépendance, Un air de famille, Didier, Mes meilleurs copains, le gout des autres, On connait la chanson....
