Nah, that was an American film and from the early 80s, the film i'm talking about is a French film, and it was made in the late 90s, most likely early 2000s. Theres like a scene where this person dies and another person comes over to her apartment and she tries to hide the body in a strange place and its so funny as she tries to carry on as if everything is ok but its not.
Curses, I'd hope that it might be your film. Perhaps someone else will chime in who has seen your mystery movie. Good luck!
