Genre?

A correct translation will be "immoral tale", but in french morale also means the lesson you take out of a story. Maybe Gavras meant that you can't figure how you will act if you were José Garcia's character.

It is a black comedy. Maybe it's a french movie directed by a greek, but the Westlake spirit is what carries all the movie. A noir comedy with black humor, if you want, but the humor ends up being much lighter than it looks.

"He said, among other things, that this film is not a black comedie, in fact, he said that it was't a comedie at all."

I watched it on television where it was described as a "comedy". I'd agree with the director that it wasn't even a black comedy. Yes, there were some humourous moments; but as Gavras arguably implies, watching the mental disintegration of a human being into some sort of socio - pathic murderer (and yes later, some sort of redemption/resurrection)isn't necessarily all that funny. What I will say is that the acting, particularly from the leads was first class and there some really well placed twists and turns in the narrative. The ending was delicious.
