I'll Do Anything (1994)
The best part of this movie is when Nick Nolte's character is ranting at some movie executives and he accuses them of "posing for pictures nobody is snapping." That's a great line.
But there was also a hilariously honest secondary character named Nan, who says things like, "I couldn't help overhearing you because I was intentionally eavesdropping."
Oh, and the ex-wife, who only appears briefly, is also hilarious, though perhaps more subtly so.
I guess it was a pretty good movie.
