Ivan Reitman

A good actor is someone who knows how to take the part and make it real and make it honest and be effective in it. If it's in a funny movie and, as long as they are cast in an appropriate way, humor will come from it.

I watched 'Ghostbusters' from the age of four. It's my favorite movie, still. Bill Murray's, like, the weirdest straight man that you've ever seen. He's convinced that he's the normal one, even though he's definitely not.
