From an interview of Harold Ramis in The Believer:
BLVR: Rumor has it that you turned down the chance to direct Disney’s remake of Guess Who’s Coming to Dinner because you felt they weren’t interested in really exploring racism.
HR: The way they wanted to do it didn’t have a lot to do with the colossal amount of pain and violence that swirls around racial injustice. It would’ve been like an episode of The Jeffersons. What’s the point? But who knows, maybe that’s as much as most people want. I can’t tell you how many people have told me, “When I go to the movies, I don’t want to think.”
BLVR: Does that offend you as a filmmaker?
HR: It offends me as a human being. Why wouldn’t you want to think? What does that mean? Why not just shoot yourself in the fucking head?
