"[On Young Frankenstein] I started writing two pages about what I would like to see it become [...] I would like it to be a happy ending. My agent called me…he said, "I wanted to do a film with you and Marty Feldman and Peter Boyle." So I wrote a couple more pages with the Transylvania ending, and she said "This is great, we should get Mel Brooks to direct." And he wouldn't direct something he didn't conceptualize. The phone rings, it was Mel, and he says "what are you getting me into?" I said, nothing that you don’t want to get into."
