What the Hell was that? DAVE COULIER? Are you serious. Bill Murray IS Peter Venkman. Yes I loved the animated series, but they were just actors there to here extend the franchise. In the live movies, Bill Murray is Peter Venkman.Yes I know I said in the live movies and Ghostbusters 3 is going to be animated, but that's secondary to the live movie. Bill Murray IS Peter Venkman, no one else.
