According to The National Enquirer, Murray, who has script approval, sent Dan Aykroyd and Harold Ramis a box with the newest script shredded into confetti. He added the note “No one wants to pay money to see fat, old men chasing ghosts.”
While Aykroyd, Ramis, and Sigourney Weaver have all agreed and said they want to make a third Ghostbusters movie, Murray has constantly blocked the script development and made complaints about the scripts.
Eventually this prompted Aykroyd to call Murray and say “stop acting like a jerk.” Murray continued to refuse to answer producers’ calls after each rewrite.
His most recent action has only served to anger Aykroyd and Ramis further and the two have now said that they will make the movie without him.
