Speaking to the Daily Mail, the comic actor revealed that killing off his character Peter Venkman was his own suggestion.
"I'll come back in Ghostbusters 3 only if I get to be a ghost," Murray commented. "I said to them, 'I'll do it if you kill me off in the first reel'. So now they are going to have me as a ghost in the film."
Discussing his thoughts on the big budget comedy franchise, Murray said that he disliked the second Ghostbusters because it was too driven by spectacle.
"The first 45 minutes of the original Ghostbusters is some of the funniest stuff ever made," he remarked. "The second one was disappointing, because the special effects guys took over. I had something like two scenes - and they're the only funny ones in the movie."
