So after Dan Aykroyd came out and said that Ghostbusters 3 was in "suspended animation." The studio, the director Ivan Reitman and producer Harold Ramis feel, "there must be a way to do it, but Bill Murray will not do the movie. He doesn't want to be involved." But now Murray has come out and said that the movie is actually a possibility for him!
He recently participated in an interview with WGNTV, and he was asked about the possibility of participating in the long awaited third Ghostbusters film. He responded with a short and simple answer... "well, it's a possibility."
So it doesn't sound like he's completely counted himself out yet, which is great news! Either Murray is just being polite and doesn't want to get into a discussion about it, or there's actually a chance that the movie could move forward with him attached.
It's crazy seeing how no one seems to be on the same page about Murray's involvement with Ghostbusters 3, even Murray is contradicting himself at times! He's probably doing it on purpose. Fact of the matter is, they can't make the movie without him.
