Now director Ivan Reitman has decided to chime in about a possible Ghostbusters 3 movie. His response to another film in the franchise actually sounds like the most definitive answer fans of the franchise will hear... as of right now (via Slash Film).
"Bill Murray has never actually read anything. He may have read ten pages at some point, but he’s never read a script. But he’s never been interested, either. That part is true. It wasn’t Ghostbusters in particular, it’s just, he’s been carrying on his life in a different way, in terms of the kind of parts that he’s wanted to pursue. I mean, he’s a really brilliant actor, comedian, personality. I’ve worked with him now five times, and I would love to work with him again. I’d hope that he could be in this film. He could be, he might not be, I really don’t know."
It was also reported that Reitman did sound optimistic about a third movie but he also said it is still a ways away from production (and a green light).
"[I]f we can find a way to make a film that’s somewhat as magical as [Ghostbusters] finally turned out to be, then it’s worth making. If we can’t, then we probably won’t do it. And I think that’s really what’s been taking so damn long. We had a couple of scripts that were quite good, that we just didn’t think quite had it. And one of them was particularly centric to Bill, and we just couldn’t get him to read it. And so that one didn’t get made, even though it was pretty damn good. So we’ve been thinking of alternatives, and we’re actually making some real progress, and we’ll see what happens. That’s the most honest answer I can think of."
Development limbo continues for Ghostbusters 3.
