Bill Murray called in to the Howard Stern show this week and talked a little Ghostbusters III with the host, saying, "There's a script somewhere [on my desk], but I haven't read it yet. I feel bad." We'd feel like this might be a tease but if Murray hasn't read it, then Murray hasn't written it, nor was he involved in writing it—so how good can it be? He added, "You know, the studio gets excited every 10 years or so. What they'd really like to do is recreate the franchise. I remember when the new Ghostbusters was going to be Chris Rock, Chris Farley and... someone."

A rumor in 2008 had Seth Rogan and Paul Rudd attached, and at that time Judd Apatow's production company was also rumored to be involved, but since then it's been refuted.

Whoever wrote the script on Murray's desk, he may never read it; when asked whether he thought it would be a bad idea, he responded, "I only made one sequel and it was Ghostbusters 2 and it didn’t end up the way it was presented”
