Bill Murray Describes "Ghostbusters III" as "My Nightmare."

Bill Murray - who was the first David Letterman guest ever on his original show 'Late Night with David Letterman; then returned as his first ever guest on 'The Late Show with David Letterman after his move to CBS; not-so-coincidentally was Dave's first guest tonight, on the evening Jay Leno returns to 'The Tonight Show' - dropped a nerd movie blogger bomb while chatting with Letterman this evening. Dave asked about the much-rumored Ghostbusters III, which Murray previously had mentioned in movie junkets that he'd be open to returning to.

This past December, while promoting a little movie called Avatar, Sigourney Weaver - who appeared in the first two Ghostbusters flicks - said she was willing to return, then mentioned that Bill Murray would be returning for the third entry "as a ghost." I didn't know what I thought about this, really, when I heard it, but I was at least pleased that Murray was willing to do a another installment. Murray himself confirmed the ghost thing in a recent interview with the Mail Online, but now it seems the tide has turned in terms of his willingness to return. When asked tonight by Letterman about Ghostbusters III, Murray described it as his "nightmare" then added "I told them if they killed me off in the first reel, I'd do it. So now they've figured out a way to kill me off in the first reel." Choosing the words "figured out" to describe killing him off indicates his character might be a mainstay in the movie just not as a living breathing character. It seems the work-around for a disinterested Bill Murray is to have him essentially cameo as Dr. Peter Venkman, kill him off then have the character remain in the movie as a ghost for the rest of the film a CGI character. Otherwise, why would they need to "figure out" a way to kill him off if there wasn't some creative twist involved? Maybe Murray - who had nothing but good things to say about lending his voice to the Ghostbusters video game - will do some voice-over work for his ghostly character instead of acting in the film in the traditional sense.

And it appears you can count Murray himself among those who agree. He did, after all, describe rumors of Ghostbusters III as "crazy talk" which doesn't bode will for its production; or at least his involvement.
