Variety.com said the project being penned by Lee Eisenberg and Gene Stupnitsky would ideally reunite Harold Ramis, Bill Murray, Dan Aykroyd and Ernie Hudson, the stars of the first two installments. However, the studio doesn't plan to make any deals with the actors until it has a script in hand, the entertainment industry trade newspaper said.

Hudson, who recently lent his voice to a video game based on the 1980s paranormal comedies, told UPI in December 2007 that he was up for doing a third movie.

"Dan Aykroyd and Harold Ramis, I know they want to do another film," Hudson said. "It would be great if we could get back together again."

Ivan Reitman, the director of the first two movies, told UPI in July 2006: "What makes me nostalgic for 'Ghostbusters' is to work with Bill Murray, Dan Aykroyd and Harold Ramis; that was the joy of working on 'Ghostbusters' and 'Ghostbusters II.' They've become old friends. That's what you miss. It's not staging a marshmallow man walking down Columbus Circle; that's a pain in the ass. It's much better getting (the actors) all in a room and doing something funny."
