Two movie trends have converged and brought us a project that had been rumored for years that almost no one thought would actually happen.

Right now, remaking '80s comedies is hot ([url id="http://moviesblog.mtv.com/2009/03/16/russell-brands-arthur-remake-will-honor-boozy-original-with-new-york-setting-burt-bacharach-tunes/"]"Arthur"[/url] and [url id="http://moviesblog.mtv.com/2009/02/10/exclusive-brett-ratner-promises-hard-r-in-reinvention-of-bevery-hills-cop/"]"Beverly Hills Cop"[/url]) and anything supernatural is really hot ("Twilight" and, uh, "Twilight"). To capitalize on these trends -- or maybe just because it's not fair to deny longtime fans any longer -- Columbia Pictures announced that a third "Ghostbusters" movie is in the works, two decades after the last one came out.

Earlier this week, Harold Ramis stopped by MTV News to chat about his new Jack Black comedy [url id="http://www.mtv.com/movies/movie/349805/moviemain.jhtml"]"The Year One"[/url] (in theaters June 19). But we also asked Ramis -- who co-wrote the first two "Ghostbusters" movies and, of course, starred in them as uptight-but-lovable Dr. Egon Spengler -- to dish details on the upcoming reboot.

Ramis promised that all the old core players will take part in the updated version, including Bill Murray (Dr. Peter Venkman) and Dan Aykroyd (Dr. Raymond Stantz), who co-wrote the original films. "We're all going to be in it in different kinds of roles," Ramis said. "We're going to be the sage mentors. There are going to be young Ghostbusters."

As of now, no decisions have been made about just who those new Ghostbusters will be. But with Judd Apatow signed on as a producer, the Internet has been buzzing with gossip that comedians from his cinematic universe, such as [url id="http://moviesblog.mtv.com/2008/11/06/role-models-star-paul-rudd-denies-ghostbusters-casting-during-exclusive-stuffed-animal-booth-interview/"]Paul Rudd[/url] and Seth Rogen, will join in.

At the moment, Ramis is waiting on a first draft of the script, which is being penned by Lee Eisenberg and Gene Stupnitsky, two writer/producers on "The Office," who also wrote "Year One." "Gene and Lee, both of whom I mentored, are now writing the new 'Ghostbusters,' " Ramis said. "I'm consulting with them, as is Dan Aykroyd and [original director] Ivan Reitman.

"Bill Murray is just waiting for the truckload of money to arrive to get him out of his office," Ramis joked.

After taking a jab at his old friend, Ramis assured us that Murray is definitely "in," even though the two haven't communicated directly about the project. "I haven't talked to him about it," Ramis said. "I want to talk to him about it eventually. I think we just need a script, because he's the thorniest of the group."

Another open question is who will take over directing duties, since neither Ramis nor Reitman is planning on helming the picture. "I'm sure we're all hoping someone else will do it," the 64-year-old Ramis said. "It's a lot of work!"

While we await casting and directing news, Ramis was able to shoot down gossip about certain stars once thought to be attached to a third "Ghostbusters." "Here's how old the rumors are," Ramis said. "Chris Farley was one of the rumors. It was going to be Chris Farley, Ben Stiller and Chris Rock."

Whichever actors end up portraying the fresh crew of wisecracking ghost fighters will be in for a challenge. "Someone asked Seth [Rogen], and he said, 'What?' " Ramis recalled. "He said, 'That'd have to be one great f---ing script for anyone to touch that.' He's right about that."
