Original Ghostbuster Harold Ramis tells The Chicago Tribune that talk of a third "Ghostbusters" last week is accurate:

"Yes, Columbia Pictures is developing a script for GB3 with my "Year One" writing partners, Lee Eisenberg and Gene Stupnitsky.

Judd Apatow is co-producing "Year One" and has made several other films for Sony, so of course the studio is hoping to tap into some of the same acting talent.

Dan Aykroyd, Ivan Reitman and I are consulting at this point, and according to Dan, Bill Murray is willing to be involved on some level. He did record his dialogue for the new Ghostbusters video game, as did Danny and I, and Ernie Hudson.

The concept is that the old ghostbusters would appear in the film in some mentor capacity."
