Rumors have been circulating that a third Ghostbusters movie is going to be made with the original castmembers Harold Ramis, Bill Murray, Dan Aykroyd and Ernie Hudson. Pajiba has a good summation of the rumors leading up to last Friday. And IGN reports:

Columbia Pictures has tapped the Emmy-nominated writing team of Lee Eisenberg and Gene Stupnitsky (co-executive producers of The Office) to pen the screenplay.

Now Harold Ramis has respoded to the rumors in an email to The Chicago Tribune:

yes, columbia is developing a script for GB3 with my year one writing partners, gene stupnitsky and lee eisenberg.  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. 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.  not much else to say at this point.  everyone is confident a decent script can be written and i guess we’ll take it from there.
best,
harold

Looks like Harold went the the Tarantino grammar school.
