GB3 will actually be a movie. I read that Dan Aykroyd and Harold Ramis are actually in the process of writing GB3. Aykroyed and Ramis will play their original parts of Ray and Egon. Ernie Hudson has agreed to return as Winston Zedmore. Last I heard was that they were still talking to Bill Murray about playing Peter again, but oh yes GB3 will be a movie and a great one at that.
