Re: Aykroyd Comments on Murray, Ghostbusters 3! Working on Script w/Ra
Given the nature of the franchise, Egon could always appear in a sequel. Use old footage and make him look ghostly. They could even use it as the catalyst for the start of the movie, the funeral for their friend.
And I wouldn't mind seeing Egon slime Bill Murray's character.
