During an episode of The Big Interview with Dan Rather, Dan Aykroyd more or less confirmed that another installment of the classic Ghostbusters franchise is in the works. Aykroyd said that he was working on a screenplay for the possible film and that the much of the original cast would return.
“There is a possibility of a reunion with the three remaining Ghostbusters,” said Aykroyd, according to a report by Unilad. “It’s being written right now. I think Billy will come. The story’s so good. Even if he plays a ghost.”
An old rumor suggested that the third film would concentrate on Oscar, the lovechild of Dana, played by Sigourney Weaver, and Peter Venkman, played by Bill Murray. In the rumored version of the story, Oscar has taken over the business after the death of his father, which is featured as the opening scene.
If the rumor is true, that could explain why Aykroyd mentioned Murray being a ghost in the film.
Previously, a third Ghostbusters installment was greenlit. However, the illness and subsequent death of Harold Ramis, the actor who played Egon Spengler in the other two films, impacted the plan.
Aykroyd and Ramis scripted the first Ghostbusters, a take on Aykroyd’s original idea for “Ghostmashers” which would have featured him and John Belushi hopping from one dimension to another in an effort to battle ghosts.
When Ivan Reitman, the director, saw the script for “Ghostmashers,” he had concerns regarding the budget requirements. He urged Aykroyd to work with Ramis in an effort to scale certain aspects back to make the film affordable.
Ultimately, they developed the story for Ghostbusters, featuring the team of parapsychologists who begin fighting ghosts after losing their jobs at Columbia University.
