Sequels
A script for a potential third film was under development by Gene Stupnitsky and Lee Eisenberg, the writing team that worked with Harold Ramis on the 2009 comedy Year One; according to Ramis, the four main cast members from the original film may have minor on-screen roles: "The concept is that the old Ghostbusters would appear in the film in some mentor capacity". Comments from Murray in August 2010, after Year One's release suggested the latter's poor reception made a new Ghostbuster sequel a "dream just vaporized." Two months later, Aykroyd downplayed Murray's comments, saying Stupnitsky and Eisenberg "wrote Bill the comic role of a lifetime, and the new Ghostbusters and the old are all well represented in it"; they wrote a "strong first draft" that Aykroyd and Ramis would work on. In February 2012, Aykroyd said "The script must be perfect. We cannot release a film that is any less than that. We have more work to do."
