So far, all of the surviving original Ghostbusters cast members — Bill Murray, Dan Aykroyd, Ernie Hudson, Sigourney Weaver and Annie Potts — have returned to make cameo appearances in the upcoming reboot. Everyone, that is, expect Rick Moranis. The actor who played Louis Tully in Ghostbusters and Ghostbusters II mostly retired from the public eye and hasn’t acted in a live-action feature since 1997, but revealed that he was approached to return for the Ghostbusters reboot and he swiftly turned them down.
