Bill Murray was wearing a proton pack when he accepted the “Best Horror Movie” Award on behalf of Zombieland at the 2010 Scream Awards over the weekend. While he has previously stated that a third Ghostbusters film is a myth, according to IMDb, it’s really happening, with Murray joining original cast members Sigourney Weaver, Dan Aykroyd, Harold Ramis, Annie Potts, and Ernie Hudson. Perhaps this is a sign that Dr. Venkman has finally been won over? We can only hope. [via /Film]
