We all know that Bill Murray is a serial prankster and the kind of guy who would probably take much joy from messing with our heads. BUT, if his reluctance to fully support 'Ghostbusters 3' (depending on his mood, he's either in or out of the picture) is still the reason why Columbia haven't yet managed to nail down a start date despite having a script they are keen on, then his appearance in costume (proton pack and all!) at last night's Spike TV Scream Awards, might be too sickening a joke for many fans to swallow. Either Murray's saying to us 'this is the closest you'll ever get to me as Peter Venkman again' or it's a message to the world that he's finally on board with the idea. Whatever the truth, it's certainly curious and I bet the first time he's appeared in full costume since the end of promotion on 'Ghostbusters 2' twenty years ago. A moment I never thought I would ever see again. See the full image below and let me know whether he could still get away with being a 'Ghostbuster' at 60 years of age..
