Speaking to US Radio DJ Howard Stern this week, Bill Murray has reiterated the reasoning behind the long wait for the Ghostbusters' third big-screen outing - and it is of course, is himself. For those of you who have kept an ear to the door throughout this whole saga, this news will come as no surprise, what with Murray's clear disapproval of rebooting the series that has been MIA since the much-maligned Ghostbusters 2. Speaking again of the lamentable sequel, Murray said that it "didn't end up the way it was presented" but that " wants to make it (Ghostbusters 3) and I owe him." Clearly less than thrilled at the thought of returning to the role of Dr Peter Venkman, Murray seems to be considering his possible return to the series as a favour to Reitman, rather than as a personal project. "He's puzzled that I haven't gotten to this one" - he said of the Director's reaction to his nonchalance - "I'll get to it. I feel bad. I got a message and I think people - I don't want to hurt anyone's feelings - it's not the foremost thing in my mind, so I don't think about it." The black cloud continues to loom heavily over this one, and it remains to be seen whether whether the tumultuous build-up to the official announcement of the sequel will reflect upon the quality of the final product. With both original 'busters Dan Ackroyd and Harold Ramis on board there is a glimmer of a silver lining, but it goes without saying that Murray was always the main attraction. Without his A-OK, this is just another idea that should never have left the board room.
