This is the biggest talking point of all of the discussions and media hype around Ghostbusters 3. Is Bill in? Is Bill out? Almost every week something is definitely confirmed by someone. Some rumours say he randomly called Dan Aykroyd at 3.00am one night to say hes on board, others say that Bill actually shredded a copy of the script after he had finished reading it. But whatever the truth is, and even if he is eventually persuaded to be involved, its pretty obvious from all of the fuss so far that he doesnt want to be in the film. And that disinterest will become clear in the final product as, although Bill Murray is still an incredibly funny actor, he wont be giving it 100% for a film he never really wanted to do in the first place.
