"Just out of nowhere, I get a phone call from Bill at almost three in the morning on Thursday and he simply said, 'Yeah, ok, Im in.' Thats Bill Murray for you. Surprising and straight to the point."Ghostbusters 3 is already in pre-production and was going to go ahead with or without Bill Murray. Murray was supposedly disenchanted with the idea of a third Ghostbusters outing after reading an early draft of the script last year. Up until now, it was looking likely that Reitman would be forced to push on without him. Ghostbusters 3 will star Bill Murray (Peter Venkman), Dan Aykroyd (Raymond Stantz), Harold Ramis (Egon Spengler) and Ernie Hudson (Winston Zeddemore) in a "passing of the torch" movie to a new generation of Ghostbusters. Sony Pictures hope to release Ghostbusters 3 at some point in 2014.
