Ghostbusters 3 is A GO!

Seems like Bill Murray is indeed doing "GHOSTBUSTERS 3" co-star Harold Ramis said he got a call from Bill @ 3am in the morning...and he simply said "yeah , OK I'm in"

That means the three main ghostbusters....Murray, Ramis and Aykroid are all on board. Theres no word yet on Ernie Hudson or when production will start
