With a vast majority of the franchise's original cast expected to/committed to return for a third GHOSTBUSTERS film in one way or another, it should come as no surprise that GHOSTBUSTERS 1 & 2 producer /director Ivan Reitman is also "100%" confirmed to be on-board. Word of Reitman's potential proximity to this movie was floated by MTV A FEW MONTHS AGO (were they the first to report it?)
