Exciting if true
Good news, everybody! Whilst doing the press line at the National Board of Review's red carpet event, MTV's Josh Horowitz volleyed a series of Ghostbusters 3 questions off of producer Ivan Reitman and ended up getting a nice chunk of actual news instead of further conjecture. When asked about the script, Ivan confirmed that Lee Eisenberg and Gene Stupnitsky have already turned in a completed draft for part 3 and that a new draft is currently being worked through, much to the delight of all involved. When asked about a potential start date, Ivan revealed that he hopes to start shooting it within the next year.
Exciting if true
