This is assuming all the pieces are now in place, especially Bill Murray who has had very little good to say about the project. Ivan Reitman will likely be back to direct, along with Dan Akroyd(who might've rewritten the script), Harold Ramis, Rick Moranis, Sigourney Weaver, and the other guy. The "tell him about the Twinkie" guy. Oh yeah, Ernie Hudson.
