“Ghostbusters 3” is in the works but it may not be similar to the “Ghostbusters” of yore that you knew. First, of course, Ivan Reitman will not be directing it. Second, Harold Ramis will not be in it due to the fact that he is not alive. Third, while Bill Murray is alive, he won’t be in it either due to the fact he has always said he will not participate in another Ghostbusters movie. That leaves only Dan Ackroyd and Ernie Hudson as possible Ghostbusters who could return for a final turn as Ghostbusters and also leaves Sony to hire Paul Feig [“Bridesmaids”] as director and turn the new Ghostbusters into females.
“Ghostbusters 3” – if it is actually made – would be expected to have a 2016 release date.
