Twenty years after the release of Ghostbusters II, the original cast will reunite for a second sequel to the 1984 classic. Ghostbusters 3 could be in production as early as winter, said Dan Aykroyd, who confirmed that original cast members Sigourney Weaver, Bill Murray, Harold Ramis and Ernie Hudson are on board for the project. The script is by Lee Eisenberg and Gene Stupnitsky, the writing team behind the upcoming Jack Black/Michael Cera movie Year One. Not surprisingly, the premise of the movie will be a new generation of Ghostbusters taking over the duties of the aging team. “I'd like it to be a passing-of-the-torch movie”, said Aykrod. “Let's revisit the old characters briefly and happily and have them there as family but let's pass it on to a new generation.” The details of story have not been decided, but Aykroyd is hoping the new team will include several female members.
