In a recent interview with Larry King, Dan Aykroyd discusses the details on "Ghostbusters 3," which is rumored to be directed by Ivan Reitman.
He described the plotline as "based upon new research that’s being done in particle physics by the young men and women at Columbia University… Basically there’s research being done that… I can say that the world… our dimension that we live in, our four planes of existence, length, height, width, and time, become threatened by some of the research that is being done. And ghostbusters, new ghostbusters, have to come and some the problem.”
When asked about Bill Murray 's reluctance to be in the new film, he said "there will definitely be a hole there for him if he decides he wants to walk back in."
"Ghostbusters" fans have been hearing about this third installment for years. We'll be keeping a close loko to see how this develops.
