sry to say that weaver also has said that she would not be returning to do a third ghostbusters movie for the same reason that murray said he wouldnt return, that they both feel that they are older, as do i agree. plus you can only save the world so many times.

I feel that a Third Ghostbusters coming out right now although would be cool, would probably not be as glamourous as everyone's hoping.
For the guys to come back they would have to go through extensive exercise workouts, tons of hair dye, and lots of make up.
You can continue to hope….. but petitions, praying, and kissing up has not gotten this off of the ground. For it to come off the ground you would need a serious miracle. A million dollars to come floating down from the heavens oughto do it, but until then keep Ghostbusters III in your prayers.

ON a further note on MIB 2,
That was one of the worst movies EVER and was a disgrace to the MIB franchise. The reason it got money was people chose not to believe that it was a bad movie (which their friends said when they saw it), they went and saw it for themselves and found out that it was a bad movie.
