If you have been an avid 'Ghostbusters' fan, you probably know that the plot revolves around catching ghosts and trapping them in a vacuum-like machine. However, producer Ivan Reitman aims for 'Ghostbuster III' to involve a little more than that.

He confirmed with Toronto Life that 'Ghostbusters III' is no longer just a rumor, but an actual film that is in the works.

"The studio is in, and we have writers working on it as we speak. We're ­hoping to film at the beginning of next year. Dan Aykroyd and I meet about once a month to talk about it" he said.

He also said that Bill Murray publicly declined working on the movie, but he still has hopes that he will join in considering that they "have done six movies together, and he never says yes until literally just before the shoot."

"I told him, 'I don't care if you do ­Ghostbusters-I mean, I'd love it if you did-but why aren't you doing leading parts for big studio films?' He said he didn't want that responsibility. He wanted to be a character actor," Reitman added.

It is also reported that the film will have a female lead, even though the original series only had male stars.

The female lead is Dr. Anna, and according to the Ghostbusters Blog, she is "a few years older (in her 30s?) and like the original Ghostbusters, is a real doctor."

The film is expected to hit the theaters next year.
