IDW has the current comic book run of Gohstbusters in which the original team has joined forces with the team from the recent reboot via interdimensional portals. During his panel at San Diego Comic-Con Ivan Reitman said the comic series is,
"very rich. And it gave me an idea for another [Ghostbusters] film."
Not just another film, but two other films. First Reitman discussed an animated film that would be told from the perspective of the ghosts. “
I think we have wonderful plans, [including] an animated feature that we’re deep in design on already… a really great story,” he
said.
“That’s going to surprise everybody, I think, when it comes out. And we’re dealing with Ghost World quite a lot. We’re looking at the film from a ghost point-of-view, and the Ghostbusters from a ghost point-of-view. I think that would be something very interesting.”
He then played to the crowd by adding, “
And of course a new live-action film.” Reitman went on to tease that the basis for the comic book, the two teams joining forces, could be the new live action film. “
It was clear a lot of people weren’t happy the original Ghostbusters world wasn’t included in the new one,” said Reitman.
“I love seeing [writer Erik Burnham’s take on] Kate McKinnon’s character’s interactions with Spengler [in the Ghostbusters 101 comic books]. It’s very rich, and has given me lots of ideas for a new film.”
It's unclear how a live action movie would unite the two teams, especially with the passing of Harold Ramis. Reitman also noted that the studio may try and tie one of the films releases with the 35th anniversary of Ghostusters in 2019.
