G. I. Joe is a movie franchise that doesn't seem to have taken off quite the same way other summer tentpoles have, but worldwide grosses for both G. I. Joe: The Rise of Cobra and follow-up G. I. Joe: Retaliation both did well enough that a third installment will be coming our way at some point.
Collider spoke to franchise producer Lorenzo di Bonaventura, who is also behind Transformers and other big action franchises, and who says GI Joe 3 is on track to start filming in early 2015.
They're currently negotiating with their chosen screenwriter, says the producer, who adds this about the vague production timeline:
G.I. Joe 3 we are trying to get going, starting early next year…I think it'll be a little later than [January]. I think February or March is probably more realistic. We were originally shooting for January and I think it's slid a little bit, but you never know. It's still a little too early to tell yet.
Meanwhile, John M. Chu is definitely not returning to direct the threequel, and the producers are now starting to meet wit potential replacements:
We're just starting [to talk to directors]. We're negotiating with a writer right now, and once we close that deal—which should be any moment—then we'll have a story locked down. I'm really excited about it.
And on the casting front, Dwayne Johnson will definitely be back as Roadblock, but he's not sure which other characters will be reprised or added:
One thing is for sure: there were some characters the fans were really shouting for us to put in, we're gonna put in a few one of the ones that they know that would be new to the movie audience if they don't know the mythology.
