Avatar 2 & 3 may be filmed back-to-back

[Raptor]

“We’re actually talking about [doing 2 and 3] back to back. That’s not a decision yet but that’s something that makes a lot of sense given the nature of these productions because we can bank all the capture and go back and do cameras over a period of time… cause the way these sort of back to back productions fall apart is you’re trying to do two live-action films back to back and you’re working on it for like a year and a half shooting. Everybody’s dead- it’s not humanly possible. But this type of film it absolutely would work.”
