Sigourney Weaver says Avatar 2, 3 and 4 to start filming this fall . . .

Avatar is getting three – yes, count them, three sequels – according to actress Sigourney Weaver. In a recent interview the actress admitted that she doesn’t know how long it is going to take. “I just show up,” she said.

There has been recent talk on the Internet about James Cameron dropping hints that there will be a fourth Avatar movie and that the director won’t be making anything else besides Avatar sequels. (So no live action Battle Angel movie then.)

Producer Jon Landau also let drop recently that Avatar 2 maybe won’t make its initial 2014 release date.

However, if filming does star this autumn then the film might just make it to theaters by 2014. Avatar 3 is set for a 2015 release date and Avatar 4 is likely to hit cinemas in 2016.
