Are you keenly anticipating the "Avatar" sequels? You're going to have to wait a little longer - two years longer than previously anticipated according to EntertainmentWise.
Speaking at a screening for "Titanic 3D", Producer Jon Landau confirmed it would be a good wait before we return to Pandora - "We are excitedly working on it as we speak and it will be four or so years before it will be out"
This would seem to push back the release of the second film to 2016, quite a jump from the December 2014 & 2015 dates for the two sequels that were previously being targeted.
Landau is confident however it'll be a better film than the first - "We are excited and we have a lot of the same team working with us, some great design and ideas and some great themes hopefully.”
