Sam Worthington says James Cameron will start shooting ‘Avatar 2’ in October 2014

Eagerly-anticipated sequel is scheduled for release in December 2016

Sam Worthington has said that production on Avatar 2 will finally begin in October 2014 – around 12 months from now.

Worthington, who starred as Jake Sully in the original 2009 film, revealed the sequel’s start date during an interview on Sydney-based radio station Nova 96.9. He went on to explain that Avatar 3 and Avatar 4 will be shot immediately after Avatar 2, with the entire filming process expected to last about a year.

Director James Cameron confirmed in August that he is now working on not two but three Avatar sequels. Avatar 2 is scheduled for release in December 2016 with the third and fourth films set to follow in 2017 and 2018.

Released in 2009, Cameron’s Avatar became the highest-grossing movie of all-time, a title it still holds, with worldwide box office takings exceeding $2.7 billion (£1.7 billion). Worthington’s co-stars in the original, Zoe Saldana and Sigourney Weaver, are also expected to return for the sequels.

Meanwhile, it was reported last month (September) that Arnold Schwarzenegger is being lined up to join the cast for Avatar 2 and will play a “bad guy human general”. Cameron has yet to confirm this but he has worked with the Austrian actor on three previous films: Terminator, Terminator 2 and True Lies.
