Both Sam Worthington and Zoe Saldana will return to Pandora for the Avatar sequels it was confirmed yesterday.
It was obviously going to happen as they were the leads in the original mega-hit Avatar, but now we have confirmation that both Sam Worthington and Zoe Saldana will reprise their roles for the three sequels. 
James Cameron is currently prepping to shoot three films back-to-back in New Zealand, much like what Peter Jackson did with his The Lord of the Rings and The Hobbit movies.
The first sequel is set to be unleashed onto cinemas in December 2016. Could it surpass its predecessor? That remains to be seen.
