Avatar 2 To Start Filming Start In April

 Award winning Hollywood director, James Cameron is on course to begin production on his Avatar sequel trilogy this spring too.
20th Century Fox had formally delayed the project from its previous projected December 2017 release date (after Disney and Lucasfilm moved Star Wars: Episode VIII to that same month).

Currently, it appears that Avatar 2 in particular will start filming April 16th, around the same time that the cameras start rolling on the third Wolverine solo film and the next Alien movie alike.
It is confirmed that some cast members will be returning in the likes of Sam Worthington, Zoe Saldana, Stephen Lang, and Sigourney Weaver.
It has not been expalined how some of these cast members’ characters return, since details on the script that Cameron co-wrote with Rick Jaffa and Amanda Silver (Rise of the Planet of the Apes) remain firmly under wraps.
