New updates have been released regarding the delay of James Cameron's award-winning sci-fi film "Avatar 2"20th Century Fox

Stephen Lang will reprise his role as the presumed-dead Colonel Miles Quaritch in "Avatar 2" and the three more films that will follow. While promoting his new horror thriller movie "Don't Breathe," the actor shared updates on the saga.

He revealed that he is almost done reading the scripts for all four films and added that production should begin next year. Lang also emphasized that tons of work on the "Avatar" films is being done as of the moment.

"We're getting there. We're in good shape. We'll be starting certainly early in the new year. But you know, the thing is, as you can imagine with a film like Avatar, it's not like the work hasn't been going on," Lang said.

"The design, the production design, the various worlds, and creatures and environments, that's all being worked on," he went on to say.

He revealed that apart from the story, which director James Cameron originally planned to be told in two films (now it doubled to four), work on "Avatar 2" has begun ever since the first one hit the cinemas and made blockbuster history.

Lang also had something to say about Cameron's efforts in putting together the mammoth of a chronicle. He said that the filmmaker "creates problems" that in turn requires him to come up with a technology that could make his idea work.

"I believe that's part of the quite perverse joy for him in this is creating these seemingly insurmountable problems, and then bringing aboard people who can be helpful and say, 'This is what we've got to do,'" Lang said.

He said that will all the work put in "Avatar 2" and the upcoming films, "it's going to be an absolute joy to behold."

"Avatar 2" is set for release in December 2018. "Avatar 3" will be out 2020. "Avatar 4" and "Avatar 5" will be out 2022 and 2023, respectively.
