Fans of "Avatar" have been waiting for almost six years for the movie's sequel and unfortunately, it seems like they have to wait a little longer as reports indicate that "Avatar 2" is yet again delayed for another year.

Sources say that the original plan of the production was to release the film during the Christmas season of 2016, however, James Cameron, the director of the movie, decided to wait one more year.

Cameron reportedly decided to postpone the release date of "Avatar 2" because he is waiting for the necessary technology that allows underwater motion capture. The director wants to incorporate the deep depths of Pandora's ocean into his upcoming film.

Another supposed reason for the delay is Cameron's decision to finish off the scripts of not only one "Avatar" movie but two of the screenplays to complete the "Avatar" trilogy. The movies are expected to premiere consecutively from 2017 to 2019.

An interview by Entertainment Weekly with the film's musical director James Horner, who passed away a few months ago due to a plane crash, further revealed the reasons for delay.

"Right now Jim has four sequels, script wise. And he's trying to make it into three. And that is where, I think, his effort is going right now. To keep it to three sequels. Because he's got so much going on how do you keep it from expanding into a fifth movie, total. And he'll get that sorted out," said Horner.

In a separate sit-down, Cameron reassured fans that the upcoming movie would arrive sooner than later as the production would hasten because of all the new technology introduced.

"We expect to be able to accelerate the process quite a bit, because we've improved a lot of the software and the computer graphics tools, and we've been working very closely with Weta Digital down here in New Zealand developing a whole new suite of tools to speed up the process."

Currently, "Avatar 2" is scheduled to be released on Dec. 25, 2017.
