'Avatar' sequel delayed againLos Angeles, March 11 (AZINS) "Avatar" sequels have been put on hold again, says director James Cameron.

"Well, 2018 is not happening... We haven't announced a firm release date," Cameron said in an interview to The Toronto Star.

On why he needs more time for the movie's filming, he said: "What people have to understand is that this is a cadence of releases. So, we're not making 'Avatar 2', we're making Avatar 2, 3, 4, and 5. It's an epic undertaking. It's not unlike building the Three Gorges dam."

A new video game based on the 2009 sci-fi epic is being developed by Ubisoft, a company, which creates video game, in collaboration with Cameron's studio.

It is expected to "continue to expand and deepen in the 'Avatar' universe in exciting and innovative ways along with the films."
