James Cameron To Film Three Avatar Sequels At Same Time

James Cameron is to film three 'Avatar' sequels at the same time.

The 57-year-old director looks set to helm the hat-trick of movies after Sigourney Weaver, who is due to reprise her role as Dr. Grace Augustine for the follow up motion pictures to the 2009 3-D sci-fi film - which tells the tale of humans exploiting the natural resources of the planet Pandora - confirmed the plans are in her schedule.

In an interview with Showbiz 411, the 62-year-old actress admits she has no idea how James is going to helm all three movies at once, nor how long it will take before adding: ''I just show up.''

Sigourney's comments come after James - who has directed 'Titanic', 'The Terminator' and 'Aliens' - previously admitted he only plans to make 'Avatar' films for the rest of his career.

He explained: ''I'm in the 'Avatar' business. Period. That's it. I'm making 'Avatar 2', 'Avatar 3', maybe 'Avatar 4', and I'm not going to produce other people's movies for them.

''I'm not interested in taking scripts.... I think within the 'Avatar' landscape I can say everything I need to say that I think needs to be said, in terms of the state of the world and what I think we need to be doing about it. And doing it in an entertaining way.''
