'Avatar 2' shooting to begin this fall

Actor Sigourney Weaver says that the shooting for the much-awaited Avatar 2 is all set to begin in the fall of this year.

At a screening of The Assignment, the 67-year-old actor, who played Grace Augustine in the 2009 sci-fi film, says she is excited to start filming the second part of the James Cameron magnum opus soon, according to The Hollywood Reporter.

"We're starting training, and we're starting hmm, I probably can't say anything. We will be actually shooting it by the fall," says Weaver. She admits she is a little "worried" about turning such ambitious scripts into a reality on the screen, but says the sequel will not disappoint her fans.

"I'm telling you, these scripts are so amazing, I'm not worried about (disappointing fans) at all. Am I worried about how we're going to bring them to life? Yes, because they're so ambitious. They're so worth it. They're well worth waiting for. I'm not worried about that at all. We're trying to get it done as quickly as possible," the actor says.

Sam Worthington and Zoe Saldana will reprise their roles, alongside Weaver in Avatar 2.
