'Avatar' star Sigourney Weaver: '3D will be the future'

Sigourney Weaver has suggested that 2D filmmaking could soon become obsolete.

The Avatar actress said that as 3D technology improves, it may become the industry standard for all major feature films.

"I think 2D is going to be like black-and-white soon because 3D is the natural way that people encounter life, so it's a revolution the way that Greco-Roman sculpture was after hieroglyphics," she told The Independent.

"It's the future, but it will be a while before people can achieve 3D consistently in a way that puts you in a world of the story in a seamless way. That's the object: to immerse you in a world, not to trick you or entertain you.

"And that's why it's more important perhaps for a regular movie; you should be in their world - whatever they say and decide and think should mean more to you because you can't divorce yourself."

On reprising her role as Dr Grace Augustine in Avatar 2, Weaver added: "I'm excited to go back to Avatar. I know the story that James Cameron wants to tell is so much bigger."

The Avatar sequels will film back-to-back, with the first due to arrive in cinemas in 2014 at the earliest.
