Cameron 'wants underwater Avatar sequel'

James Cameron has said that he wants to capture his sequel to Avatar underwater.

The second instalment will centre on the exploration of the oceans of Pandora, which the director described as "equally rich and diverse and crazy and imaginative" as the first film's setting.

"I think what we should do there is - because we'll have to have characters that are in and under the water - is that we should actually capture them underwater," he told MTV News.

"It's not the same as going diving, but I like to keep my diving, which I do for pleasure, separate from work."

He added: "Diving for shooting a movie is work. Diving for exploration is a gas. I like to keep my peas and carrots separate."

Cameron recently suggested that he may film the franchise's second and third films back to back.
