"I think 'Avatar' works on DVD because of the storytelling, the characters and the vibrancy of the imagery," said Cameron. "I think that it's scaleable."
Cameron addressed the big question on a lot of moviegoers' minds: Will there be a sequel?
"I think we're going to do 'Avatar 2.' There's some things I gotta get worked out with the studio first," said Cameron.
And if you are not a fan of preview trailers on a DVD then you are in luck.
"That's my little gift to the DVD audience. I say, any time I make a billion dollars or more on a movie, you don't put any trailers at the head of it. We started that with 'Titanic,'" said Cameron.
"Avatar" will be released on DVD and Blu-ray on Earth Day, April 22.
