LOS ANGELES — James Cameron offers what may be the most exotic planet full of aliens ever put on film in his sci-fi epic "Avatar."
Yet if and when humans do meet creatures from other worlds, they'll be unimaginably more far-out than anything Hollywood can dream up, Cameron said.
"It'll be much beyond what we can imagine," said Cameron, whose "Avatar" opened big this weekend with $232 million worldwide. "There are creatures right on Earth that are absolutely amazing, and all the aliens are already here, if you look at a small-enough scale or you look under the ocean."
