The pair have been keen to work together again ever since Cameron helped turn Alba into a star, and now she's convinced he has found the perfect part for her.
She tells movie website IGNFILMFORCE.COM that Cameron has always been keen for her to headline an underwater adventure called FATHOM.
She says, "Jim Cameron has been kind of talking about maybe doing a comic book that involves scuba diving, it's sort of like this girl underwater, and I have been talking about doing something like that.
"It was just something that he sort of liked. We talk about a lot of things. I just thought that, I didn't scuba dive for seven years and I should brush up on it."
Fathom, which is based on a TOP COW comic, was first announced in 2002. It had been previously set up as an animated film.
