Jessica Alba and Hayden Christensen have stepped out on the red carpet in New York to promote their new film Awake.

In the film, Christensen plays a young man who's perfect life is a lot darker than it seems.

His fiancee (Jessica Alba) is employed by his overbearing mother, and he's in desperate need of a heart transplant.

Alba, who's starred in Fantastic Four and Sin City, said she was partly attracted to the film because it was a break from all the commercial films she's been working on

She said: "A big reason why I wanted to do this movie is it's an independent shooting in New York; it's about my relationship with Hayden.

"I got to play it exactly the way I wanted to, a person with emotions and inner struggle and all of that fun stuff that actors like to do."

Awake is released nationwide on February 29.
