Robert Pattinson may not have fangs, but he's still brooding in the trailer for his upcoming film, Remember Me!

In the first TV spot for the flick, the Twilight star, 23, plays a rebel who falls for Lost's Emilie de Ravin.

In one scene, he picks up Ravin, 28, and carries her into bed with him.

"Someone tried to tell me, 'Make her yours forever," he says in the trailer, which premiered on before it hit airwaves. "I'm working on the forever part."

Pattinson reportedly had a brief fling with the actress when they spent the summer in New York City shooting their movie -- and lots of makeout scenes! Although Ravin and husband Josh Janowicz had been considering divorce (unrelated to her sexy new costar), they have since reconciled.

Remember Me opens nationwide March 12.
