New 'On The Road' Trailer: Kristen Stewart's Not Playing Bella In This One (VIDEO)

On the eve of Kristen Stewart's final "Twilight" bow, IFC released a new trailer for the movie with her next appearance, "On the Road."

An adaptation of the celebrated novel by Jack Kerouac, "On the Road" shows a whole lot more of Stewart than was ever seen in "Twilight" -- the actress appears naked multiple times and is shown performing sex acts on two men at once, in a moving car.

"I wanted to do it" Stewart said at Cannes. "I love pushing, I love scaring myself."

Produced by Francis Ford Coppola ("The Godfather") and directed by Walter Salles ("The Motorcycle Diaries"), "On the Road" premiered at Cannes and TIFF to mixed reviews.

The movie stars Sam Riley as Sal Paradise, Garrett Hedlund as Dean Moriarty, and features Kristen Dunst, Viggo Mortensen, and Elisabeth Moss, in addition to Kristen Stewart.

"On the Road" is due out in theaters Dec. 21.
