When you were reading old Jack Kerouac's "voice of a generation" novel, did you picture heartthrobby dreamboat Garrett Hedlund as Dean Moriarty? Yes? Well, today is your lucky day. After getting a first look at the movie about a year ago, we now have the trailer. Sam Riley stars as Sal Paradise (the narrator, based on Kerouac himself) and Kristen Stewart plays Mary Lou, the one whom Kerouac described thusly:

Marylou was a pretty blonde with immense ringlets of hair like a sea of golden tresses; she sat there on the edge of the couch with her hands hanging in her lap and her smoky blue country eyes fixed in a wide stare because she was in an evil gray New York pad that she'd heard about back West, and waiting like a longbodied emaciated Modigliani surrealist woman in a serious room. But, outside of being a sweet little girl, she was awfully dumb and capable of doing horrible things.

And then there's Hedlund, whom you may remember as Brad Pitt's golden boy, Patroclus, in Troy. He also played Don Billingsley in Friday Night Lights and Beau in Country Strong and has a certain stomach-fluttery je ne sais quoi.

Although some said the stills we saw last year looked like they were from an Urban Outfitters catalog, all in all, the trailer has a great rhythm, and since Walter Salles — who made another gorgeous road picture, The Motorcycle Diaries — is the director, things might just turn out okay. Keep your eyes peeled for Kirsten Dunst, baby-wipes enthusiast Terrence Howard, Amy Adams, Elisabeth Moss and Viggo Mortensen, who also make brief appearances in this clip.
