The 20-year-old actress will start filming in August. For the movie, Stewart will play Mary Lou, the on-again, off-again wife of Dean Moriarty ... a character based on Neal Cassady from the Beat Generation.

Director Walter Salles has been writing the On the Road adaptation for years, even filming a documentary while traveling the word and tracing the footsteps of Kerouac. As for Kerouac's novel, it was first published back in 1957 and has since sold millions of copies.
