Kristen Stewart heads 'On the Road'

Brazilian director Walter Salles has cast Kristen Stewart (‘The Twilight Saga' films, The Runaways) along with Sam Riley, Garrett Hedlund for the film adaptation of Jack Kerouac's 1957 seminal novel On the Road.

Salles directed The Motorcycle Diaries or Diários de Motocicleta with Gael Garcia Bernal portraying Che Guevara on a road trip with a friend.

To prepare for this much-anticipated project, Salles traveled across the US following Kerouac's footsteps and shooting a documentary. His Oscar-nominated writer on The Motorcycle Diaries, Jose Rivera, wrote this script.

Hedlund (Friday Night Lights, Tron Legacy) plays Dean Moriarty - based on Beat Generation icon Neal Cassady and Stewart plays his wife Mary Lou. Sam Riley (Control) plays Kerouac's alter ego, Sal Paradise, in the autobiographical tale.

The production begins filming this August for a planned release in 2011.
