On the Road has easily been one of the most anticipated films at this year's Cannes Film Festival -- it marks the first successful adaptation of the classic 1957Jack Kerouac novel of the same name. Directed by Walter Salles (The Motorcycle Diaries), the project began development in 2005. That same year, Kristen Stewart -- then 16 and a relative unknown -- was one of the first actors attached to the production. By the time On the Road finally began filming in 2010, Stewart was an international sensation with a hefty asking price. Yet despite a drastic pay cut and the demands of Twilight Saga schedule, Stewart remained committed to the film.
