Amy Adams and Viggo Mortensen have boarded the Walter Salles-directed adaptation On the Road, joining Kristen Stewart and Kirsten Dunst, according to Deadline New York.

Francis Ford Coppola has been working for 30 years to turn Jack Kerouac's seminal Beat Generation novel On the Road into a movie.

Adams will play Jane, the emotionally damaged junkie mother of two children and the wife of Old Bull Lee. Mortensen is going to play Lee.

The film began production today.
