Francis Ford Coppola has been working for 30 years to turn Jack Kerouac's seminal Beat Generation novel On the Road into a movie. It is starting to look like it was worth the wait. Amy Adams and Viggo Mortensen are joining the Walter Salles-directed adaptation that will begin this month, I'm told. She will play Jane, the emotionally damaged junkie mother of two children and the wife of Old Bull Lee. Mortensen is going to play Lee. Kirsten Dunst, Kristen Stewart, Sam Riley and Tron: Legacy's Garrett Hedlund are also set for the pic. Script's by Jose Rivera, who teamed with Salles on The Motorcycle Diaries. Coppola and Rebecca Yeldham are producing. The film began production today.
