On The Road - Jack Kerouac's free-form novel, first mooted as a movie in 1957 - has had a long and twisted path to the big screen.
We explore the fascinating story of its wild trip to cinemas in our October issue of Total Film (on-sale now!) , interviewing all the key people involved in finally bringing the classic novel to your local popcorn emporium.
As part of that exploration, we spoke to Garrett Hedlund as he prepares to leave behind one cinematic car to clamber into another for the Coen brothers.
Tell us about filming Inside Llewyn Davis for the Coen brothers?
"It's a wonderful story loosely based on this struggling folk singer in the sixties named Dave Von Ronk. It's a wonderful cast and a wonderful period. My part was just me and John Goodman and my buddy Oscar Isaacs in a car, so I don't know what the rest of the film is going to be like – but I sure got a kick out of filming.
"The Coen brothers, they're two of the greatest. Those guys are two of the wisest, smartest, most brilliant filmmakers in the world and I would have played a Bellhop in the elevator for them, I would have been extra No.10 at a dinner scene to work with them."
On The Road opens on 12 October 2012.
