Watch the On The Road trailer online now

On The Road has been cruising through production for some time now, and finally a trailer has arrived, which you can watch online below.

The film is an adaptation of the cult beat novel by esteemed travel writer Jack Kerouac, which was written in 1951 and published later that decade.

The characters are interpreted as barely disguised versions of Kerouac and his buddies, with Sal Paradise (Sam Riley) and Dean Moriarty (Garrett Hedlund) standing in for Kerouac and Neil Cassady.

Kristen Stewart joins the boys for the ride as Marylou, in another role that looks set to further prove that there's more to her than Bella Swann.

The supporting cast of characters is teeming with star names, including Viggo Mortensen, Amy Adams, Kirsten Dunst and Mad Men 's Elisabeth Moss, who all get a small amount of screentime in the trailer.

This brief glimpse suggests that Walter Salles' ( The Motorcycle Diaries ) movie will have captured the free-wheeling spirit of the novel, and the open highways drenched in hazy sun demand to be gawped at.
