A still from “On the Road.” (Mk2 Productions/Film4)

British actor Sam Riley stars as Sal Paradise, the narrator based on Kerouac himself, and “Tron: Legacy’s” Garrett Hedlund plays Dean Moriarty.

Also receiving top billing is “Twilight’s” Kristen Stewart, who plays Moriarty’s 16-year-old first wife Marylou. Will Stewart remove her bottom lip from in between her teeth and do the role justice? That remains to be seen. (The fact that her shirtlessness in the trailer is getting press bodes well for ticket sales.)

Those who love “On the Road” may be weary of any attempt to bring it the big screen. For what it’s worth, Kerouac — who was born 90 years ago today — wrote a letter to Marlon Brando in 1957 asking him to play Moriarty in a film. Brando, sadly, never replied.

One thing the film has going for it is Walter Salles, who directed another road story movie, “The Motorcycle Diaries.” It also boasts an impressive supporting cast, including Kirsten Dunst, Amy Adams, Elisabeth Moss and Terrence Howard.
