Chris Pontius going 'Somewhere'

'Jackass' co-star cast in Sofia Coppola film

Chris Pontius has booked a room in Sofia Coppola's "Somewhere."

The "Jackass" trouper will play Sammy, best friend of the character played by Stephen Dorff, a decadent, bad-boy actor living at the Chateau Marmont in West Hollywood who begins to re-examine his life after a surprise visit from his 11-year-old daughter (Elle Fanning).

Coppola, who wrote, directed and produced "Marie Antoinette" and "Lost in Translation," is doing the same for "Somewhere." Francis Ford Coppola, Fred Roos and Paul Rassam are executive producers on the American Zoetrope/Focus Features production.

Pontius, repped by Gersh and Untitled Entertainment, had roles in "Charlie's Angels: Full Throttle" and "What We Do Is Secret."
