A roof top terrace in Cannes can be pretty nice on a bright if windy day. But it doesn't seem quite the right place for Gus Van Sant, whose habitat of choice is Portland, Oregon, ground zero of grunge and one of the wettest cities in the US. Portland is also where the director's latest film, Paranoid Park, a Rimbaud-like disquisition on disaffected youth, is set. Van Sant's house even puts in an appearance: a pleasant, unassuming villa separated from the sea by scrubland.
