The Vancouver International Film Festival (VIFF) is not known for its celebrities. It's not known for its glitz. It's not even known for its wild parties. It is known, however, for its diverse selection of films and an audience that is hungry for them. This year, the festival's slogan, ''Same Planet, Different Worlds," couldn't be more appropriate. VIFF takes us from Canada across the world on journey through thought-provoking, humorous, exotic, controversial and, sometimes, rather strange films. And judging by the packed theatres and long lineups of audiences trying their luck at being let into those sold-out shows, VIFF is a celebration of international cinema that audiences just can't pass up. But even for a relatively low-key festival, VIFF did have some interesting guests drop in. Attendees include Barry Pepper (The Snow Walker), Benjamin Ratner (Moving Malcolm), Elizabeth Berkley (Moving Malcolm), Deborah Kara Unger (Emile), Sarah Polley (My Life Without Me) Mark McKinney (The Saddest Music in the World), Robert LePage (Far Side of the Moon) and even the legendary Superhero creator Stan Lee who gave audiences a special treat at the Trade Forums this year.
