Sea of Shadows

Winner of the Audience Award in the World Cinema/Documentary competition at this year's Sundance Film Festival, Sea of Shadows comes off as a suspenseful documentary about the heroic efforts to save the vaquita porpoise from extinction. Found mostly in the Gulf of California, the vaquita is the world's smallest whale and most endangered sea mammal, and there may be fewer than 15 left. The movie screens at 9:20 tonight and at 6:30 tomorrow night at the Cleveland Institute of Art Cinematheque. Tickets cost $10, or $7 for Cinematheque members and students. (Niesel)
