Its not what you think. Or rather, it is what you think, but its not presented how you would expect. Robinson Devors film Zoo is indeed the true story of a Washington man who died from a perforated colon, an injury he received while being anally penetrated by a horse. But Devor made neither a straight documentary of the facts, nor a lurid, sensationalized exploitation of the incident. Fascinated by the life of the deceased Mr. Hands, a seemingly normal Boeing engineer named Kenneth Pinyan, Devor crafted a feature that delves into the internal and external forces that moved Pinyan and his cohorts into the secretive world of zoophilia -- without displaying any interspecies sexual acts, despite the zoophiles' predilection for videotaping every encounter. Using audio-only interviews of the men who were with Pinyan that fateful night, non-explicit re-creations of key events and a poetic cinematography that underlines the zoo's isolation from the normal world, Devor humanizes people engaged in what most of us would deem unthinkable acts. We are not who we appear to be, the movies tagline, refers to the secretive zoo subculture and to humanity as a whole.
