Watch Rhinoceros

"Rhinoceros" (1974) is an American comedy based on the absurdist Eugène Ionesco play of the same name. In it, people in a large town are inexplicably turning into rhinos. The victims of the bizarre transformations include the protagonist's best friend and girl friend, while he remains human. The protagonist is at first detached and bemused, but he becomes increasingly upset as people close to him fall victim to the strange metamorphosis.
