John Oliver, star of The Love Guru, bares all in this provocative new documentary from a director who has heard of Fritz Lang. A cast of grotesques that includes a Sophoclean chorus in the form of a live studio audience, and a stern scientist/ father figure combine to torment the titular character in a dark carnival of self-discovery. Will Oliver face up to his latent homolateralism? Will Ahmadinejad finally finish off the ghost of Zaltzman? Find out, in this exciting conclusion to the "Godfather" tetralogy.
