Battlefield Earth

(Warner Home Video)

Most of the extras on this L. Ron Hubbard-inspired sci-fi fantasy amount to little more than throwaway promotional material. But director Roger Christian's commentary — much like the film itself — is so bizarre and incoherent that it must be experienced to be believed. Among the more perplexing revelations: John Travolta's bad guy was "modeled on English kings from Shakespeare," and the director considers this bloated debacle "an independent little film."
