Plan 9 from Outer Space (originally titled Grave Robbers from Outer Space, or simply known as Plan 9) is a 1959 American science fiction thriller film written and directed by Ed Wood and released by Distributors Corporation of America (as Valiant Pictures). The film stars Gregory Walcott, Mona McKinnon, Tor Johnson and Maila "Vampira" Nurmi. The film bills Bela Lugosi posthumously as a star, although silent footage of the actor had been shot by Wood for other, unfinished projects just before Lugosi's death in 1956.
