Sci-Fi, Horror
A 1954 American science fiction film directed by W. Lee Wilder, brother of Billy Wilder. Peter Graves plays atomic scientist Doug Martin, who is presumed dead after his plane crashes on a reconnaissance flight following a nuclear test — then turns up alive, telling a story nobody believes: he was captured by aliens who plan to conquer Earth with an army of giant mutated insects and reptiles. Famous for its bug-eyed aliens (created with ping-pong balls) and liberal use of stock footage, the film features an uncredited early appearance by Coleman Francis. Its copyright was never renewed, and it has become a drive-in staple of public domain sci-fi collections.

Sci-Fi, Horror
A 1963 American science fiction horror film also known as Monstrosity, directed by Joseph V. Mascelli. A wealthy elderly woman, Mrs. March (Marjorie Eaton), funds the experiments of Dr. Otto Frank (Frank Gerstle), who uses an atomic reactor in her basement to transplant brains between bodies. Mrs. March wants her brain transplanted into the body of a beautiful young woman, and three European girls are lured to the mansion as candidates. The experiments go horribly wrong — one woman receives a cat's brain, another becomes a zombie — and the film culminates in the destruction of the laboratory. The film was shot in 1958 but not released until 1963 after the production company went bankrupt. It was later featured on Mystery Science Theater 3000.
