Launching us from a grave past to a space-age future, these two thrilling double features from producers Richard and Alex Gordon spin classic tales of hair-raising homicidal mania and intrepid, death-defying exploration. The Haunted Strangler: 19th-century English author James Rankin (Boris Karloff) believes that the wrong man was hanged twenty years earlier for a series of murders, yet in his investigations discovers a secret all-too-horrible and, for him, gruesomely inescapable. Corridors of Blood: In 1840s London, Dr. Thomas Bolton (Boris Karloff) dares to dream the unthinkable: to operate on patients without causing pain. Unfortunately, the road to general anesthesia is blocked by a local killer (Christopher Lee), as well as Bolton's devastating addiction to his own chemical experiments. The Atomic Submarine: When nuclear-powered submarine the Tiger Shark sets out to investigate a series of mysterious disappearances near the Arctic Circle, its fearless crew finds itself besieged by electrical storms, an Unidentified Floating Saucer, and lots of hairy tentacles. First Man into Space: In this interstellar cautionary tale, brash U.S. Navy test pilot Dan Prescott, hungry for fame, jettisons himself beyond Earth's atmosphere, only to come in contact with a hideously mutating extraterrestrial virus.
