Frozen Alive (aka) Der Fall X 701 is a 1964 British-German international co-production science-fiction film produced by Artur Brauner and Ronald Rieti, and directed by Bernard Knowles. It stars Mark Stevens, Marianne Koch, and Wolfgang Lukschy. The film was released in the US in 1966 on a double bill with Destination Inner Space.

The plot concerns scientists Dr. Frank Overton and Dr. Helen Wieland, who are experimenting in Berlin with "deep-freezing" chimpanzees (the word cryogenics is only used once in the film) and thawing them unhurt. Overton decides to use himself as a human test subject, but he is wrongly accused of murdering his philandering wife, and the police believe that he is attempting to avoid arrest.
