The Glass Cage

Like a 1950s David Blaine, The Great Sepolio starves in a glass tomb while a murderer is on the loose.

The Greatest Enigma of All Time tries to break his record for going without food in this Hammer thriller set against the backdrop of postwar London. But the murder of a young woman sets the carnival community on edge and the death toll rises until the culprit makes his fatal mistake. Tense and well-acted, this British B-movie packs plenty of nerve-jangling moments into its 58 minutes.
