Circus of Fear

"Based on an Edgar Wallace murder mystery this chiller centers on a Scotland Yard investigation of a series of puzzling deaths plaguing a traveling circus and the hunt for loot stolen from an armored car robbery. Suspects include the mask-wearing and disfigured lion tamer, a vengeful ringmaster, an insanely jealous knife-thrower, and a blackmailing dwarf called ""Mr. Big."" The film is also known as Circus of Fear. A German version was shot simultaneously with Psycho-Circus but used a different director. Though available in color in Great Britain, most of the American copies of the film are in black-and-white."
