The film opens with a high-stakes armored car robbery on London’s —a sequence noted by reviewers for its impressive, nearly silent execution. When a member of the gang is murdered by a throwing knife, the investigation leads Inspector Elliott (Leo Genn) to the winter quarters of Barberini's circus.
A menacing, hooded lion tamer with a mysterious past.
The circus provides a rich, "fog-soaked" backdrop filled with suspicious characters, including:
“The cast is headed by Christopher Lee who is grim and imposing... the film presents a lot of suspects and it soon becomes easier to just watch it rather than try and guess who the killer is.” IMDb
remains a solid recommendation for fans of 1960s British thrillers and those who enjoy seeing cult cinema legends sharing the screen in a gothic circus setting. Psycho-Circus (1966) - IMDb
