Query: CULT FAVOURITE

This grim and morose film has strong undertones of sadism and toward the end, brutality. The most dangerous game is man. This genuinely frightening film has Banks cast as a mad Russian Count who lives on strange little island and literally waits for ships to wreck on the dangerous reef along his sinister domain.....I'll not give anymore of the plot away except to say originally, there were to be scenes of decapitated heads which were later thought to be too upsetting to viewers. The atmosphere of the film is really creepy: both the black evil-looking castle and primeval forests on the island are terrific. The dark theme of this movie would be repeated in countless films and radio shows to say nothing of television.
