Composed primarily of shapes and lights, the scene might be an art-house version of the whirlpool-like "Hypno-Vista" gimmick that opens "Horrors of the Black Museum" (1959), or the "Hypnomagic" process of " The Hypnotic Eye " (1960).
Two of their previous films, Horrors of the Black Museum (1959) and Circus of Horrors (1959) had explored the same areas as Peeping Tom would - the voyeuristic appetite for violence.
