Deep Dive

Trivia, insights & behind the scenes

Cultural

1920 audiences were obsessed with hypnosis scandals; this rode the wave of real 'mind control' panics in popular press.

Trivia

Henry King would become one of Hollywood's most prolific directors, but this early experiment in subjective camera work during trance scenes nearly got him fired.
