Trivia, insights & behind the scenes
This was the SECOND film adaptation of Gaston Leroux's 'Balaoo'—the 1913 original is lost, making this our only surviving glimpse of gorilla-head-swap cinema.
Released months before 'The Jazz Singer,' this represents silent horror's final gasp before talkies murdered the exaggerated physicality that made mad scientists iconic.
