Trivia, insights & behind the scenes
This was the first screen adaptation of Gaston Leroux's 1907 novel—the same dude who wrote Phantom of the Opera. Dude LOVED a mystery.
The 'locked room mystery' basically INVENTED detective fiction as we know it, and this film is grandpa to every Knives Out twist you screamed at.
