Random Trivia For This Title:
- This is the first film directed by Alfred Hitchcock in which he makes one of his trademark cameo appearances. The cameo as an extra came by accident when he didn't have enough people for extras in a scene, he decided to help by appearing in the scene himself. As a result, he decided to turn his appearance into one of his trademarks with him performing silent walk-on bits in most of his later films appearing as uncredited extras.
- Ivor Novello reprised his role in the 1932 sound remake of The Phantom Fiend, directed by Maurice Elvey. Hitchcock was asked to serve as director for the remake, but declined. The 1932 film was released in the United States as "The Phantom Fiend."
- For the opening of the film, Alfred Hitchcock wanted to show the Avenger's murder victim being dragged out of the Thames River at night with the Charing Cross Bridge in the background. But Scotland Yard refused his request to film at the bridge. Hitchcock repeated his request several times, until Scotland Yard notified him that they would "look the other way" if he could do the filming in one night. Hitchcock quickly sent his cameras and actors out to Charing Cross Bridge to film the scene. But when the rushes came back from the developers, the scene at the bridge was nowhere to be found. Hitchcock and his assistants searched through the prints, but could not find it. Finally, Hitchcock discovered that his cameraman had forgotten to put the lens on the camera before filming the night scene.
