The Bat (1926) is a silent film based on the 1920 hit Broadway play by Mary Roberts Rinehart and Avery Hopwood, directed by Roland West and starring Jack Pickford and Louise Fazenda. The story takes place in an old mansion, where people look for hidden loot while a caped killer (nicknamed "The Bat") murders them one by one. The film was rediscovered after being thought to have been a lost film for many years.
Comic-book creator Bob Kane said in his autobiography that the villain of the 1930 film was an inspiration for his character Batman.
