The Bat (1959) is a mystery film directed by Crane Wilbur, and co-starring Vincent Price and Agnes Moorehead. Its tagline was "When it flies, someone dies!" The film was based on the 1920 Broadway play by Avery Hopwood and Mary Roberts Rinehart, which was previously filmed as The Bat (1926) and as The Bat Whispers (1930), both directed by Roland West. The 1959 version also features Darla Hood of The Little Rascals in her final film appearance.

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 be a lost film for many years.

For many years this was regarded as a "lost film" with no known prints or elements existing.

This film was highly regarded for its visuals, especially for its cinematography, elaborate sets and special effects. Roland West could only top it by remaking it four years later as Bat Whispers, The (1930) with sound and in an early 70mm process.

Filming took place almost entirely at night.

Mystery writer Cornelia Van Gorder has rented a country house called "The Oaks", which not long ago had been the scene of some murders committed by a strange and violent criminal known as "The Bat". Meanwhile, the house's owner, bank president John Fleming, has recently embezzled one million dollars in securities, and has hidden the proceeds in the house, but he is killed before he can retrieve the money. Thus the lonely country house soon becomes the site of many mysterious and dangerous activities. Written by Snow Leopard
