The Drums of Jeopardy is a 1931 American pre-Code horror film directed by George B. Seitz and starring Warner Oland, June Collyer and Lloyd Hughes.

The name of the villain in the novel was originally called Boris Karlov, but when the actor Boris Karloff rose to prominence circa 1923, the character's name was changed to Gregor Karlov in the 1923 silent film adaptation to avoid confusion.

In the Russian Empire, the nobleman Prince Gregor Petroff seduces chemist Boris Karlov's daughter Anya, who then commits suicide after becoming pregnant.

After discovering Anya's body with the Drums of Jeopardy, a necklace owned by the Petroff family, Karlov vows revenge against them.
