The Caveman's Valentine is a 2001 American mystery-drama film directed by Kasi Lemmons and starring Samuel L. Jackson based on George Dawes Green's 1994 novel of the same name.

A former family man and pianist studying at Juilliard music school, Romulus Ledbetter, now suffers from paranoid schizophrenia and lives in a cave in Inwood Park, New York.

He believes that a man named Cornelius Gould Stuyvesant is controlling the world with rays from the top of the Chrysler Building, and that his mind is inhabited by moth-like seraphs.

Determined to discover the truth behind Scotty’s death and prove his worth to his daughter, Romulus manages to get an invitation through a former friend to perform one of his compositions at Leppenraub’s farm.

The website's critical consensus reads, "The Caveman's Valentine has an intriguing premise, but the film falls flat under the weight of its ambition.
