The League of Frightened Men is a 1937 American mystery film based on the 1935 novel of the same name, the second Nero Wolfe novel by Rex Stout.

Hibbard shares with Wolfe that his daughter (Irene Hervey) is romantically involved with Chapin's elder brother, Mark (Joseph Allen).

They manage to break free and Inspector Cramer (Edward McNamara) promptly arrests Mark for kidnapping.

Instead, the actual murderer of the men is found to be one of Hibbard's friends, banker Ferdinand Bowen (Walter Kingsford).

The novel The League of Frightened Men by Rex Stout was adapted into the film by script writers Eugene Solow and Guy Endore.
