The Man Who Wouldn't Talk is a 1940 mystery film directed by David Burton and starring Lloyd Nolan, Jean Rogers, and Richard Clarke. It is a remake of the 1929 film The Valiant which had starred Paul Muni, and was based on a play of the same name. It was Nolan's first film for Twentieth Century Fox, where he went on to be a successful star of B Movie mysteries such as the Michael Shayne series. Nolan's portrayal of the lead character was deliberately more subdued than Muni's had been, and the film was "opened up" with the addition of flashback scenes and other devices to make it less dialogue-based than the original.
