Fair Warning is a 1931 American pre-Code Western film directed by Alfred L. Werker and starring George O'Brien, Louise Huntington and Mitchell Harris. It is a remake of the 1920 silent film The Untamed. The 1937 film Fair Warning is not a remake of this one. The film's premise came from a novel by Max Brand, which initially was published in serial form in The All-Story from December 7, 1918, through January 11, 1919.
When Whistlin' Dan Barry is warned to leave a town, he refuses to do so. As a result, he defeats Jim Silent (the town's villain) and gets romantic with Kate Cumberland.
A review in Harrison's Reports called Fair Warning "an excellent outdoor picture" that had O'Brien in a fearless role, helping him to win "the spectator's good will, which follows him throughout the story."
