Alias Jimmy Valentine is a 1928 American sound part-talkie crime drama film directed by Jack Conway and starring William Haines, Leila Hyams, Lionel Barrymore, and Karl Dane. The film features talking sequences along with a synchronized musical score with sound effects using both the sound-on-disc and sound-on-film process. The film is based on the 1903 O. Henry story "A Retrieved Reformation", which was turned into the 1910 play Alias Jimmy Valentine by Paul Armstrong. The play toured in travelling production companies making it extremely popular. It was revived on Broadway in 1921. Two previous film adaptations had been produced at the old Metro Studios. A 1915 film version was directed by Maurice Tourneur and a 1920 version starring Bert Lytell was directed by Edmund Mortimer and Arthur Ripley.

Leila Hyams was an American actress who came from a show business family. Her relatively short film career began in 1924 during the era of silent films and ended in 1936. The blonde blue-eyed ingenue and leading lady appeared in more than 50 film roles and remained a press favourite, with numerous magazine covers.
