Addison Byron Owen Randall (May 12, 1906 in San Fernando, California – July 16, 1945 in Canoga Park, California) was an American film actor, chiefly in Westerns. He often used a pseudonym for his film work, chiefly "Jack Randall", though he also played roles as "Allen Byron" and "Byron Vance".
Randall began his career as a supporting actor and foil at RKO, but he left when Monogram Pictures promised him the chance to star in films. They were true to their word, and he appeared in a series of Western films through the 1930s and 1940s. Many of Randall's early B-movies with Monogram feature him as a singing cowboy, but his later roles were generally straight Western stories, and all were hampered by the low budgets typical of that studio. Randall adopted his new "Allen Byron" identity in the 1940s in an effort to boost his fading professional fortunes, but the roles he received with new studio Producers Releasing Corporation were not up to the task. He died unexpectedly in 1945 while filming a serial called The Royal Mounted Rides Again for Universal Studios, after a fall from a horse. Some sources attribute his death to injuries sustained during the fall, which in those versions resulted from an attempt to recover a hat he had dropped, while others state that he suffered a fatal heart attack before falling.
