From 1935 until his retirement in 1943, mustachioed Harry Worth (not to be confused with the British silent era actor of the same name) played the quintessential "Boss Villain" in scores of B-Westerns, a thorn in the sides of everyone from Red Ryder to Hopalong Cassidy. In between these assignments, Worth could be found further down the cast lists in Grade-A productions, as a Hindu in Easy Living or a Caballero in The Mark of Zorro (1940). But he was apparently happiest at modest Republic Pictures, where he played Frank James to Don "Red" Barry's Jesse in Days of Jesse James (1939). (For some reason, the studio billed him Michael Worth in that one.) Oilier even than Harry Woods and more refined than Roy Barcroft, Harry Worth was at his hissable best as John Wilkes Booth in Tennessee Johnson (1942) and as a desperate gunman in the Three Mesqueteers series entry Riders of the Rio Grande (1943), his final credited film performance. Worth spent the remainder of his career in unbilled bits.
