Speed King on AllMovie

It sounds like an interesting concept -- take star/crack stuntman Richard Talmadge and have him play a motorcycle champion who gets entangled in Graustarkian intrigue. But this picture is not up to par for Talmadge, and he's only good in one-half of the dual role he is given (luckily the double exposures are kept to a minimum). Motorcycle competitor Jimmy Martin (Talmadge) is a dead ringer for Charles, the king of Mandavia (also Talmadge). Traitor Rodolph D'Henri (Harry Van Meter) has kidnapped the king and he tricks Martin into standing in for the missing ruler. Martin goes along with it until he realizes that D'Henri's motives are less than honorable. He reveals his true identity to Princess Margaret of Alvernia (Virginia Warwick), with whom he has fallen in love, and then he turns his efforts towards foiling D'Henri's plot. He rescues the king and exposes D'Henri for the villain he really is.
