Basil Rathbone's real-life son, John Rodion, has his head chopped off early on in this historical melodrama often mistakenly referred to as a horror film. Yes, a second-billed Boris Karloff does stomp about on a club-foot as the Duke of Glouchester's chief executioner, Mord, but Karloff's presence is really more colorful than horrifying. Rathbone is the main villain here, as the Duke of Glouchester, the deformed second brother of Edward IV (Ian Hunter), whose throne he covets. But before he can place himself on that exalted chair, there are quite a few relatives and pretenders to be rid off.
