Definitely the best adaptation of Mark Twain's novel about King Edward VI of England and his pauper doppelgänger Tom Canty (played here by the Mauch twins) swapping places after a chance encounter at Whitehall Palace and a fancy dress ball. Errol Flynn is great as Miles Hendon leading the "pauper" king on a series of adventures as they attempt to reinstate them both to their rightful places. Claude Rains is suitably devilish as Hertford. Henry Stephenson and Alan Hale - both never far from Flynn - make up rest of the team in this great little adventure yarn.
