The Prince and the Pauper

In Tudor England, Tom Canty (Mark Lester) is a poor boy who happens to look exactly like Edward, Prince of Wales, the son of Henry VIII (Charlton Heston). The two meet and trade clothes as a joke on the court. Richard Fleischer sends them out into each other's lives, Tom among the courtiers and Edward beside Miles Hendon (Oliver Reed), while Tom's father, John Canty (Ernest Borgnine), keeps looking for his son.
