A poor commoner and a young prince each find out how the other half lives in this adventure story based on the classic tale by Mark Twain. Tom Canty (Mark Lester) is a young man from a laboring family who bears a striking resemblance to Prince Edward (also played by Lester), the son of King Henry VIII (Charlton Heston) and heir to his throne. Tom and Edward meet by chance, and they decide to exchange places briefly as a lark; Edward will get to live as an ordinary boy, and Tom will be able to enjoy the perks of royalty. But the two are separated before they can let everyone in on the joke, and Tom discovers as he pretends to be Price Edward that the castle is awash in corruption. Originally released as Crossed Swords, The Prince and the Pauper also features Oliver Reed, Raquel Welch, George C. Scott, and Rex Harrison.
