The Prince and the Pauper is a 1937 film based on the book by Mark Twain. This version stars Errol Flynn, Claude Rains and Alan Hale, Sr.. The Husband has been wanting this for many years and received the DVD today as a Father's Day present. We didn't give him a tie. This DVD is a bare-bones disc without much of anything in the way of special features.
