Wat's Pig (1997)

In a Medieval castle, a marauder tries to kidnap the twin infant sons of the lord. He makes off with only one, whom he drops about a mile away. A pig rescues this baby, so one brother grows up high on the hog, the other down with the swine; one is lazy, his lost brother is industrious. Years later, when a neighboring prince declares war, the brother in the castle is too soft to fight. Through happenstance, the twins are united just before the final battle. Will the upper-class brother let his humble sibling lead the troops to certain defeat and death?
