Don Quixote (1941)

A man named Alonso Quixano (or Quijano), a retired country gentleman nearing 50 years old, lives in an unnamed section of La Mancha with his niece and a housekeeper. He has become obsessed with books of chivalry, and believes their every word to be true, despite the fact that many of the events in them are clearly impossible. Quixano eventually appears to other people to have lost his mind from little sleep and food, and so much reading. He decides to become a knight-errant, and with his fat, food-loving, squire Sancho Panza, sets out on an hilarious misadventure.
