Mark Twain's classic tale gets a bit of a modern-day makeover in this animated adventure that originally aired on television in the 1970s, the story of a factory worker from 20th-century Connecticut who's sent back in time to the days of King Arthur. While adjusting to his new surroundings, the accidental time traveler earns the admiration of the locals. But he also angers Merlin the Magician, who sees him as a threat.
