The song at the beginning set the tone for the rest of the story. The musical scene where Hank, King Arthur, and Sagramore singing Busy Doing Nothing is a fun scene and the song is catchy. I'm hummed that some for years.

Of course, the screenplay took liberties with the original story Mark Twain wrote. In the story, after the death of King Arthur, Hank tries to make England into a republic and the barons/knights revolt against him. In a battle, sets up a wire fence and attaches a dynamo to it electrocuting many knights.

Twain's novel is a good read and the movie is fun entertainment.
