Alec Baldwin is a guest star as Dr. Thorn (the marine biologist). The episode's story was one of the ideas for the story of "The Simpsons Movie". Al Jean wanted the movie to be about the Simpson family saving manatees. The idea was made into this episode instead. About 11.1 milion people watched the episode when it was first broadcast. The episode shows the Denver Broncos winning the Super Bowl over the Seattle Seahawks. The teams later played at Super Bowl XLVIII, but the Seahawks won the real game.
