The scene where Arthur drives his "racing car" around a track was shot at the now defunct Danbury Fair Racearena in Connecticut. The type of car that Arthur drove was never raced there, it was primarily for Modified stock cars and was one of America's great short tracks. Sadly, despite its great success, the land became too valuable and it gave way to a shopping mall. The Danbury Fair Racearena closed on October 12, 1981, shortly after the movie was filmed.
