 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 Americas 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.
