The film was shot over eleven weeks during the autumn of 1979; Hurricane David in early September delayed production. Golf scenes were filmed at the Rolling Hills Golf Club (now the Grande Oaks Golf Club) in Davie, Florida. According to Ramis, Rolling Hills was chosen because the course did not have any palm trees. He wanted the film to feel that it was in the Midwest, not Florida. The explosions that take place during the climax of the film were reported at the nearby Fort Lauderdale airport by an incoming pilot, who suspected that a plane had crashed. The Fourth of July dinner and dancing scene was filmed at the Boca Raton Hotel and Club in Boca Raton, Florida, while the yacht club scene was shot at the Rusty Pelican Restaurant in Key Biscayne, Florida.
