 All scenes in Kevins car were shot weeks later than the rest of the  film at a park near the directors house (instead of a wooded area  miles away). Those scenes were shot on the side of a street in the  park, rather than the parking lot that was intended. When the actors  and director pulled into the parking lot, they found numerous groups  of men engaged in sexual activity directly in front of their cars.  (None of that action was filmed)
