 SPOILER: The fight on the cliff between Macaulay Culkin and Elijah  Wood at the end of the film was filmed on a cliff called Palisade  Head in Silver Bay, Minnesota overlooking Lake Superior. In the  story, it was supposed to be The Atlantic Ocean but a suitable rock  face overlook could not be found, and after numerous weekend scouts  all over the country, Silver Bay, Minnesota was chosen. For the  angles looking down at the water, numerous power boats were used to  churn up the water right before cameras were rolled to simulate the  ocean waves. The cliff was 180 feet above the water, but the top ten  feet of the cliff was manufactured. It was created on top of the  actual cliff out of wood and plaster and coated with a rubber  material so that the actors could roll around on it and fight as  needed. The stunt riggers were hidden inside the fake cliff,  controlling safety cables connected to the actors when they were  hanging off the side of the cliff and then Macaulays character is  dropped.
