 The scene near the end of the movie where the blue car is driven  onto the boat was filmed at Cape Florida State Park on Key Biscayne.  A new fishing pier was built by the movie crew to provide the ramp  and a car was prepared with the engine and all fuel and brake lines  removed and the vehicle steam cleaned so no oil or gas would pollute  Biscayne Bay. The plan was to film the shot several times but the  first one went so well that the additional takes were cancelled.
