Before Nick Nolte picks up Eddie Murphy, Nolte is driving in his car huge white car down a random hill in San Francisco. If you look at the middle right of the screen, you will see what is later Eddie Murphy's super dusty, brown Porsche driving a few cars in front of Nolte's car. The same scene is used later when Nolte and Murphy are following "Luther" in Murphy's Porsche fresh out of the parking garage and the first time we are supposee to see Murphy's car.
