|Dirty Harry: the race begins|
Filmed on location, Dirty Harry showcases many San Francisco landmarks, several of which are used in this sequence. The Google map below shows all of Harry's stops as he runs from phone to phone trying to keep pace with Scorpio's game. Click on the map markers to see a movie still of that location. Zoom into "street view" and you'll get to examine some of the surroundings seen in the film — the marina, Forest Hills Station, the hamburger stand at Aquatic Park, and the big cross in Mt. Davidson park where Harry and Scorpio ultimately meet, for better or worse. While an exact street route is never detailed in the film, the lines on the map show the minimum distance between locations, all but one of which Harry travels on foot.
