While I'm sure lots of movies were filmed in this neighborhood, Haight Ashbury is more famously known as the neighborhood where the hippie movement began and the psychedelic rock music revolution started in the mid to late 60s.
From wiki: In 1967, the neighborhood's fame reached its peak as it became the haven for a number of the top psychedelic rock performers and groups of the time. Acts like Jefferson Airplane, the Grateful Dead and Janis Joplin all lived a short distance from the intersection.
