The Streets of San Francisco is a 1970s television police drama filmed on location in San Francisco, California, USA, and produced by Quinn Martin Productions, with the first season produced in association with Warner Bros. Television (QM produced the show on its own for the remainder of its run), where it starred Karl Malden and Michael Douglas who were both detectives in the Bay Area. The show ran for five seasons, between September 16, 1972 and June 9, 1977 on ABC, amassing a total of 120 60-minute episodes. The series started with a pilot movie of the same title (based on the detective novel Poor, Poor Ophelia by Carolyn Weston) earlier in 1972.
The show revolved around two police officers who investigated homicides in San Francisco. The centre of the series was a veteran cop and widower, Lt Mike Stone (Karl Malden), who had more than twenty years of police experience and was now assigned to the Homicide Detail of SFPD's Bureau of Inspectors (ex: Detective Division). He was partnered with a young, plainclothes detective and energetic partner, Assistant Inspector Steve Keller (Michael Douglas), a college graduate, age twenty-eight, who had no experience in the police force. Stone would become a second father to Keller as he learned the rigors and procedures of detective work. Eventually, Keller was promoted to full inspector. As the series went on, Douglas became a star in his own right. Mike's daughter, Jeannie Stone (Darleen Carr), made occasional appearances.
After the second episode of the fifth and final season, Douglas left the show after successfully producing the film One Flew Over the Cuckoo's Nest, which won the Academy Award for Best Film for 1975. He in turn would also establish a film career. His character's absence was explained by having him take a teaching position at a local college, while Lt. Stone was partnered with another detective, Insp. Dan Robbins, played by Richard Hatch, who had started his career on the ABC soap All My Children and would later go on to Battlestar Galactica. The change was not popular with audiences, and the show ended in 1977, due to low ratings. Also in 1977, writer James J. Sweeney won an Edgar Award from the Mystery Writers of America for his teleplay for the season four episode "Requiem for Murder".
