(Photo: YouTube | The Streets of San Francisco 1972) Baby boomers and seniors will remember watching veteran actor Karl Malden play Lieutenant Michael Stone from 1972-1977 on The Streets of San Francisco. For most of that time his co-star was Michael Douglas, playing a young inexperienced plainclothes detective, Steve Keller. Michael Douglas' acting and producing career was on the rise while the series was on the air, and he left the show after One Flew Over the Cuckoo's Nest, which he had produced, won the Academy Aware for Best Film (1975). His character Steve Keller left the show to teach at college, while Douglas went on to produce and star in many more movies including winning another Academy Award, this time as Best Actor, for 1987's Wall Street. Karl Malden was 60 years old when The Streets of San Francisco started in 1972, with 45 movies already under his belt - including 1951's A Streetcar Named Desire, for which he won an Academy Award as Best Support Actor.

As a senior actor, he went on to star in 2 television mini-series and 15 more movies, ending with his last film in 2003 when he was 90 years old - Broadway: The Golden Age, by the Legends Who Were There. Years later, 92-year-old senior citizen Karl Malden accepted an Award from the Eugene O'Neill Theater Center in 2004, from former co-star Michael Douglas and actor Kirk Douglas (Michael's father and Karl's friend). That same year, Karl Malden and his wife Mona were present at a tribute to his former Streets of San Francisco co-star Michael Douglas (below). (Mona and Karl Malden Photo: YouTube | Golden Globe Awards 2004) Michael Douglas and Karl Malden apparently developed a personal and professional relationship that mirrored their partner's relationship on the show, with veteran Malden regarding Douglas as a son and Douglas referring to Malden as his mentor. The third star of the show was the city of San Francisco, as the series was filmed entirely on location there. In 1992 a TV reunion movie Back to the Streets of San Francisco was aired; although Karl Malden played his original character Mike Stone in the movie, Michael Douglas did not appear. A1. Both David Soul and Paul-Michael Glaser made several appearances on The Streets of San Francisco before starring in Starsky and Hutch as police officers. A2. Richard Hatch had appeared on Broadway in the 60's and in the early 70's starred on the daytime soap All My Children as Philip Brent, before landing the role of Inspector Dan Robbins in 1976.
