Les rues de San Francisco

By all accounts Karl Malden and Michael Douglas developed a strong professional and personal relationship from their time on the series. Twenty years after last working together on an episode they were both onstage at the 1996 People's Choice Awards. Malden referred to Douglas as "the son I never had" and mentioned that he had wanted producer Quinn Martin to cast Douglas on the series. Douglas responded to the compliment by calling Malden "my mentor," and both also expressed that they enjoyed working together on the show.

End credits (from seasons 2-5): Photographed Completely On Location in San Francisco. In season 1, the production was split with exteriors filmed in San Francisco and interior scenes filmed at the Burbank Studios in Burbank, California.
