Series creator Buddy Ruskin, a former Los Angeles police officer, used his experiences with a special L.A.P.D. youth squad as the basis for this show.
When the series premiered, Williams was 29, Cole was 23, and Lipton was 22.
At the end of every episode, the camera pulls back as the Mod Squad walks off in one direction.
With the death of Clarence Williams III in 2021, Michael Cole is the last surviving cast member.
The "Woody", a 1950 Mercury wood paneled station wagon, was wrecked in The Death of Wild Bill Hannachek (1969). At the end of the episode, the Squad watches their "old buddy" burn, and Linc utters the classic line, "Good bye, old paint". In the reunion movie, "The Return of Mod Squad (1979)," Pete is rich, so he buys a woody when the three of them unite for the task of finding the bad guy.
