For his work as Lt. Stone, Malden was nominated for a Primetime Emmy Award for Outstanding Lead Actor in a Drama Series four times between 1974 and 1977, but never won. After two episodes in the fifth season, Douglas left the show to act in movies; Douglas had also produced the film "One Flew Over the Cuckoo's Nest" in 1975. Lt. Stone's new partner was Inspector Dan Robbins, played by Richard Hatch. The show took a ratings nosedive after being rescheduled against another Quinn Martin series on CBS, "Barnaby Jones", and ABC cancelled the series after five seasons and 120 episodes.
