The filming of Farewell, My Lovely (1975) was a trip down memory lane for Robert Mitchum. The movie brought him back to the derelict neighborhoods he knew decades prior when he was a poverty stricken teenager. One night, as Mitchum handed money to vagrants on the streets, his actions attracted the attention of an old beat cop on patrol. The officer took a good look at Bob and said, "So you're back."
This film spent several days shooting on location at the Harold Lloyd estate. When Mitchum goes to meet Rampling at her place, the two are actually relaxing in Harold Lloyd's opulent office/den. The estate was used in a number of films during that period, including Shampoo (1975) with Warren Beatty, the Schwarzenegger vehicle Commando (1985) and an episode of the TV series Columbo (1971).
The dark pin-striped suit worn by Robert Mitchum in the film was the only one available from the wardrobe department, with no backup suit available if needed. Originally made for Victor Mature during the 1940s, Mitchum hated the outfit, and complained constantly during production about having to wear "Victor Mature's old farted-up suit."
