The Apartment from 1960 a brilliant film directed by Billy Wilder. Starring Jack Lemmon Shirley MacLaine, and Fred MacMurray. This film was released the same year MacMurray was starting his run as the father in the long running show my My Three Sons. So it was odd that he was in this film, playing an evil philandering husband. Their is a bit of a twist here Fred MacMurray replaced the veteran character actor Paul Douglas who died just for for film was to start.
