McMillan & Wife/Season 4

Season five of McMillan & Wife saw a title change to the show. Due to contract disputes, actress Susan Saint James, who played Sally McMillan, left the series. Her character was written out as having died in a plane crash following season five. As such, the name of the show was changed to McMillan with Rock Hudson flying solo as San Francisco police commissioner Stewart "Mac" McMillan. This was the final season of the show and lasted only six episodes, which aired on NBC from September 29th, 1974 to February 16th, 1975.

In addition to the series' mainstay, as well as John Schuck reprising the role of Sergeant Charles Enright, season six of McMillan brought in some fresh faces in the form of Martha Raye as Agatha Thornton, replacing Nancy Walker's Mildred, who had also departed from the show. There was also Richard Gilliland as Sergeant Steve DiMaggio, Gloria Stroock as Maggie and Bill Quinn as police chief Paulson.
