Guest star Shirley Booth had headlined the iconic sitcom Hazel (1961) and was to star in the shortlived sitcom A Touch of Grace (1973). However this episode of ''The Ghost & Mrs. Muir'' marks Booth's only sitcom guest role appearance. Booth's other television guest roles are all in self-contained episode of anthology series such as CBS Playhouse 90.
Madame Tebaldi, the pseudo-Italian name under which Shirley Booth's spiritualist character operates, recalls that of the iconic comic character Madame Arcati, the spiritualist in Noël Coward's ''Blithe Spirit''.
