Cast changes were constant early on, as the show tried to find the right ensemble combination. Jeffrey Tambor was the original Franklin Hart (Dabney Coleman's character from the film) during the spring 1982 run, but that fall Peter Bonerz replaced him in that role. He would remain throughout the rest of "9 to 5"'s ABC run. In another key element straight from the movie, resident flunky to Mr. Hart, office snoop Roz Keith (portrayed in the original film by Elizabeth Wilson), was played by British actress Jean Marsh (of "Upstairs, Downstairs" fame). Roz was responsible for digging up the personal dirt on the secretaries and to help Hart scheme his way to the very top.
