A retrospective of the classic game show, What's My Line, in which a four-member celebrity panel attempted to identify a contestant's occupation through yes or no questions. In addition, each episode featured a celebrity mystery guest that the panelists tried to identify the guest while blindfolded. The show ran from 1950-1967 and prominently featured John Daly, Bennett Cerf, Arlene Francis, and Dorothy Kilgallen. This documentary looked back on the show 25 years after it premiered.
Unfortunately the movie What's My Line At 25 is not yet available on HBO Max.
