The series was originally presented by [[Stewart MacPherson (broadcaster)|Stewart MacPherson]]. The panel comprised [[Richard Dimbleby]], [[Jack Train]], [[Anona Winn]] and [[Joy Adamson]], in later years comedian [[Peter Glaze]] also. A later presenter, [[Gilbert Harding]], was ousted in 1960 by producer [[Ian Messiter]] when, after having drunk a triple gin-and-tonic he had originally offered to Messiter, proceeded to completely ruin the night's game &ndash; he insulted two panelists, failed to recognise a correct identification after seven questions (after revealing the answer upon the 20th question, he yelled at the panel and audience), and ended the show three minutes early by saying "I'm fed up with this idiotic game ... I'm going home".<ref>[http://www.ukgameshows.com/ukgs/Twenty_Questions UK Game Shows: "20 Questions"]</ref> He was replaced by [[Kenneth Horne]] until 1967, followed by [[David Franklin (broadcaster)|David Franklin]] from 1970 to 1972.

In the movie ''[[The 20 Questions Murder Mystery]]'' (1950) then members of the team, including Richard Dimbleby and Norman Hackforth, appear. Together with two newspaper reporters, they work to find the identity of a serial killer who sends in questions for the panel that prefigure his next victim.
