Kinoautomat was the world's first interactive movie, conceived by Radúz Činčera for the Czechoslovak Pavilion at Expo '67 in Montreal. At nine points during the film the action stops, and a moderator appears on stage to ask the audience to choose between two scenes; following an audience vote, the chosen scene is played.
