Dimensions of Dialogue (, lit.: Possibilities of Dialogue) is a 1983 Czechoslovak animated short film directed by Jan à  vankmajer. It is 12 minutes long and created with stop motion.
The animation is divided into three sections. Objective Dialogue (Dialog vÃÂcný) shows Arcimboldo-like heads gradually reducing each other to bland copies; Passionate Dialogue (Dialog vÃ¡à ¡nivý) shows a clay man and woman who dissolve into one another sexually, then quarrel and reduce themselves to a frenzied, boiling pulp; and Exhaustive Dialogue (Dialog vyÃÂerpávajÃÂcÃÂ) consists of two elderly clay heads who extrude various objects on their tongues (toothbrush and toothpaste; shoe and shoelaces, etc.) and intertwine them in various combinations.
Terry Gilliam selected the film as one of the ten best animated films of all time.
