The 180 degree rule in film establishes an axis around which the camera must not cross when filming a scene to avoid showing characters on the same side from opposite angles, which could confuse viewers. The rule sets a single axis so that a character shown on the left side of the frame remains on the left as the camera moves, maintaining spatial relationships for realism and clarity. Breaking the rule involves changing the established axis, risking disorienting effects.
