Stanley Kubrick is considered an auteur director due to his consistent artistic vision and themes across his films. As a director, Kubrick took on many roles such as cinematographer, editor, and soundman on his early films to maintain full control over his artistic vision. His films featured recurring themes of fear, desire, and violence that became hallmarks of his style. Kubrick's magnum opus 2001: A Space Odyssey exemplified his meticulous approach and cemented his status as an auteur through its innovative special effects and exploration of philosophical themes.
