Anomalisa is a 2015 American stop motion animated psychological comedy-drama film written and directed by Charlie Kaufman, who co-directed with Duke Johnson. It was based on Kaufman's 2005 audio play of the same name under his alias Francis Fregoli, which is considered an exploration of the Fregoli delusion. Anomalisa follows British middle-aged customer service expert Michael Stone, who perceives everyone as identical except for Lisa Hesselman, whom he meets in a Cincinnati hotel.

Stop motion is an animated filmmaking technique in which objects are physically manipulated in small increments between individually photographed frames so that they will appear to exhibit independent motion or change when the series of frames is played back. Any kind of object can thus be animated, but puppets with movable joints or plasticine figures are most commonly used. Puppets, models or clay figures built around an armature are used in model animation. Stop motion with live actors is often referred to as pixilation. Stop motion of flat materials such as paper, fabrics or photographs is usually called cutout animation.
