Performance Capture Pioneer
Recording an actor's body movements and facial expressions and using that data to drive a fully digital character. The human performance survives inside a non-human form.
The Polar Express
Tom Hanks played several roles, recorded as movement and facial data that drove digital characters. The human performance survives in the animation. It was an early large-scale test of the technique.
The Hobbit: The Desolation of Smaug
Benedict Cumberbatch gave Smaug both his voice and his motion capture. The dragon's sneer and the way he turns his head carry a human performance inside a giant digital body. You feel you are being talked down to by something very old and very clever.
