The Lord of the Rings
Eric Saindon, the visual effects supervisor in The Lord of the Rings, struggled to create Gollum, seeing as the motion-capture suit was not yet a common technology in 2001. "When we did Gollum, no one had really done a CG creature mixed with live-action that you were supposed to believe was just a creature in the scene," he said. Saindon's VFX team invented the technology that brought Gollum to life, and they won an Oscar for the monumental feat.
