Roger Guyett joined ILM in 1994 to work on the groundbreaking computer animation in Casper. He was a principal member of the team that produced over 40 minutes of 3D character animation, marking the first time in cinematic history that a leading role was played by an entirely synthetic actor.

Guyett continued to climb the ladder with several big-budget films in the '90s. He led the technical direction of key sequences in Dragonheart, where ILM's proprietary facial animation software brought Draco the CG dragon to life. He was the Computer Graphics Supervisor on Twister, overseeing a team of digital artists that created stunning images of one of nature's fiercest weather events. Three years later, Guyett was recognized with a British Academy Award® for his innovative work as co-visual effects supervisor on Saving Private Ryan.

The recognition continued when Guyett earned Oscar and BAFTA nominations and won the Visual Effects Society Award for Best Visual Effects for his work on Harry Potter and the Prisoner of Azkaban. Guyett also earned Oscar, BAFTA, and VES nominations for his work as the Visual Effects Supervisor and Second Unit Director in both Star Trek and Star Trek Into Darkness.

In 2009, Guyett was named to the "Digital 25: Visionaries, Innovators and Producers List," by the Producer's Guild of America, which honors those who have made the most vibrant and exciting contributions to the advancement of digital entertainment and storytelling. Guyett is a member of both the Academy of Motion Picture Arts and Sciences and the British Academy of Film and Television Arts.
