Bill Kroyer is an award-winning director of animation and computer graphics commercials, short films, movie titles and theatrical films. He and Jerry Rees were the main animators for the CGI sequences in TRON. He currently works at Rhythm and Hues Studios as their Senior Animation Director.
Kroyer began his animation career in 1975 by working in a small commercial studio. In 1977 he ended up at Disney Studios but left Disney because he didn't want to work on The Black Cauldron. It was then he met future TRON director Steven Lisberger, who was working on Animalympics. After Animalympics was completed, Lisberger developed Tron and sold it to Disney.
After TRON was finished, Kroyer decided to stay with computer animation instead of traditional animation and worked at Robert Abel & Associates and Digital Productions. In 1986, he and his wife, Sue, started Kroyer Films to combine computer animation with hand-drawn animation. They made a short film titled Technological Threat and it was nominated for an Academy Award in 1988.
Soon after he joined Rhythm and Hues Studios as Senior Animation Director and supervised the CGI animation for films such as Garfield, Scooby Doo, Cats & Dogs and The Flintstones in Viva Rock Vegas.
