He spoke to The Oklahoman newspaper ahead of his movie.

"I play the bully's henchman," he said in 2006. "But everybody got along on the set."

He described his experience on his final movie before leaving movies as a fun one.

"There were rows of bicycles, and they let me have first pick," Garrett said. "There was one scene where we were riding on a gravel road and got to slide to a stop. The guys who could ride worked on that scene. They had a camera on the ground, and in one scene I slid and gravel hit the camera. They really liked that shot, and that's the one they used in the movie."

He had previously worked on local productions such as "Peanuts: A Charlie Brown Tribute" and "Aladdin and His Magical Lamp."
