Judge's largest role came in 1997 with "Stargate SG-1". While at a friend's house, he saw his friend's roommate practicing for an audition for the show and was intrigued. While the roommate was away, Judge looked at the audition notes, then called his agent and insisted he get him an audition, or lose him as a client. At the audition there were three actors trying out for each of the other principal roles, but eight or ten for the role of Teal'c. Judge was confident that he had acquired the part when they dismissed everyone who had read for the part except him.
