In 1989 Judge began studying at the Howard Fine Studio in LA. A few of his early roles were in the 1990s Bird on a Wire, Cadence, Neon Rider and MacGyver with future Stargate SG-1 star Richard Dean Anderson. In the ensuing years, Judge had small parts in various television shows and movies such as 21 Jump Street (with future SG-1 director Peter DeLuise), The Fresh Prince of Bel-Air, and House Party 2, and as a regular on Sirens from 1994 to 1995. 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 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 sets of actors for each of the principal roles, but eight or ten for the role of Teal'c. Judge was confident he got the part when they dismissed everyone who read for the part except him. Out of all t! he actors in Stargate SG-1, Judge has been in the most episodes. More recent works of Judge's include guest spots on Andromeda and Stargate Atlantis, the television movie Personal Effects, and the films Snow Dogs and A Dog's Breakfast, the latter written and directed by fellow Stargate actor David Hewlett. Judge appeared in "Anonymous", the October 26, 2010 episode of NCIS: Los Angeles.
