The cast of the military drama, JAG, have a varied and distinguished background including a former rock band member, a computer geek, a child star, a comedian, a school teacher, a documentary producer, a boxer, and more. Donald P. Bellisario has taken this unique group of talented individuals and transformed them into a show which attracts fans from all walks of live. David James Elliott joined the original cast of JAG and is the lead male character, Lt. CMDR Harmon Rabb, Jr. David's goal was to be in a rock band. During high school he became interested in acting and the rest is history. He has recently begun developing his talents as a director. David's beautiful wife, Nanci Chambers, plays the role of Lt. Lauren Singer in the series. Catherine Bell was first spotted on JAG in the episode Skeleton Crew. She portrayed Rabb's girlfriend who is murdered. Bell enjoyed her experience on JAG so much she wrote to Donald Bellisario and suggested she be cast as Rabb's new partner, explaining her being the image of his dead girlfriend would add good plot tension to the show. Mr. Bellisario must have agreed with her because Catherine became the female lead, Sarah "Mac" MacKenzie, when JAG moved to CBS for Season 2. Patrick Labyorteaux is one of the few remaining cast members from the original pilot episode. He along with David James Elliot, have been with the show from the beginning. Patrick's character, LT. Bud Roberts, Jr., is the most human of the cast. Striving to fulfill his dreams, Bud encounters problems with a down to earth, lovable persona. He is the youngest member of the legal team and as such looks up to and seeks guidance from his mentors, arm and Mac. A former Texas school teacher, John M. Jackson is the JAG. As Admiral Chedwiggen, John is the commanding officer of the JAG Corps. He exhibits calm and demands perfection from his staff and directs their activities with a strong, determined will expected of an ex-SEAL. Karri Turner, a comedian with a brilliant wit, plays Lt. Harriet Sims. Lt Sims is married to Bud Roberts and brings to the ensemble a charm and openness of emotion sometimes missing in the other strong characters. Harriet manages to keep everything in the office running smoothly while encouraging her husband to achieve his goal's, raising a son, all while reminding the rest of the staff of their personal and professional commitments. Together with the Gunny, played by Randy Vasquez, and Tiner, Chuck Carrington, the ensemble under the direction of Donald P. Bellisario continues to intrigue and entertain us on weekly basis. JAG is aired on CBS every Tuesday and USA Networks daily. For episode dates, check our calendar.
