A friend and colleague of Harm’s father, Admiral Thomas Boone, often helped save him from the court-martial. Boone led a distinguished career and rose to the rank of Rear Admiral, but never received another promotion due to allegations of war crimes he committed in Vietnam.
Terry O’Quinn began acting in the 1970s and eventually went on to direct movies as well. He’s most known for his role as John Locke on the TV series Lost. He has since appeared in various shows including Emergence, The Blacklist and as a lead actor in the show “Secrets and Lies”.
Richard McGonagle
You might remember Captain Richard Carey who appeared briefly in Season 6 as part of the judiciary. He’s played by Richard McGonagle, who’s best known for his voice-over work in video games, movies and television shows.
You can watch Richard in various shows such as The X-Files, The West Wing, and The Twilight Zone, or listen to his awesome voice in famous video-games such as Metal Gear Solid 3: Snake Eater. Whether in voice over roles or on film, he always gives an excellent performance.
Glenn Morshower
You may not remember Chief Petty Officer Ned Bannon, who was assigned to work the U.S.S. Seahawk alongside the JAG crew. However, despite his seemingly uneventful time on the show, Glenn went on to play many more TV and film roles.
Glenn seems to have a penchant towards playing the role of a military officer. Perhaps he was inspired by his time on JAG. That worked out pretty well though because he actually does a very good job at it. You may have seen him recently as Marshal Winthrop on The Resident.
Andrea Thompson
The seductive and powerful Captain Alison Krennick was Harm's direct superior in Season 1 of JAG. She made extremely overt sexual advances towards Harm, even straight up telling him she wanted to sleep with him. This is a big no-no in the military, so obviously her shenanigans didn’t last beyond the first season.
After leaving the show, Andrea Thompson went on to play Detective Jill Kirkendall on four seasons of crime drama NYPD Blue, leaving in April 2000 to pursue a career in journalism working for CNN. Thompson’s last role lasted only 2 episodes in the crime-drama show Bones.
Montel Williams
We were just as surprised as you to realize that Montel Williams played Lt. Curtis Rivers on JAG, I mean, the former U.S. Marine Corps and Navy soldier is now one of the more recognizable faces and voices in Hollywood. Yet, He too started out as just a side character.
With nearly 50 years of acting experience under his belt, Williams has since, acted in numerous shows and movies, produced, and even hosted his own show. You may have also seen his recently on The Resident as HIMSELF! Pretty cool, huh? He’s also an outspoken advocate for US military veterans.
