You remember the theme song. That patriotic, brass-heavy anthem that practically demanded you stand at attention in your living room. For ten years, JAG—short for Judge Advocate General—was the backbone of Tuesday night television. It was Top Gun meets Law & Order, a show that took the rigid world of military law and turned it into high-stakes drama.
But then the screen went dark after that famous coin toss in 2005.
Since then, the JAG TV show cast has taken some wild turns. Some stayed in the spotlight, becoming the faces of massive franchises, while others pivoted into directing or left Hollywood behind entirely. If you’ve ever wondered why the "will-they-won't-they" chemistry of Harm and Mac felt so real, or where the rest of the crew ended up after their tours of duty, you aren't alone.
David James Elliott (Harmon Rabb Jr.)
The man was the face of the show. David James Elliott played Harmon "Harm" Rabb Jr., the ace pilot turned lawyer who seemed to survive more plane crashes than most people do commutes. Honestly, it’s hard to imagine anyone else in those dress whites.
When JAG ended, Elliott didn't just vanish. He jumped straight into another legal drama called Close to Home, but it didn't quite capture that same magic. He’s worked steadily for two decades, appearing in everything from CSI: NY to playing John Wayne in the movie Trumbo.

In a weirdly poetic twist, he’s actually married to Nanci Chambers in real life. You might remember her as the ambitious (and often hated) Lieutenant Loren Singer on the show. Talk about a plot twist—Harm married the woman who was essentially his office nemesis. Most recently, he popped back up as Harm in NCIS: Los Angeles, looking like he hadn't aged a day, though the news about his character's relationship with Mac was... complicated.
Catherine Bell (Sarah "Mac" MacKenzie)
Catherine Bell joined the show in season two after the original partner, Meg Austin, was written out. It was the best move the producers ever made. As Marine Major Sarah "Mac" MacKenzie, Bell brought a toughness that balanced out Harm’s cowboy energy.
After the series finale, Bell became the queen of cable TV. She spent seven seasons on Army Wives and then transitioned into the massive Hallmark franchise The Good Witch. She’s basically been on television consistently since 1996.
She also made that highly-anticipated return to the NCIS universe a few years back. For fans who were dying to know the result of the coin flip from the finale, the reunion was bittersweet. We found out they did get engaged, but they also broke up because their careers kept them on opposite sides of the globe. Kinda heartbreaking, right?

The Bud and Harriet Connection
If Harm and Mac were the "cool" couple, Bud Roberts and Harriet Sims were the heart of the JAG office. Patrick Labyorteaux (Bud) and Karri Turner (Harriet) played their roles with a sincerity that felt grounded.
- Patrick Labyorteaux: He’s actually one of the only actors to bridge the gap between JAG and NCIS multiple times. He’s appeared as Bud Roberts on the original NCIS as a Captain, showing that the character actually had a successful career progression.
- Karri Turner: She didn't stick with acting as heavily as her co-stars. After the show, she focused a lot on USO tours, traveling the world to support real-life military personnel. It’s a cool case of life imitating art.
The Admiral: John M. Jackson
You couldn't have JAG without Rear Admiral A.J. Chegwidden. John M. Jackson played the ultimate "tough but fair" boss. He was a former SEAL, a brilliant lawyer, and the guy you definitely didn't want to disappoint.
Jackson is another cast member who refused to let the character die. He brought the Admiral over to NCIS and NCIS: Los Angeles as a recurring mentor figure. Outside of the uniform, he’s had a great run in shows like Bones and Grey's Anatomy. Honestly, the man just radiates "authority figure" energy.
What Most People Get Wrong About the Show
A lot of people think JAG was just a military propaganda tool or a boring courtroom procedural. That’s a mistake. The show was actually incredibly progressive for its time, tackling things like sexual harassment in the ranks, the ethics of drone warfare (way before it was a mainstream topic), and the struggle of veterans returning to civilian life.

It was also a "zombie" show. NBC actually cancelled it after the first season! CBS picked it up as a mid-season replacement, and it went on to run for nine more years and spawn a franchise—NCIS—that is still on the air today. Without the JAG TV show cast proving there was an audience for military procedurals, we’d never have Gibbs, DiNozzo, or the dozen spin-offs that followed.
Tragedies and Transitions
It hasn't all been red carpets and reunions. Trevor Goddard, who played the Australian rival Mic Brumby, passed away in 2003 before the show even finished its run. It was a shock to the cast and fans alike.
Then there's the supporting players who went on to massive things. Did you know Terry O'Quinn (John Locke from Lost) was a recurring Admiral on JAG? Or that Steven Culp, the CIA agent Clayton Webb, was juggling roles on three different hit shows at once? The depth of talent in the guest cast was honestly staggering.
Why We’re Still Talking About Them in 2026
The show has a legacy because it felt authentic. Creator Donald P. Bellisario was a Marine himself, and he insisted on a level of detail that other shows lacked. When you see the JAG TV show cast now, there’s still a huge amount of respect for the work they did.
If you're looking to dive back into the world of Harmon Rabb and Sarah MacKenzie, here is the best way to do it:
- Watch the "Ice Queen" and "Meltdown" episodes: These are the Season 8 episodes that served as the backdoor pilot for NCIS. It’s fascinating to see Mark Harmon’s Gibbs interact with the JAG crew.
- Check out the NCIS: Los Angeles crossover: Specifically, the Season 10 finale and Season 11 premiere. It’s the closest thing to a "reunion movie" we’re likely to get.
- Stream the original pilot: It has a completely different feel and features Tracey Needham as Harm's original partner. It’s a great "what if" look at the show’s history.
The uniforms might be in storage, but the impact of this cast on modern TV is still very much active duty.
