Where Else You've Seen The Cast Of NCIS

NCIS boasts some seriously impressive longevity — it still draws some impressive ratings and brings in huge guest stars. Much of the appeal comes from its impressive cast, as actors like Mark Harmon, David McCallum, and Pauley Perrette have done a great job of creating rounded, dynamic characters over the years.

As of this writing, there have been just shy of 400 episodes of NCIS, and that isn't counting the show it's spun off from (JAG, which aired 227 episodes) or the two shows that were spun off from NCIS (NCIS: Los Angeles, which is still running and has over 250 episodes, and NCIS: New Orleans, which is still running and has over 130 episodes). That's an awful lot of military criminal investigation!

If you're looking to see some of your favorite actors from NCIS plying their trade in other shows or movies, you've come to the right place. Here are some other places you can see these actors. Full disclosure up front: we're only talking about the main cast from the original NCIS — Scott Bakula is in another castle.

Even though NCIS is recognized as having a truly great ensemble cast, Mark Harmon is really the beating heart that ties the show together. Without his character Gibbs leading the way, much of the charm of NCIS would be gone. However, there are plenty of other places you can catch Harmon if you want to see him in a different role.

Harmon's first screen credit dates back to 1973, and he's made consistent film and television appearances ever since. On the television side of things, Harmon had a major role on the forgotten '80s series Flamingo Road and he appeared in about half of the episodes of St. Elsewhere (which also featured Howie Mandel and Denzel Washington), as well as a crucial arc in the acclaimed hit Moonlighting. In the 1990s, you could catch him on Reasonable Doubts and Chicago Hope.

On the movie side of things, Harmon's had roles in a few major films like Fear and Loathing in Las Vegas and Natural Born Killers. He also starred with Jamie Lee Curtis and Lindsay Lohan in 2003's Freaky Friday.

Besides Mark Harmon, only one actor has appeared in every single episode of NCIS. That actor is David McCallum, who plays Donald "Ducky" Mallard, the team's medical examiner. McCallum was born in 1933 and landed his first credited role when he was 20, so he's been in the game a long time. He is mostly known as a television actor, but he has appeared in a few major films as well.

McCallum has appeared on several television shows, but his biggest starring television role was Illya Kuryakin on The Man From U.N.C.L.E. If you can picture the main duo from the show, Illya is the blonde one. McCallum earned a Golden Globe nomination for the role, later going on to appear on the '80s sci-fi series Sapphire & Steel. If you can picture the main duo from that show, McCallum played "Steel" opposite Joanna Lumley as "Sapphire."

McCallum also appeared in many films, but the one he's best known for is probably The Great Escape. He played Ashley-Pitt, who comes up with the way to get rid of the soil from the tunnels without the guards noticing.

Sean Murray, who plays McGee on NCIS, doesn't actually have a ton of credits to his name — unless you count the fact that he's appeared in 382 episodes of the series. Only Mark Harmon and David McCallum, who have appeared in every single episode, have been in more. He mostly worked as a child actor before hitting the big time on NCIS, but there are probably a few things you've seen him in.

In the early 1990s, Murray had a few major roles to his credit, including playing a central character on the television series Harts of the West, which lasted for a season. He also appeared in This Boy's Life. However, what most people will recognize Murray from is Hocus Pocus, in which he played Thackery Binx.

Interestingly, he was not the voice of Thackery, who spends most of the movie transformed from a person into a cat. Binx is actually voiced by James Marsden, but whenever you see the human version of Thackery, that's Sean Murray.

Pauley Perrette's NCIS character, Abby Scuito, is one of the most recognizable characters on the show. Her jet black hair, complete with bangs and pigtails, and general goth style help her stand out on the team. She's an NCIS forensic scientist, so she also gets to frequently spit out the show's technical jargon when a new mystery pops up.

Outside of NCIS, Perrette doesn't have many major roles to her name. She's done quite a bit of voice work as characters like Lois Lane in Superman vs. The Elite, The Crimson Witch in Scooby-Doo! And Kiss: Rock and Roll Mystery, and Nickleby in Fantasy Hospital. She's also had runs on a few different television shows, like Time of Your Life and Murder One.

Perrette has had small roles in several bigger shows and films, so if you keep your eyes open you'll spot her. She's in Almost Famous, The Ring (2002), Dawson's Creek, 24, and The Drew Carey Show.

Michael Weatherly's character on NCIS, Anthony DiNozzo, serves as frequent comedic relief on a show that regularly focuses on dramatic storylines and serious crimes. His character left the series in 2013 after learning he had a daughter and deciding he needed to be there for her. In reality, Weatherly seemingly left because he was given the chance to headline his own show.

After leaving NCIS, it wasn't long before Weatherly showed back up on television as the title character in Bull. The actor's quick wit and charisma are on full display as trial consultant and psychology expert Jason Bull. As of this writing, Bull is currently in its fourth season.

Outside of those two shows, Weatherly hasn't had many major roles in big television or film projects. He starred in the two-season run of Dark Angel, and made small appearances on shows like The Cosby Show, Charmed, Star Trek: Deep Space Nine, and Ally McBeal.

Brian Dietzen plays Dr. James Palmer on NCIS; he recently stepped in to take over for Ducky as the team's chief medical examiner. His easygoing demeanor helps to alleviate some of the tension on the team, especially considering the grim circumstances he's often working under. Dietzen has a natural charisma that easily transitions to his screen roles — he hasn't done a ton of major stuff outside of NCIS, though.

When you look through Dietzen's credits, not many things jump out at you. A few of the things Dietzen has appeared in include the films Nowhere to Hide, Congratulations, Karaoke Man and a short film called One Minute Time Machine. However, his debut film may ring a few bells for you.

He had appeared on television a few times before, but Dietzen's big screen debut came in the film From Justin to Kelly, the movie that starred the winner and runner-up of the first season of American Idol. Clearly, Dietzen has had quite a step up in his career since then.

Rocky Carroll has the look and voice that guarantee he'll be landing acting roles for years. Luckily, he's got the skills to back it up, too. He plays Leon Vance, the director of the NCIS, and he fits perfectly into the role as the overseeing leader of the team. Carroll also has quite a few other performances you might have seen.

Carroll has done quite a bit of voice work. You can hear him in a few different films as Silas Stone in various DC Comics adaptations, and he voiced Talon on Gargoyles. He's popped up in a few other video games and animated series as well.

The biggest film Carroll has appeared in is probably 1995's Crimson Tide. He's shown up in a few other big movies, too. You can catch him in Yes Man, The Immortal Life of Henrietta Lacks, and The Ladies Man. If it's television you want, Carroll has a few other large parts outside of NCIS, including recurring roles on Chicago Hope, The Agency, and Welcome to New York.

Cote de Pablo is another one of those actors who seems to have all her time taken up by NCIS. She has very few credits to her name outside the show, on which she plays Ziva David, but there are a few places you may have spotted her if you kept your eyes peeled.

She had a small role in it, but the biggest film you can catch de Pablo in is The 33. She plays Katty, who is married to Antonio Banderas' character. She had a bigger role in the western The Last Rites of Ransom Pride, appearing alongside a cast rounded out by Dwight Yoakam, Lizzy Kaplan, Jason Priestley, and Peter Dinklage.

De Pablo has a few small television roles to her name as well, and she also had a starring turn in 2004's The Jury, where she appeared as Marguerite Cisneros in all ten episodes. It seems likely we'll see more from her in the future.

Ellie Bishop is a newer regular to NCIS — Emily Wickersham joined the series in 2013. Since then, she has appeared in over 150 episodes of the series, which hasn't given her much time for other roles. There are a few other things you can catch Wickersham in, however — both on television and in film.

On the television front, she has had a few small roles and a few one-shot guest appearances, several of which have been on big shows. She played Kate for a few episode run on The Bridge, and had guest appearances on shows like Bored to Death and Law & Order: Criminal Intent. She also had a four-episode spot on The Sopranos, where she played Rhiannon.

Wickersham has had a few film roles you can catch her in as well. She had a supporting role as Molly alongside Amanda Seyfried in Gone, and she played Nicole in a supporting role in I am Number Four.

Wilmer Valderrama is the newest series regular on this list — he joined the cast of NCIS as Nick Torres in 2016. Valderrama has been a television mainstay for years, and is one of the few regulars who is better known for a role outside of NCIS. If someone asked who Mark Harmon was, you'd tell them he's the guy from NCIS; If someone asked you who Wilmer Valderrama was, you would tell them that he's Fez.

Yes, Valderrama's debut role propelled him to stardom, as he played foreign exchange student Fez on That '70s Show. His role on NCIS is quite the swerve from his goofy Fez persona, but Valderrama has actually made a point of taking roles that differ from Fez, probably to avoid being typecast.

Valderrama has had several high-profile television roles since That '70s Show wrapped. He popped up on The Ranch for a few episodes alongside his old castmates, and had short runs on Grey's Anatomy and Raising Hope. Some of Valderrama's larger roles have been on shows like Awake and From Dusk Till Dawn: The Series, and he's done some animated voicework. You can hear him in movies like Onward, and he's the voice of the main character in Disney's Handy Manny series.
