You probably know the face. Maybe it was that frantic energy in a crime lab or a quick, weirdly specific joke in a sitcom you binged three years ago. Rob Kerkovich has that "hey, it’s that guy" quality that makes him a staple of modern television.
Most people just call him Sebastian. For seven seasons on NCIS: New Orleans, he played Sebastian Lund, the socially awkward but brilliant forensic scientist who eventually traded his lab coat for a field badge. But if you think that's the only entry on the list of rob kerkovich movies and tv shows, you’re missing the best parts of his career.
Honestly, he’s one of those actors who popped up in almost every major comedy of the 2010s before landing his big break.
The Sebastian Lund Era and the NCIS Impact
Let's be real: NCIS: New Orleans is the elephant in the room. From 2014 to 2021, Kerkovich was the heart of the Jefferson Parish Coroner’s Office.
What made his performance work wasn't just the technical jargon. It was the evolution. Sebastian started as a quirky, somewhat bumbling nerd—a trope we’ve seen a million times. But Kerkovich gave him layers. You watched him deal with the trauma of his first kill in the field, a plot point that many procedurals would have brushed off by the next episode. He didn't just "do kung fu" and become a superhero overnight. He stayed relatable.
He appeared in over 150 episodes. That’s a massive chunk of a career. Even now, in 2026, fans still find him through Paramount+ marathons, proving that the "Lund-thusiasts" are still a very real thing.

The "Wait, Was He in That?" Years
Before he was solving murders in the Big Easy, Kerkovich was basically a journeyman of the sitcom world. If you blink, you’ll miss him, but his credits read like a "Best Of" list for TV junkies.
- Parks and Recreation: Remember the "Cones of Dunshire" episode? He played Dirk.
- New Girl: He showed up as Tim in the episode "Fired Up."
- Brooklyn Nine-Nine: He was in the pilot! He played a character named Blunder.
- Modern Family: He was "Toaster Guy" in the "Yard Sale" episode.
It’s almost a game at this point. You’re watching a classic re-run, and suddenly, there he is. This wasn't just luck; Kerkovich has a comedy background that many fans don't realize. He co-founded a comedy troupe called Summer of Tears back in 2004. They even won a jury prize at the U.S. Comedy Arts Festival in 2007.
That comedic timing is exactly why his more dramatic roles feel so grounded. He knows how to break the tension without making it feel like a forced punchline.
Rob Kerkovich Movies: From Monsters to Romantic Comedies
His film career is a bit of a mixed bag, but it’s got some cult favorites.
Did you know he was in Cloverfield? Yeah, the 2008 monster flick. He was just a "Party Goer," but it was one of his earliest entries into the industry.

Then you have things like The Rebound (2009) where he played Mitch, acting alongside Catherine Zeta-Jones. He also did the sequel Still Waiting... as Mason. These aren't necessarily Oscar-winners, but they showed his range early on. He could play the "best friend" or the "weird coworker" with total ease.
More recently, he’s leaned into indie territory. Loners (2019) saw him playing a federal agent, and Galaxy of Horrors (2017) let him flex some genre muscles.
The Hidden Credits: Writing and RPGs
Here is what most people get wrong about Rob: they think he’s just an actor.
Kerkovich is actually a writer too. He has writing credits on shows like Happy Endings, which explains why his delivery is often so sharp. He understands the mechanics of a joke.
Lately, he’s found a second life in the world of Tabletop RPGs. If you follow the Glass Cannon Podcast, you’ve heard him in the Call of Cthulhu series "Time for Chaos." It’s a total 180 from network television. It’s dark, improvisational, and shows a side of his creativity that doesn't always make it through the "CBS filter."

Why He’s Still Relevant in 2026
The industry has changed a lot, but "character actors" like Kerkovich are the backbone of everything we watch. He’s not the guy on the tabloid covers, and honestly, that’s probably why he’s stayed so employed.
He’s authentic. Whether he’s talking about his favorite spots in New Orleans—like "The Fly"—or deep-diving into a Lovecraftian horror podcast, he doesn't feel like a polished Hollywood product.
If you want to truly appreciate his work, don't just stick to the crime procedurals. Go back and find that Parks and Rec episode. Look up the Summer of Tears sketches. You’ll see a performer who is constantly subverting expectations.
If you're looking to binge-watch his work, start with Chasing Life for his more grounded drama or NCIS: New Orleans Season 3 and 4, which is where his character really starts to find his footing as a field agent.
Check out his voice work on podcasts if you want to see how he handles long-form storytelling without a script. It's a completely different vibe, but it's where his talent for character building really shines.
