Which Actors From The 100 Are In Other Shows?

Curious who plays young Sheldon beyond 'Young Sheldon'? I got hooked on Iain Armitage early on, and he's done more than just the CBS sitcom. Before and alongside his breakout role as Sheldon Cooper, he popped up in the HBO drama 'Big Little Lies' playing Ziggy, which was a neat chance to watch him in a very different tone — more grounded and emotional than the comedic timing he shows on 'Young Sheldon'. Outside TV series, he's crossed over to film and voice work: he has credits in the family drama 'The Glass Castle' and lent his voice in the animated movie 'Scoob!'. He also started out building a profile online with his charming theatre-review videos, which is how a lot of people first noticed his personality and instincts. I love tracking his work because he seems to pick projects that stretch him, and it’s fun to watch that growth up on screen.

The cast of 'The 100' is packed with talent, and over its seven-season run, we got to see some incredible performances. Eliza Taylor leads the pack as Clarke Griffin, the show's moral compass and protagonist who’s constantly forced to make impossible choices. Bob Morley brings depth to Bellamy Blake, whose arc from rebellious big brother to a leader torn by guilt is one of the show’s highlights. Then there’s Marie Avgeropoulos as Octavia Blake, who undergoes one of the most dramatic transformations—from a sheltered girl to the ruthless 'Bloodreina.' Lindsey Morgan’s Raven Reyes is another standout, with her genius-level engineering skills and resilience making her a fan favorite. Supporting roles are just as memorable. Richard Harmon’s John Murphy starts off as a selfish survivor but grows into someone far more complex, while Paige Turco’s Dr. Abigail Griffin and Henry Ian Cusick’s Marcus Kane bring gravitas to the adult leadership dynamics. Tasya Teles’s Echo and Shannon Kook’s Jordan Green add layers to the later seasons, and let’s not forget Adina Porter’s Indra, the fierce Grounder warrior who becomes a key ally. The show’s ensemble cast really sells the high-stakes survival drama, and each actor brings something unique to their role. It’s one of those rare series where even the side characters leave a lasting impression—like Christopher Larkin’s Monty Green, whose quiet heroism steals hearts. I still get chills thinking about some of their performances, especially in those gut-wrenching final seasons.

Oh, 'The 100' had such a dynamic cast! Eliza Taylor absolutely killed it as Clarke Griffin—her character arc from privileged Ark kid to hardened leader was insane. Bob Morley’s Bellamy Blake went from ‘whatever the hell we want’ to this deeply layered protector, and Marie Avgeropoulos as Octavia? Iconic. Lindsey Morgan’s Raven was the tech genius we all rooted for, and Richard Harmon’s Murphy? Surprisingly the best redemption story. Then there’s Henry Ian Cusick as Kane, whose moral dilemmas were chef’s kiss, and Paige Turco’s Abby Griffin, who balanced mom vibes with medical badassery. Let’s not forget Tasya Teles’s Echo, who evolved from enemy to fan favorite. The show wouldn’t be the same without this crew—each actor brought something raw and unforgettable to their roles.

The casting in 'The 100' was honestly one of its strongest points—so many talented faces brought this post-apocalyptic world to life! Eliza Taylor crushed it as Clarke Griffin, balancing leadership with vulnerability, while Bob Morley’s Bellamy Blake had that perfect mix of rugged charm and emotional depth. Marie Avgeropoulos as Octavia? Iconic. Her transformation from the girl under the floor to Skairipa was jaw-dropping. Lindsey Morgan’s Raven added wit and resilience, and Richard Harmon’s Murphy? Love-to-hate him, then just love him. The supporting cast, like Isaiah Washington’s Chancellor Jaha and Paige Turco’s Abby, grounded the sci-fi drama with gravitas. Even the lesser-known actors like Tasya Teles (Echo) and Jarod Joseph (Miller) left a mark. It’s wild how this show made you root for—or scream at—every character. What’s cool is how the actors grew alongside their roles. Eliza and Bob’s chemistry evolved so naturally, and Henry Ian Cusick’s Kane went from icy politician to fan favorite. Devon Bostick’s Jasper had this heartbreaking arc that still stings. And let’s not forget Adina Porter’s Indra, who stole every scene with warrior mom energy. The ensemble felt like a dysfunctional family, which made the brutal stakes hit harder. Even the Grounders and Mountain Men actors, like Ricky Whittle (Lincoln) and Zach McGowan (Roan), added layers to the world. Seriously, rewatch any season, and you’ll spot new nuances in their performances.

Jaehan's filmography is such a fun rabbit hole to dive into! Beyond his breakout roles, he's had some real gems. I adore his work in 'The Silent Sea'—his portrayal of a conflicted astronaut was gripping, balancing vulnerability and resolve. Then there's 'D.P.', where he played a military police officer; the raw intensity he brought to that role still gives me chills. What surprised me was discovering his earlier work in indie films like 'Moral Sense'. He's got this knack for picking projects that challenge norms, whether it's sci-fi thrillers or dark comedies. His range is wild—from brooding dramas to lighthearted web series like 'Love Revolution'. Honestly, every time I think I've seen all his stuff, I stumble onto another hidden treasure.

Oh, absolutely! The cast of 'The Walking Dead' has popped up in so many other shows, it's like a fun game of 'Where's Waldo?' but with actors. Andrew Lincoln, who played Rick Grimes, had this iconic role in a British romantic drama called 'This Life' way before he was battling zombies. Then there's Norman Reedus (Daryl Dixon), who's now leading his own spin-off, 'The Walking Dead: Daryl Dixon,' but also starred in 'The Boondock Saints' films—totally different vibe, but he’s just as intense. Melissa McBride (Carol) had a recurring role in 'The Mist,' which was another horror-ish series, and she brought that same quiet strength to her character there. Danai Gurira (Michonne) is a powerhouse—she’s not just in the Marvel universe as Okoye in 'Black Panther,' but also had a role in 'Treme,' a show about post-Katrina New Orleans. Steven Yeun (Glenn) has been killing it in 'Invincible' as the voice of Mark Grayson, and his dramatic turn in 'BEEF' was chef’s kiss. Lauren Cohan (Maggie) jumped into 'Whiskey Cavalier,' a spy comedy-drama, and honestly, it was refreshing to see her in something lighter after all the zombie apocalypse trauma. It’s wild how many of them have branched out into totally different genres!

It's wild how many 'The 100' alumni are still killing it in Hollywood! Eliza Taylor (Clarke) has been popping up in indie films and even directed a short recently—she’s got this quiet, intense vibe that translates so well behind the camera too. Bob Morley (Bellamy) took a break but came back swinging with guest roles in Aussie dramas; his rugged charm hasn’t faded one bit. Marie Avgeropoulos (Octavia) is my personal favorite—she’s been in action flicks like 'Trickster' and still does that fierce warrior thing better than anyone. Lindsey Morgan (Raven) just starred in a sci-fi series called 'The Ark,' proving she’s still the queen of tech genius roles. And Richard Harmon (Murphy)? That guy’s everywhere—from horror to crime shows, always playing the lovable rogue. Even the younger cast like Lola Flanery (Madi) booked a lead in a fantasy series. It’s like the whole cast absorbed the show’s survival skills and applied them to their careers! What’s cool is how they’ve all branched into different genres while keeping that gritty 'The 100' energy. Tasya Teles (Echo) does voice work for games now, which suits her smoky voice perfectly. Christopher Larkin (Monty) went into producing, and Henry Ian Cusick (Kane) still lands major network roles—dude’s ageless. I love spotting them in random projects; it’s like a scavenger hunt for post-apocalyptic actors thriving in normal clothes.

Man, hearing about actors leaving shows always hits differently. I was totally invested in 'The Office' when Steve Carell left, and it felt like the heart of the show was gone. From what I gathered, his departure was planned—he always intended to leave after seven seasons, but fans (including me) hoped he’d stay. The showrunners respected his decision, though, and didn’t force a return. Sometimes, actors just want to explore new roles or take a break, and that’s fair. Still, it’s tough when a character you love bows out. Shows often struggle to fill that void, and it makes you appreciate how much one actor can shape a series. On the flip side, some exits are messier—contract disputes, creative differences, or even personal reasons. Like when Charlie Sheen left 'Two and a Half Men.' That was pure drama, with public feuds and network reshuffling. It’s wild how behind-the-scenes tensions can spill into the story. Either way, when a key actor leaves, it’s a gamble—will the show adapt or crumble? 'The Office' tried, but it wasn’t the same. Makes you wonder what could’ve been if they’d convinced him to stay.

The cast of 'The 100' had quite a rollercoaster journey over the show's seven-season run. Main characters like Clarke (Eliza Taylor), Bellamy (Bob Morley), and Octavia (Marie Avgeropoulos) appeared in most seasons, though their arcs had some wild twists—especially in later seasons where survival got even messier. Some fan favorites, like Lincoln ( Ricky Whittle), had shorter stays due to storyline choices, while others, like John Murphy (Richard Harmon), became unexpected survivors who stuck around till the bitter end. The show’s ensemble cast shifted a lot as new factions and threats emerged, but the core group’s dynamics kept fans hooked. By the final season, the roster felt almost nostalgic compared to the early days of dropships and grounder politics. It’s one of those rare series where even minor characters left a lasting impression, making the full seven-season ride feel like a proper saga—flaws, time jumps, and all.

The 100 has such a memorable ensemble cast that it's hard to pick favorites, but let me gush about the core actors who brought the post-apocalyptic world to life. Eliza Taylor absolutely owned the screen as Clarke Griffin, the reluctant leader whose decisions shaped the entire series. Alongside her, Bob Morley delivered a powerhouse performance as Bellamy Blake, with that perfect balance of rugged charm and emotional depth. Their dynamic—whether as allies, rivals, or something more—kept me glued to every season. Then there’s Marie Avgeropoulos as Octavia Blake, whose transformation from sheltered girl to brutal warrior was one of the show’s most gripping arcs. Lindsey Morgan’s Raven Reyes stole scenes with her wit and resilience, while Richard Harmon’s morally complex John Murphy became the character I loved to hate (and eventually just loved). Devon Bostick’s Jasper brought heartbreak with his tragic journey, and Paige Turco’s Dr. Abby Griffin added gravitas as Clarke’s mother. Oh, and how could I forget Isaiah Washington’s Chancellor Jaha, whose descent into obsession was chilling? The cast’s chemistry made even the wildest plot twists feel grounded—I still miss tuning in to their chaos every week.
