This complete guide to the cast of plebs covers every major performer in the British sitcom Plebs, the ITV2 comedy that followed three young men trying to make their way in ancient Rome. Plebs ran for five series between 2013 and 2019, plus a feature-length special, and it built a loyal audience with its modern take on the ancient world: flat-shares, office politics, dating disasters, and hangovers, all played out in togas. The cast mixed established comedy talent with newcomers, and several of its members went on to much bigger things.
The premise was simple and immediately funny. Marcus, Stylax, and Grumio shared a flat in Rome and worked low-status jobs while dreaming of better lives. The show treated ancient Rome like a modern city, with slave agencies, bathhouses standing in for gyms, and landlords who never fixed anything. That anachronistic approach only worked because the cast played it straight, treating Roman life as completely normal, and the ensemble’s chemistry is the main reason the show lasted as long as it did.

| Karl Theobald | Landlord | 1–5 | The flat’s exasperating landlord |
The most important cast change came after series three, when Joel Fry left and Jonathan Pointing joined as Jason. That switch is the dividing line for many fans: the first three series are the original trio, and the last two are a new configuration built around Marcus, Grumio, and Jason. Both versions work, but they have different energy, and this guide covers both.
The Original Trio: Marcus, Stylax, and Grumio
Tom Rosenthal’s Marcus Gallo was the show’s anchor. Marcus was ambitious, status-obsessed, and constantly scheming his way into better jobs and better parties, usually with embarrassing results. Rosenthal played him with a wonderful mix of confidence and panic, and Marcus’s voiceover-style asides and direct-to-camera moments gave the show much of its comic rhythm. Rosenthal stayed for the entire run, and his performance is the most consistent thread across all five series.
Joel Fry’s Stylax was the trio’s wild card: handsome, impulsive, and devoted to pleasure, whether that meant women, wine, or avoiding work. Fry played him with infectious energy, and Stylax’s schemes were often the episode’s engine. His departure after series three was written as Stylax leaving Rome, and the show never quite replaced his particular brand of chaos, though it found a different kind of comedy in his successor.
Ryan Sampson’s Grumio was the show’s secret weapon. As Marcus’s slave, Grumio was technically the lowest-status character, but Sampson made him the funniest and often the wisest person on screen. Grumio’s loyalty to Marcus, his terrible luck, and his unexpected moments of insight made him a fan favourite, and Sampson’s physical comedy and timing carried many episodes. Like Rosenthal, he stayed for the whole run and the special.
The Jason Era: How the Cast of Plebs Changed
When Jonathan Pointing joined in series four as Jason, the show deliberately did not try to clone Stylax. Jason was a different character: a cheerful, slightly naive newcomer from the provinces whose optimism clashed with Marcus’s cynicism. Pointing’s warmth gave the later series a softer, sillier tone, and the Marcus-Grumio-Jason dynamic became its own thing rather than a pale copy of the original trio.
The change also let the writers refresh the show’s jokes. New flatmate rituals, new workplace storylines, and Jason’s outsider perspective on Roman life gave series four and five their own identity. Fans still debate which era is better, but the fact that the show survived a major cast change and produced two more strong series is a tribute to the remaining cast and to Pointing’s fit with the ensemble.

The Supporting Cast of Plebs
Doon Mackichan’s Flavia was one of the show’s great creations: a sharp, worldly woman who ran a bathhouse and served as a mentor, occasional employer, and source of withering put-downs. Mackichan, already a respected comedy performer, brought authority to every scene, and Flavia’s friendship with the lads gave the show an emotional anchor beyond the flat.
Tom Basden’s Aurelius was the perfect foil: rich, smug, and effortlessly successful, everything Marcus wanted to be. Basden, who also co-created the show, played Aurelius with just enough charm that you could see why people tolerated him. Karl Theobald’s landlord, meanwhile, was a running joke in himself, forever turning up to demand rent or complain about damage, and his exasperated patience with the flatmates never got old.
Recurring Faces and Guest Stars
Plebs also featured a strong bench of guest performers across its run, including well-known British comedy faces in one-off roles as employers, love interests, officials, and rivals. Ellie Taylor’s Gloria, introduced in series two, became an important recurring character as a colleague and love interest, and her run gave Marcus’s romantic storylines more weight. The guest casting was one of the show’s quiet strengths: because Rome was a whole city, almost any comic situation could walk through the door.
Where the Cast of Plebs Went Next
Several members of the cast went on to prominent work after Plebs. Joel Fry became a familiar face in major film and television, including roles in Game of Thrones, Yesterday, and Cruella, and his post-Plebs career is the most high-profile of the original trio. Tom Rosenthal continued in comedy, including the series Friday Night Dinner, where his performance as Jonny became another fan favourite. Ryan Sampson appeared in further television comedy and drama, and Jonathan Pointing continued to work in comedy and acting after his Jason run.
Doon Mackichan and Tom Basden were already established before Plebs and remained busy afterwards, with Basden continuing to write and perform. The show’s legacy is visible in the way its cast members keep turning up across British comedy: once you know Plebs, you start spotting its alumni everywhere, which is a sign of how well the show cast its ensemble.
Why This Cast Worked So Well
The cast succeeded because the three leads had genuinely different comic energies that balanced each other. Rosenthal’s anxious ambition, Fry’s reckless charm, and Sampson’s put-upon loyalty created a triangle where any two characters could carry a scene and the third could walk in and change it. When Pointing replaced Fry, the triangle changed shape rather than breaking: Jason’s optimism against Marcus’s scheming and Grumio’s suffering produced a new set of jokes.
The supporting cast mattered just as much. Mackichan, Basden, and Theobald gave the world around the flat its texture, so Rome felt like a real place with real hierarchies rather than a backdrop. That depth is why the show could run for five series without repeating itself: the ensemble was large enough to generate new combinations, and the writers used all of it.
The feature-length special, Plebs: Soldiers of Rome, gave the cast one final outing and a proper send-off, reuniting Rosenthal, Sampson, and Pointing with Mackichan and Basden for a story that took the flatmates out of Rome and into military life. The special worked because it leaned on everything the cast had built over five series: Marcus’s scheming, Grumio’s suffering, Jason’s optimism, and the supporting players’ exasperation with all three. For new viewers, it is best watched after the fifth series, since its jokes reward familiarity with the characters, but it also stands alone as a funny farewell to the ensemble.

Conclusion
The cast of plebs is a case study in ensemble comedy done right: three leads with contrasting energies, a supporting cast that made ancient Rome feel lived-in, and a successful mid-run reinvention when Joel Fry left and Jonathan Pointing arrived. Whether you prefer the original trio or the Jason era, the show’s strength was always its performers, and its alumni have gone on to populate British comedy well beyond the series itself. Start with series one for the classic line-up, and keep watching past series three to see how a great cast adapts without losing its identity.
