It is 1920s Italy. The sun is aggressive, the cocktails are cold, and the political tension is thick enough to cut with a butter knife. But honestly, most of us aren't just watching for the vintage luggage or the sweeping views of the Riviera. We’re watching for the people. The cast of Hotel Portofino isn't just a collection of actors in period costumes; they are the engine of a show that manages to feel like a cozy mystery and a high-stakes historical drama all at once. If you’ve ever found yourself googling "where have I seen him before?" while watching Cecil Ainsworth scheme, you aren't alone.
The Anchors: Natascha McElhone and the Weight of Bella
Natascha McElhone is the heartbeat here. Period.
As Bella Ainsworth, she has to carry the massive burden of being the "sensible one" in a family that is, frankly, a bit of a disaster. McElhone brings a specific kind of weary elegance to the role that feels incredibly lived-in. You might remember her from Californication or The Truman Show, but this is different. In Hotel Portofino, she isn't just a love interest or a supporting player. She is the literal foundation.
Her performance matters because she has to balance the "English Rose" exterior with the grit of a woman running a business in Mussolini’s Italy. It’s a tightrope walk. One wrong move and the character becomes a boring martyr. But McElhone keeps her sharp. You see the frustration in her eyes when her husband, Cecil, starts his latest nonsense. Speaking of Cecil, let’s talk about Mark Umbers.
Umbers is fascinating because he plays a character you’re supposed to dislike, yet you can’t look away. Cecil is charming. He’s also a manipulative, entitled parasite. It takes a very specific type of actor to make that cocktail drinkable. Umbers has a theater background—lots of Shakespeare and high-end drama—and it shows in his posture. He wears a linen suit like he was born in it, which makes his moral failings feel even more jarring.

The Next Generation: Alice, Lucian, and the Emotional Stakes
The younger cast of Hotel Portofino members have the hardest job. They have to represent the "Lost Generation" without being total clichés.
Olivia Morris plays Alice Ainsworth. If she looks familiar, it’s probably because she was the female lead in the massive Indian blockbuster RRR. Switching from a high-octane Tollywood action flick to a nuanced British period drama is quite the pivot. Alice is a widow, a mother, and someone deeply constrained by the expectations of the 1920s. Morris plays her with a simmering resentment that feels very modern, even if her clothes are strictly vintage.
Then there is Lucian, played by Oliver Dench. Yes, he is related to that Dench (he’s Judi Dench’s great-nephew).
Lucian is the soul of the show. He’s a veteran of the Great War, and Dench plays that trauma with a quiet, shaky hand. He doesn't do a lot of "big acting" with shouting or crying. Instead, it’s in the way he avoids eye contact or how he throws himself into his painting. It’s a subtle performance that grounds the show's more soap-opera leaning moments. His chemistry with Constanza (Elizabeth Carling) and the rest of the staff adds a layer of "upstairs-downstairs" tension that fans of Downton Abbey will recognize immediately, though it feels a bit saltier here.

The Supporting Players You Need to Know
A show like this lives or dies by its ensemble. You can't just have the leads doing all the work.
- Assad Zaman as Anish Sengupta: Anish is Lucian’s close friend and a doctor. Zaman plays him with an incredible amount of dignity. His storyline explores the intersection of race, sexuality, and the medical profession in a time when being "different" was literally dangerous.
- Louisa Binder as Constance March: The "new girl" at the hotel. She’s the audience surrogate in many ways. We see the hotel through her eyes. Binder brings a freshness to the role that prevents the show from feeling too stuffy.
- Pasquale Esposito as Vincenzo Danioni: Every show needs a villain you love to hate. Danioni is the local fascist official who makes Bella’s life a living hell. Esposito is terrifying because he’s so calm. He doesn't twirl a mustache; he just sits there and waits for you to fail.
Why This Specific Ensemble Works Better Than Other Period Dramas
There is a weird phenomenon with period pieces. Often, the actors feel like they are "playing dress-up." They move stiffly. They speak like they’re reading from a dusty textbook.
The cast of Hotel Portofino avoids this. Why? Because the casting directors (shout out to Kelly Valentine Hendry) looked for actors who could handle the "modern" subtext. This isn't just a show about the 1920s; it’s a show about people dealing with trauma, financial ruin, and political extremism—things we’re still talking about today.
Take Lily Frazer, who plays Claudine Pascal. She brings a blast of American energy and Jazz Age glamour to the Italian coast. She’s a Black woman navigating a very white, very European space, and Frazer plays that with a "take me as I am" attitude that is incredibly refreshing. She isn't a victim; she’s a force of nature.

The Challenges of Season 3 and Beyond
As the show has progressed into its third season, the cast has had to evolve. Characters who were once "the kids" are now making life-altering decisions. The stakes have shifted from "will the hotel stay open?" to "will these people survive the rise of Fascism?"
This shift requires the actors to dig deeper. It’s no longer about whether a guest liked their breakfast; it’s about hiding people from the Blackshirts. Natascha McElhone, in particular, has had to show a much darker, more desperate side of Bella. It’s impressive to watch an actor peel back the layers of a character over several years.
How to Follow the Cast Outside the Show
If you’ve fallen in love with these performers, you’re in luck. Most of them are working across some pretty big projects.
- Natascha McElhone: Check out Halo if you want to see her in a completely different, sci-fi setting.
- Assad Zaman: He’s been making waves in the Interview with the Vampire TV series (he’s brilliant in it).
- Mark Umbers: Still a staple of the British stage, often seen in West End productions.
Moving Forward with Hotel Portofino
Watching the cast of Hotel Portofino is a lesson in ensemble chemistry. To get the most out of your next rewatch, try focusing on the background characters—the kitchen staff and the local Italians. The show does a great job of making the town of Portofino feel like a character itself, and the local casting is a big part of that.
If you're looking for your next steps after finishing the latest season:
- Look for the "Making Of" specials: These often highlight the grueling shoot schedules in Croatia (which doubles for Italy) and how the cast bonded.
- Check out the original novel: Written by J.P. O'Connell, it gives a bit more internal monologue for the characters that the actors then had to translate to the screen.
- Follow the costume designers: Look up Lou Bone's work on the show. The actors often mention how the restrictive clothing of the era helped them get into character.
The brilliance of this cast is that they make a high-society hotel in 1926 feel like a place you’ve actually visited. They bridge the gap between "historical figure" and "real person." That’s why we keep checking back in.
