You know that feeling when an actor walks onto a screen and suddenly everything else just... fades out? That's Siân Phillips. Honestly, she has this way of commanding a room—or a Roman palace, or a spice-rich desert planet—that makes you forget anyone else is even in the scene.
Most people recognize her as the terrifyingly brilliant Livia from the 1976 BBC masterpiece I, Claudius. She didn't just play a villain; she basically invented the archetype for the modern TV anti-heroine. If you think the "prestige TV" era started with The Sopranos, you've clearly never seen Siân Phillips casually poisoning a bowl of figs while discussing the future of the Roman Empire.
The Roles That Defined Siân Phillips Movies and TV Shows
When we talk about siân phillips movies and tv shows, the conversation usually starts with that Bafta-winning turn as Livia. It was a role that defined a decade. But if you look closer, her career is a wild, unpredictable map of high drama, cult sci-fi, and heartbreaking period pieces.
She's one of those rare performers who can transition from the Royal Academy of Dramatic Art (RADA) to a David Lynch set without breaking a sweat.
From the Valleys to the Stars
Phillips was born in Gwaun-Cae-Gurwen, Wales, in 1933. She was a child star on the radio by age 11. That's a long time to be in the spotlight. By the time she was making her mark in film, she was already a seasoned pro.
In the 1960s, she popped up in Becket (1964) alongside her then-husband Peter O’Toole and Richard Burton. Imagine that dinner table. She played Gwendolen, and while it was a supporting role, you can see the flinty intelligence that would later make her a star.

Then came Goodbye, Mr. Chips in 1969. She was Ursula Mossbank, a role that earned her a Golden Globe nomination. It was proof that she could handle the "big" Hollywood musical energy just as well as the intimate stage work she loved.
The Cult Classics You Probably Forgot
If you're a sci-fi nerd, you know her. You might not know you know her, but you do.
In 1984, David Lynch cast her as the Reverend Mother Gaius Helen Mohiam in Dune. It’s a polarizing movie, sure, but her performance? Iconic. She and Lynch actually both came up with the idea for her character's striking bald look independently. That’s the kind of creative synergy you don’t see often. She brought a certain... ancient weight to the role. When she holds that gom jabbar to Paul Atreides' neck, you actually believe she’ll use it.
- Clash of the Titans (1981): She played Queen Cassiopeia. It’s pure 80s cheese in the best way possible, and she leans into it with absolute grace.
- Ewoks: The Battle for Endor (1985): Yes, she was in a Star Wars spin-off. She played Charal, a night sister/witch. It’s a far cry from Ibsen, but she’s clearly having a blast.
- La Femme Nikita: For the Gen-X crowd, she was Adrian, the renegade founder of Section One.
Why She’s More Than Just a "Period Piece" Actor
A lot of critics pigeonhole her into historical drama. That's a mistake. While she was incredible as Emmeline Pankhurst in Shoulder to Shoulder (1974) and Beth Morgan in How Green Was My Valley (1975), she’s never been afraid to get weird.
Take her recent work. In 2024, at the age of 90, she appeared in the Doctor Who episode "73 Yards." She played Enid Meadows. It was a haunting, quiet performance that reminded everyone why she’s still getting booked 70 years into her career.

She also showed up in Good Omens season 2 and McDonald & Dodds. She doesn't "retire" in the traditional sense. She just finds more interesting ways to exist on screen.
The Bafta Legacy
You can't mention siân phillips movies and tv shows without talking about the hardware. She won the 1977 BAFTA for Best Actress for both I, Claudius and How Green Was My Valley. Think about the range required for that. On one hand, you have a ruthless, power-hungry Empress. On the other, a hardworking mother in a Welsh coal-mining village. Most actors would kill for one of those roles; she nailed both in the same year.
What Most People Get Wrong
People often think she was "overshadowed" by Peter O’Toole during their marriage. Honestly? That’s nonsense. If anything, her career has had more longevity and variety. While O’Toole was the wild-eyed leading man, Phillips was the architect. She built a career on precision.
She once said in an interview with The Guardian that she turned down film contracts early on because she was "trained for the theatre." She eventually embraced the camera, but she never lost that stage discipline. That's why her television roles feel so weighty. They aren't just "content"—they’re performances.
"You have to live on the knife-edge of insecurity." — Saunders Lewis (Advice given to Siân Phillips early in her career).

She took that advice to heart. Whether she’s playing a faith healer in Ballykissangel or a grandmother in the miniseries Attila, there's always a sense that she's taking a risk.
Seeing the Legend Today
If you want to dive into the best of siân phillips movies and tv shows, don't just stick to the hits.
- Start with I, Claudius. It’s on various streaming platforms (or find the DVD, it’s worth it). Watch how she uses her eyes. She can kill a man with a glance.
- Check out The Age of Innocence (1993). She plays Mrs. Archer, and it’s a masterclass in subtlety.
- Find her 2024 Doctor Who appearance. It's proof that talent doesn't have an expiration date.
- Look for the 1975 How Green Was My Valley. It’s a heart-wrencher, especially if you have any Welsh roots.
Basically, the woman is a force of nature. From the West End to the outer reaches of the galaxy, Siân Phillips has done it all. And the best part? She’s still doing it.
If you're looking for a binge-watch that actually makes you think, start with her 1970s BBC work. It’s better than 90% of what’s on Netflix right now.
To truly appreciate the scope of her work, your next step should be to watch the first two episodes of I, Claudius back-to-back. Pay attention to how her character, Livia, slowly tightens her grip on the household. It’s a masterclass in pacing that you won’t find in modern "bingeable" shows. After that, compare that coldness to her warmth in How Green Was My Valley to see why she’s considered one of the greatest to ever do it.
