It was 2001. Fantasy wasn't the box-office juggernaut it is today. The Lord of the Rings was only just hitting theaters, and Game of Thrones was still a decade away from becoming a household name. Then came TNT’s miniseries adaptation of Marion Zimmer Bradley’s massive novel. Honestly, the cast of the mists of avalon was a bit of a miracle. Looking back, it’s wild to see how many heavy hitters were packed into a four-hour television event.
Most Arthurian retellings focus on the guys. You get a lot of clanging swords and Merlin doing magic in a cave. But this was different. This was the story told through the eyes of the women—Morgaine, Viviane, and Gwenhwyfar. To make that work, you needed actors who could carry the weight of a changing world, transitioning from the old Pagan ways to the rise of Christianity.
The powerhouse women at the heart of Camelot
Julianna Margulies took on the role of Morgaine (Morgan le Fay). She had just come off her massive run on ER as Nurse Carol Hathaway. People were used to seeing her in scrubs, but here she was in flowing robes and mystical tattoos. She brought this really specific, grounded melancholy to the character. Morgaine isn't a villain here; she's a tragic figure caught between two worlds. Margulies played her with a quiet intensity that sort of anchors the whole production.
Then you have Anjelica Huston. Seriously, who else could play the Lady of the Lake?
Huston is royalty. As Viviane, High Priestess of Avalon, she is terrifying and maternal all at once. There’s this one scene where she’s basically orchestrating the future of Britain, and you realize she’s playing a much longer game than any of the men on the screen. Huston has this natural authority—that "Huston gaze"—that makes you believe she actually could control the mists.
Joan Allen played Morgause, the ambitious sister. If you know Joan Allen from her Oscar-nominated roles, you know she’s a master of the "steel magnolia" vibe. She’s cold, calculating, and provides the perfect foil to Margulies’ more empathetic Morgaine. The dynamic between these three women is actually the engine of the show.

Breaking down the supporting players
It wasn't just the leads. The secondary characters in the cast of the mists of avalon were equally stacked.
- Edward Atterton as Arthur: He had to play the king as a man torn between his sister, his wife, and his duty. It’s a thankless job sometimes, playing the "good" guy, but he made Arthur feel human rather than a legend.
- Samantha Mathis as Gwenhwyfar: She’s often the most polarizing character for fans. Mathis played her with a desperate, religious fervor that felt very real. You kind of hate her for what she does to the old ways, but you also feel for her trapped in her own fear.
- Hans Matheson as Mordred: He brought a weird, wiry energy to the role. He looked like he was vibrating with resentment.
- Michael Vartan as Lancelot: Before he was the heartthrob on Alias, he was the primary romantic complication here.
Why the acting held up (and where it didn't)
Let’s be real for a second. The CGI from 2001 has aged like milk. The "mists" sometimes look like someone left a fog machine on too high in a cramped studio. But the acting? That’s why people still watch this.
You’ve got a cast that treated the material with total sincerity. In a lot of early 2000s TV movies, actors would "chew the scenery." They’d go over the top because it was fantasy. But the cast of the mists of avalon played it like a historical drama. They leaned into the interpersonal trauma. When Morgaine realizes the sacrifice she has to make, Margulies doesn't scream at the sky; she just looks hollowed out. That’s the difference.
The Merlin problem
In this version, Merlin isn’t a wizard with a pointy hat. He’s the Taliesin, played by Michael Byrne. It’s a much more druidic, grounded interpretation. Honestly, it’s refreshing. He feels like a scholar and a diplomat. It makes the "magic" feel like it’s just a deeper understanding of nature rather than sparkly special effects.
The controversy behind the scenes
It is impossible to talk about the cast of the mists of avalon today without acknowledging the shadow over the source material. Since the miniseries aired, the horrific allegations against the author, Marion Zimmer Bradley, and her husband have come to light. It’s created a massive rift in how people view the story.

Many fans struggle with this. How do you separate the art from the artist? The actors, of course, had no part in that history. They were hired to bring a feminist retelling of a classic myth to life. For many viewers, the performances of Margulies and Huston have become a way to reclaim the story’s themes of female agency and spiritual transition without necessarily honoring the woman who wrote the book. It’s a complicated legacy.
Where are they now?
If you look at the cast of the mists of avalon today, it’s like a "who’s who" of prestige television.
- Julianna Margulies: Went on to star in The Good Wife, winning multiple Emmys and becoming one of the highest-paid actresses on TV.
- Anjelica Huston: Continued her legendary career, appearing in everything from The Royal Tenenbaums to John Wick: Chapter 3.
- Joan Allen: Stayed a powerhouse in film, notably in the Bourne franchise.
- Michael Vartan: Became a TV staple through Alias and Hawthorne.
It’s rare for a miniseries to have this much "bench strength." Usually, you get one or two stars and a lot of fillers. Here, even the smaller roles were filled by actors who would go on to lead their own shows.
The impact on the fantasy genre
Before The Mists of Avalon, fantasy on TV was often campy. Think Xena or Hercules. Not that those weren't great, but they didn't aim for "prestige." This miniseries tried to be a serious drama. It paved the way for the high-budget, serious-toned fantasy we see now on HBO and Netflix. It proved there was an audience for adult-oriented, character-driven mythology.
The cast of the mists of avalon had to sell the idea that these myths mattered. They had to make the religious conflict between the Goddess and the New God feel like a life-or-death struggle. Without the gravitas of actors like Huston or Allen, the whole thing might have collapsed under the weight of its own velvet capes.

Practical takeaways for fans of the series
If you’re revisiting the show or discovering it for the first time, keep these things in mind to get the most out of the experience:
- Focus on the eyes: The cinematography relies heavily on close-ups. The actors do a lot of "acting without talking," especially Margulies.
- Watch the costumes: The wardrobe was designed to reflect the characters' spiritual states. Notice how Morgaine's colors shift as she moves further from Avalon.
- Check the runtime: It was originally a two-part event. It’s best watched in two chunks to respect the pacing the director, Uli Edel, intended.
- Look for the cameos: There are several British character actors in the background who have since popped up in Downton Abbey and The Crown.
The cast of the mists of avalon remains the gold standard for how to cast an ensemble for a literary adaptation. They took a dense, controversial, and deeply emotional book and made it accessible. While the special effects might make you chuckle in 2026, the performances remain remarkably sharp.
To truly appreciate the performances, compare this version to the 1981 film Excalibur or the more recent The Green Knight. You'll see that the 2001 miniseries holds a unique middle ground—it's more emotional than the former and more literal than the latter. It’s a specific snapshot of a time when TV was just starting to realize it could be as big and bold as the movies.
If you want to dive deeper into the production, look for the "making-of" featurettes often found on the legacy DVD releases. They provide a lot of context on how they filmed in the Czech Republic to mimic the look of ancient Britain. Watching the cast handle the cold and the mud while trying to look like mystical beings adds a whole new layer of respect for their work.
