It was 2008. Greece looked impossibly blue. Meryl Streep was jumping on a bed in dungarees, and Pierce Brosnan was—well, he was trying his absolute best to hit those high notes in "S.O.S."
People loved it. Or they hated it. But they definitely watched it.
When Mamma Mia! hit theaters, it wasn't just a jukebox musical; it was a cultural reset for the "vacation movie" genre. Then 2018 gave us the sequel, Mamma Mia! Here We Go Again, and suddenly we were all obsessed with Lily James’s energy and Cher showing up in a helicopter. But where are the stars of Mamma Mia today? Some have won Oscars. Others have retreated to quiet lives. A few are still dodging questions about a third movie that may or may not ever happen. Honestly, the career trajectories of this cast are as chaotic and delightful as a Donna Sheridan mood swing.
Meryl Streep: The Matriarch Who Moved On
Meryl doesn't do sequels. Usually.
She broke her own rule for a tiny, ghostly cameo in the second film because she loved the spirit of the first one so much. Since playing Donna, Streep hasn't slowed down, though she’s traded the Greek islands for more prestige drama and sharp-tongued comedy. You've seen her in The Post, Little Women, and more recently, making everyone uncomfortable in the best way possible in Only Murders in the Building.
She's Meryl. She’s the GOAT.
There’s a persistent rumor that she’d come back for a third film if the script was right. Producer Judy Craymer has hinted at it. But let’s be real: Donna’s story felt pretty final. Still, Meryl’s involvement in the original film is what gave the project "legs." It told Hollywood that A-list, "serious" actors could have fun without ruining their brand.
Amanda Seyfried: From Ingenue to Powerhouse
Amanda Seyfried was 22 when the first movie came out. She was the "girl with the big eyes" from Mean Girls.

Now? She’s an Emmy winner and an Oscar nominee.
The stars of Mamma Mia often get pigeonholed into that breezy, sun-soaked aesthetic, but Seyfried broke out of it hard. Her performance as Elizabeth Holmes in The Dropout was chilling. It was the polar opposite of Sophie Sheridan’s bubbly optimism. Off-screen, she’s moved away from the Hollywood grind. She lives on a farm in the Catskills with her husband, Thomas Sadoski, and a bunch of animals. It’s very "Donna Sheridan" of her, actually.
She’s been the most vocal about a third movie. She wants it. We want it. The only sticking point is the plot. How many times can Sophie find a new diary or a secret relative?
The Three Dads: Where Are Bill, Sam, and Harry?
The "Dad Trio" is arguably the soul of the franchise.
- Pierce Brosnan (Sam): He took a lot of heat for his singing. Like, a lot. But Pierce didn't care. He’s leaned into being a silver fox, appearing in Black Adam as Doctor Fate and focusing heavily on his painting. He recently had his first solo art exhibition in Los Angeles.
- Colin Firth (Harry): Post-Harry Bright, Firth won an Oscar for The King’s Speech. He’s stayed the king of the British gentleman archetype, though he did surprise everyone by becoming an action star in the Kingsman series.
- Stellan Skarsgård (Bill): Stellan is everywhere. If you aren't seeing him on Kalokairi, you’re seeing him in the Dune universe as the terrifying Baron Harkonnen or in the Star Wars world via Andor.
It’s wild to think that the same guy who played a goofy Swedish sailor is the same guy who plays some of the most intimidating villains in modern sci-fi. That’s range.
Lily James and the "New" Generation
The 2018 sequel succeeded because of Lily James. Period.
Taking over a role from Meryl Streep is a suicide mission for most actors. But Lily captured the essence of young Donna so perfectly that she became one of the most sought-after stars of Mamma Mia almost overnight. Since then, she’s transformed into Pamela Anderson for Pam & Tommy and starred in several period dramas.

She’s basically the bridge between the old guard and the new era of the franchise. Alongside her, stars like Jessica Keenan Wynn and Alexa Davies (young Tanya and Rosie) have stayed busy in the UK theater and TV circuits. They aren't "household names" in the US yet, but in the West End, they’re royalty.
The Christine Baranski Factor
We have to talk about Tanya.
Christine Baranski is a force of nature. While some actors might see a musical comedy as a "fun paycheck," Baranski treats Tanya with the same precision she brings to The Good Fight or The Gilded Age. She is the queen of the high-end procedural.
She recently joked that she’d be ready for Mamma Mia 3 tomorrow if it meant she got to go back to a Greek island and drink Ouzo with her friends. And that’s the thing about this cast—they actually like each other. Most "reunion" stories in Hollywood are PR fluff. This one feels different. Dominic Cooper and Amanda Seyfried even dated for years after the first movie, and despite the breakup, they still filmed the sequel together like total pros.
The Real Status of Mamma Mia 3
Is it happening?
Judy Craymer has gone on record saying it was always intended to be a trilogy. The songs are there—ABBA released Voyage, their first new album in 40 years, back in 2021. There is fresh material to use. The main hurdle is the cast’s schedules. You’re trying to coordinate Meryl Streep, Cher, Amanda Seyfried, and a bunch of MCU/Star Wars actors.
It’s a logistical nightmare.

Also, the script needs to make sense. Here We Go Again used the flashback device to tell Donna’s origin. A third film would likely have to focus on Sophie’s child or perhaps a "pre-prequel." Or, they could just ignore logic entirely. Honestly, fans wouldn't mind. People don't watch these movies for the tight plotting; they watch for the vibes.
Why We Are Still Obsessed
There is a psychological comfort to this specific group of actors. They represent a "pre-algorithm" type of stardom. They feel like real people who happened to get stuck on an island together.
- The chemistry isn't manufactured.
- The singing is imperfect (looking at you, Pierce).
- The joy is palpable.
In an era of gritty reboots and dark cinematic universes, the stars of Mamma Mia offer something rare: pure, unadulterated escapism.
What You Should Do Next
If you’re looking to keep up with the cast or dive deeper into the lore, don’t just wait for a trailer that might never come.
Track the ABBA Voyage show in London. While the actors aren't there physically, the technology used for the "Abba-tars" is the same tech that many believe will eventually be used to de-age the cast if they ever decide to do a full prequel.
Follow the "Mamma Mia" producers on social media. Judy Craymer is the one who drops the real breadcrumbs.
Watch "The Dropout" or "Andor." Seeing the dramatic range of Amanda Seyfried and Stellan Skarsgård makes re-watching them sing "Dancing Queen" even more impressive. It reminds you that these are top-tier professionals who just happened to make a movie about a girl with three dads.
Keep an eye on the trades (Variety, Hollywood Reporter) for any mention of "Ol Parker" or "Judy Craymer." If a third movie gets greenlit, it’ll break there first, likely around a major anniversary of the original 1999 stage play. Until then, we’ll always have the 2008 soundtrack and Pierce Brosnan’s questionable—but enthusiastic—vocals.
