From Meryl to Cher, Bask in the Glory of Mamma Mia! Here We Go Again's A-List Cast

The film icon will bless our ears once again as she belts out more ABBA tunes as Donna.

The Baby Driver alum is playing the younger version of Streep's character, Donna!

Christine Baranski will take a break from The Good Fight to reprise her role as Tanya, one of Donna's BFFs and one-third of the Dynamos.

After smaller roles in shows like The Mysteries of Laura and Billion, Jessica Keenan Wynn will play young Tanya in the sequel. We can definitely see the resemblance between the two!

It's hard not to love former Dynamo bandmate Rosie, so thank goodness Julie Walters is returning.

Alexa Davies, of Harlots and Grantchester fame, will appear in the flashbacks as young Rosie.

If you couldn't get enough of Colin Firth's Harry the first time around, good news: he's coming back!

Hugh Skinner is playing young Harry, and we have no doubt the Fleabag actor will nail the part.

You'll see Stellan Skarsgard as Bill once again.

The part of young Bill will be played by Allied actor Josh Dylan.

Pierce Brosnan is set to return to Kalokairi to play Sam, Donna's true love.

Jeremy Irvine, who you've probably seen in projects like War Horse and Stonewall, will appear as young Sam.

Amanda Seyfried played bride-to-be Sophie Sheridan in the first film, so we're excited to see how married life is treating her!

The Preacher star will return to play Sophie's swoon-worthy husband, Sky.

Cher will be playing Donna's mother in the film.

Passengers actor Andy Garcia rounds out the cast as a new character named Fernando.
