Rumors about Mamma Mia! 3 have also been fueled by the cast members’ comments expressing their enthusiasm about reprising their respective roles.

In an August 2024 interview with The Hollywood Reporter, Baranski confirmed that she met Craymer, who was planning Mamma Mia! 3, in London.

“She gave me the narrative plotline of how it’s going to happen. That’s all I can say! But, it’s not like, ‘Oh, I wish it could happen!'” she said. “Judy Craymer makes things happen. She made number two happen, and it was a phenomenal hit. I wouldn’t put it past Judy Craymer to get everybody back together.”

Meanwhile, Seyfried told Radio Times she was also up for a Mamma Mia! sequel.

As for Brosnan, he revealed he would love to be part of the third installment, especially if Streep is on board, despite her character’s death featured in the first and second movies.

“Having Meryl’s character die kind of gave us so many good storylines,” Seyfried told Collider in June 2020. “It was kind of a genius idea because you’re like, ‘No, we don’t want to lose her.’ But at the same time, look at what you can do, you can go back.”

But good news for Brosnan, Seyfried and the rest of the cast, as the Oscar-winning actress has not ruled out playing her part in Mamma Mia! again.

Streep told Vogue, “I told Judy [Craymer] if she could figure out a way to reincarnate Donna, I’m into that. Or it could be like in one of those soap operas where Donna comes back and reveals it was really her twin sister that died.”
