The Emmy winner told on Tuesday: ‘I was in London with Judy Craymer at our favorite watering hole, she is planning Mamma Mia 3. She gave me the narrative plotline of how it’s going to happen’ (pictured Sunday)

Craymer also expressed her enthusiasm for the project, stating, “There is a story there, and I do think Meryl [Streep] should come back — and if the script is right, she would, I think, because she really loved playing Donna. I don’t want to over-egg it, but I know there’s a trilogy there.”

The Mamma Mia franchise has been a massive success, with the first film grossing $694.6 million at the global box office and the sequel earning $402.3 million. A touring production of the musical is currently running in the States, and ABBA’s virtual concert residency is running at ABBA Arena in London.

Baranski noted, “Mamma Mia made so many millions of people around the world happy. Is it a little dumb, a little campy? That’s part of its charm. When I’m in Europe, I can’t tell you how many little girls want to be photographed with Tanya. It troubles me a little, that Tanya’s their favorite character [laughs]. But, hey, we’re always attracted to that kind of snappy, sexy lady.”

In addition to her work on Mamma Mia, Baranski has been busy reprising her role as old-money socialite Agnes van Rhijn in the third season of HBO period drama The Gilded Age. The show has received several Emmy nominations, including outstanding drama series, costumes, and production design.

On July 17, Baranski scored a nomination for outstanding supporting actress in a drama series at the Emmy Awards, which air September 15 on ABC.

Christine told Deadline of her character: ‘She’s suddenly not the head of the household, which you can tell from the way season two ended, that this proud haughty lady who was used to being number one is suddenly not that. So that fall from grace and that fall from power, that’s always such a delicious thing to play, and the fall of a King is just as exciting as the rise. So it makes for a lot of humor, I think, her having to eat humble pie’

Baranski’s personal life has also been busy, as she recently wrapped her role as Victoria alongside Nicole Kidman in the Swiss Alps-set second season of David E. Kelley’s drama Nine Perfect Strangers, which will eventually stream on Hulu.

The grandmother-of-three has two daughters, Isabel, 39, and Lily, 36, from her 30-year marriage to husband Matthew Cowles, who passed away in 2014.
