The 67-year-old actress starred as Rosie Mulligan in the hit 2008 movie adaptation of the hit musical and reprises her role in the highly anticipated sequel.

Walters insists she and her castmates are finding the musical elements required for the sequel simpler to master this time round and she's having a lot of fun.

Speaking at the world premiere of 'Paddington 2' at the BFI Southbank in London on Sunday (05.11.17), Walters told BANG Showbiz: "I'm still doing 'Mamma Mia 2', I'm just about to finish that, it has been fantastic fun. I love the singing and the dancing. It's getting easier now. Pierce [Brosnan] looks fabulous. Everybody looks fabulous."

Walters will star alongside Meryl Streep, 68, Amanda Seyfried, 31, Colin Firth, 57, Stellan Skarsgard, 66, Brosnan, 64, and Dominic Cooper, 39, who are all reprising their roles from the first movie.

'The Best Exotic Marigold Hotel' scribe Ol Parker has written and directed the Universal Studios film, while Playtone Pictures, which produced the first instalment, has jumped back on board.

'Mamma Mia!' focused on a bride-to-be Sophie Sheridan (Seyfried) trying to find her real father so that he can walk her down the aisle at her wedding to Sky (Cooper).

But she gets a shock when she discovers that there are three potential men that could be her biological dad.

It's not yet known how bosses plan to push the story on but it's thought they may decide to follow the angle of how Sophie's mother Donna Sheridan (Streep) met the three men; Sam Carmichael (Brosnan), Harry Bright (Firth) and Bill Anderson (Skarsgard) in the years before the original story takes place.

Walters is currently reprising her role as Mrs. Bird in 'Paddington 2' and said there were no reservations for her to return to the popular children's flick.

She said: "There were no reservations returning. Because it was a massive success people loved it, the critics loved it and the public loved it. So we wouldn't not want to be involved so definitely it was fab."

Pierce Brosnan is an Irish actor, film producer, and activist.
