Captain America: The First Avenger star Hayley Atwell has revealed that she has a role in Kenneth Branagh's Cinderella.

Atwell broke the news on her Twitter account saying she would be joining the cast.

Speaking to BBC News she said, "When Cinderella is 5 years old she loses her mum, and she's a good mum – that's all I can really say, that it's her biological mum."

She also spoke about how she looks forward to working with Branagh, "I'm really looking forward to working with [Branagh] – he knows how your mind works, so it's wonderful. He's very thorough, like a theatre director."

Atwell joins a star-studded cast with Cate Blanchett, Helena Bonham Carter, Lily James and Richard Madden already cast.

Cinderella is due for release in 2015.
