The Knick star is alleged to have beaten out competition from Belle actress Gugu Mbatha-Raw, Vampire Academy's Lucy Fry and Dutch newcomer Gaite Jansen to get the casting call from Peaky Blinders director Otto Bathurst.

If she signs on, she will star opposite Kingsman: The Secret Service star Taron Egerton, who has already been cast as a young Robin Hood, according to

Leonardo DiCaprio and his Appian Way partner Jennifer Davisson will serve as co-producers on the project, which is expected to go into production next summer (16).

It's one of four Robin Hood pictures in the works - Disney bosses are developing Nottingham & Hood, while Warner Bros. executives have hired Gangster Squad writer Will Beall to pen their take on the folk tale, and Sony Pictures chiefs are working with Jerry Bruckheimer on another film.

Cate Blanchett portrayed Maid Marian in Ridley Scott's 2010 release Robin Hood, while Audrey Hepburn, Mary Elizabeth Mastrantonio and Olivia de Havilland have all also played Robin Hood's love interest in previous films.
