Our Saoirse Ronan certainly knows how to morph into absolutely any role going, and she has proved that once more with the first image released of her as Mary Queen of Scots.

Filming has begun on the Working Titles flick which follows the life of Mary Queen of Scots as set out in 'My Heart Is My Own: The life of Mary Queen of Scots', a biography by John Guy.

Saoirse takes the lead role as Mary while Margot Robbie will star alongside her as Elizabeth I (yes, we're also struggling to envision the latter but she could pull it off).

Here's the pic of Saoirse:

The movie has actually been trying to get off the ground for years with Scarlett Johansson originally set to play the lead back in 2006. The current project is directed by Josie Rourke while the screenplay was written by House of Cards' Beau Willimon. It's produced by Working Title co-chairs Tim Bevan, Eric Fellner and Debra Hayward who all received best picture Academy Award nominations for Les Misérables.

If you need brushing up on your history, the film tells the story of how Mary Stuart's attempt to overthrow her cousin Elizabeth I, Queen of England, finds her condemned to years of imprisonment before facing execution.

Other cast members include LA Confidential actor Guy Pearce, Doctor Who actor David Tennant, Downton Abbey's Brendan Coyle and Dunkirk actor Jack Lowden.

It's set to be released in 2018.
