The film, to be directed by Josie Rourke, features Saoirse Ronan as Mary Stuart and Margot Robbie as Queen Elizabeth I along with Joe Alwyn, Martin Compston and Jack Lowden, reported Deadline.
Based on John Guy's 2004 biography 'The True Life of Mary Stuart', the movie follows Mary Stuart, who was forced to abdicate her throne after a controversial marriage and fled for the protection of her cousin, England's Queen Elizabeth I.
This is the first English-language film role for Dragus, who most recently co-starred in the 2016 Cannes selection "Graduation".
