See Margot Robbie Transformed As Queen Elizabeth I For New Movie 

The Australian actress, 27, made fans do a double-take when she debuted a bold new look while filming in London this week for her upcoming movie 

. The film will chronicle the Scottish queen’s unsuccessful attempt to overthrow Robbie’s Queen Elizabeth I for the English crown and her infamous imprisonment and eventual execution.

Robbie’s startling transformation — from her normally glossy blonde locks and flawless skin to a partially shaved head with fiery red hair and a blotchy complexion —  are all part of getting into character for her role. (Queen Elizabeth I reportedly had a pock-marked face due to smallpox, which she covered with dangerous white makeup that did further damage to her skin.)

Robbie was also spotted donning traditional Tudor wear for the part of the Virgin Queen, which included a black ensemble consisting of a corset, jacket and wide buckled skirt.

Robbie will play opposite Irish actress Saoirse Ronan, who will star in the title role of Mary Queen of Scots. British actor Joe Alwyn, 26— who is also Taylor Swift‘s new beau— will be playing the role of Dudley, Queen Elizabeth I’s counselor and lover.
