Margot Robbie looks unrecognisable in the latest leaked photo from the sets of her movie, Mary, Queen of Scots.

In the on-set image taken in London, the Suicide Squad actress seems to have traded in her blonde locks for a fiery red mane and her usually flawless complexion for a blemished skin, in order to bring the role of Queen Elizabeth I to life.

The 27-year-old Australian actress also donned a black corset and traditional Tudor garb, embodying the Virgin Queen, whose reign spanned much of the 16th century.

Fans took to social media to react to The Wolf Of Wall Street star's startling transformation. A user commented on Twitter, "Wow. I would not have recognized her." Another confused user asked, "That's...thats Margot Robbie?!" while yet another comment read, "wow. She's unrecognizable. Looking forward to this!"

However, some people were clearly unimpressed with her looks. "She looks horrible!", "But she looks horrendous," "These pics of Margot Robbie dressed as Elizabeth I are scaring me," and "Margot Robbie looks so ugly as Queen Elizabeth," were some negative tweets on her transformation.

Robbie, who rose to fame playing Leonardo DiCaprio's wife in Academy Award-winning film The Wolf Of Wall Street, will star alongside Saoirse Ronan who is set to play Mary Stuart.

Actors David Tennant and Guy Pearce will also appear in the Josie Rourke-directed movie, which will chart the life of Queen Elizabeth and showcase the rivalry between the two monarchs, the Scottish queen's efforts to take over Elizabeth's throne and her subsequent imprisonment and execution.

Mary, Queen of Scots is scheduled to be released in late 2018 by Focus Features and Universal Pictures.
