The debut trailer for the upcoming historical piece Mary Queen Of Scots has graced the internet. The period film, which stars Saoirse Ronan and Margot Robbie, will be released in cinemas later this year.

The film explores the turbulent life of the charismatic Mary Stuart (Ronan). Queen of France at 16 and widowed at 18, Mary defies pressure to remarry. Instead, she returns to her native Scotland to reclaim her rightful throne. But Scotland and England fall under the rule of the compelling Elizabeth I (Robbie). Each young Queen beholds her “sister” in fear and fascination. Rivals in power and in love, and female regents in a masculine world, the two must decide how to play the game of marriage versus independence. Determined to rule as much more than a figurehead, Mary asserts her claim to the English throne, threatening Elizabeth’s sovereignty. Betrayal, rebellion, and conspiracies within each court imperil both thrones – and change the course of history.

Mary Queen Of Scots is set to arrive in U.S. cinemas on December 7th, but won’t hot U.K. screens until 18th January 2019. Check out the first trailer below.
