It’s a good day to be a Saoirse Ronan fan, which is all of us, really – I mean, who doesn’t enjoy the always delightful Irish actress? Following her Vogue cover story this morning, which includes a fun video where she makes tea and screams about how much she hates dessert, Focus Features debuted the the first posters of Ronan and Margot Robbie in one of the fall’s most exciting biopics.

The Lady Bird star will play the Scottish monarch in Mary Queen of Scots alongside Robbie, who portrays Queen Elizabeth I. The historical drama, which comes from British theater director Josie Rourke in her big screen directorial debut, is set in the 16th century and follows Ronan’s Mary Stuart, who led quite a wild and controversial life. After being married and becoming the Queen of France at 16, she was widowed two years later, then returned to Scotland to reclaim the throne, and married her cousin who was then murdered. Before the first trailer arrives tomorrow, get a look at Ronan and Robbie’s queens in a set of stunning posters.

And here’s Robbie with fire-red hair:

Here’s the official synopsis:

Mary Queen of Scots 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.

The film is written by House of Cards‘ Beau Willimon and adapted from John Guy’s biography Queen of Scots: The True Life of Mary Stuart. The cast also includes Jack Lowden, Joe Alwyn, Gemma Chan, David Tennent, and Guy Pearce. Prepare for Ronan and Robbie to duke it out for the crown, and maybe be front-and-center of the awards race, once Mary Queen of Scots arrives on December 7.
