Mary Queen of Scots is an upcoming British-American historical drama film directed by Josie Rourke and written by Beau Willimon. It is based on John Guy’s biography My Heart Is My Own: The Life of Mary Queen of Scots. The film stars Saoirse Ronan as the titular character with Margot Robbie, David Tennant, Jack Lowden, Martin Compston, Joe Alwyn, Brendan Coyle and Guy Pearce. The film is scheduled to be released in the United States on 7 December 2018, and in the United Kingdom on 18 January 2019.
All the writing against Mary had an effect, giving a popular impetus to the parliamentary petition that urged the Queen to execute the Queen. After that execution in February, 1587, Elizabeth claimed she was tricked into signing the death warrant.
A year after the execution, Philip V of Spain sent the Armada to bring Catholicism back to England. That didn’t go as planned. Elizabeth ruled for nearly two more decades. Upon her death in 1603, the crowns of England and Scotland were merged in union and the throne went to James VI of Scotland—Mary’s son, whom she hadn’t seen since he was thirteen months old.
