Whether she's visiting 19th century Russia or 2002 Sacramento, Saoirse Ronan loves to time travel. Up next, she'll visit the 1500s in Mary Queen of Scots.

The film, which is directed by Josie Rourke, sees Ronan face off against Margot Robbie in a rivalry that escalates into a war.

Based on the trailer, it looks like a high-budget period drama that will please movie-goers and future history classrooms alike.
