French actress Marion Cotillard has signed on to the upcoming Assassin’s Creed movie.

According to Deadline, Ubisoft and production company The New Regency have yet to reveal her role in the movie.

Cotillard and her co-star Michael Fassbender acted together in an upcoming adaptation of Macbeth, which the director of the Assassin’s Creed movie, Justin Kurzel, also directed.

Cotillard, who you might recognize from The Dark Knight Rises or Inception, also won an Oscar for her role as singer Édith Piaf in 2007’s biopic La vie en Rose. Fassbender was also nominated for his role in 2013’s 12 Years a Slave.

Last week, we learned that the Assassin’s Creed movie officially entered production and should start shooting soon. The movie, produced by New Regency and 20th Century Fox, will hit theaters on December 21, 2016. That’s one week after the first Star Wars spinoff movie hits cinemas.

Ubisoft is working on five other movies based on its games at the moment: Far Cry, Rabbids, Watch Dogs, Splinter Cell, and Ghost Recon franchises. In all instances, Ubisoft will retain creative control through its Ubisoft Motion Pictures group.
