'Assassin's Creed' First Look: Here's Michael Fassbender as Brand New Character (Exclusive)

Meet Michael Fassbender as Callum Lynch in Assassin’s Creed.

Based on the massively popular — and prolific — video-game series of the same name, the movie version is set to open in theaters Dec. 21, 2016.

Before hardcore Assassin’s Creed gamers start scratching their heads (and filling up the comments) about how exactly Callum Lynch fits into the game world, we can tell you that Fassbender’s character was created specifically for the film. (The movie isn’t retelling any of the existing games, but rather introducing new characters into the same world.)

Lynch discovers he is a descendant of the secret Assassins society through unlocked genetic memories that allow him to relive the adventures of his ancestor, Aguilar, in 15th Century Spain. After gaining incredible knowledge and skills he’s poised to take on the oppressive Knights Templar in the present day.

Also starring Marion Cotillard (The Dark Knight Rises), Michael Kenneth Williams (12 Years a Slave), and Ariane Labed (Before Midnight), cameras start rolling for Assassin’s Creed on Monday. Filming is set to happen in Malta, London, and Spain.
