Which actor played Callum Lynch and Aguilar de Nerha in the 2016 Assassin's Creed film?

Michael Fassbender played Callum Lynch and Aguilar de Nerha in the 2016 Assassin's Creed film.

Callum Lynch is the film's modern-day protagonist, while Aguilar de Nerha is his Spanish Assassin ancestor. Through the Animus, Callum experiences Aguilar's memories during the Spanish Inquisition. Fassbender therefore plays two connected roles: the present-day descendant and the historical ancestor whose memories drive the central plot.

The film was directed by Justin Kurzel and released in December 2016. Its cast also includes Marion Cotillard, Jeremy Irons, Brendan Gleeson, and Michael K. Williams. The story uses the series' established ideas about genetic memory, the Animus, Assassins, and Templars while introducing a new protagonist rather than adapting one game's campaign directly.

Fassbender is sometimes remembered only as Callum Lynch, but his historical role is equally important. Aguilar's sequences provide the film's action in fifteenth-century Spain, while Callum's modern storyline connects those memories to the ongoing conflict.
