What is the name of the 2016 Assassin's Creed film's main character?

The main character of the 2016 Assassin's Creed film is Callum Lynch.

Callum Lynch is a modern-day man who is recruited by the Abstergo Foundation and connected to the Animus. Through the machine, he relives the memories of his Spanish ancestor Aguilar de Nerha, an Assassin active during the Spanish Inquisition. The film uses this ancestor-memory structure to adapt the franchise's central science-fiction premise for cinema.

Michael Fassbender plays Callum Lynch, which is why the actor's name is sometimes incorrectly supplied as the character's answer. Desmond Miles is the modern protagonist of the original game-era storyline, not the film. Aguilar is crucial to the film's historical sections, but he is Callum's ancestor rather than the movie's principal modern-day character. The film premiered in December 2016.
