We have known an Assassin's Creed movie was coming, and when Michael Fassbender was announced to play the lead assassin, we thought that the film had potential. Now we get the first trailer, and nothing has changed our first impression.

The trailer, which was revealed on Jimmy Kimmel Live last night, shows Fassbender as Callum Lynch, a career criminal executed, then saved by Abstergo Industries. Fans will recognize Abstergo and the Animus, as well as the nefarious Templars, but the setting and hero are new. Once inside the Animus, Fassbender becomes assassin Aguilar de Nehra from 15th century Spain during the Inquisition. 

We also get a glimpse of Ariane Labed as fellow assassin Maria, and Marion Cotillard as Sophia Rikken, daughter of Abstergo CEO Alan Rikkin, as she talks Lynch through the Animus and what is expected of him. And as with the games, the trailer offers plenty of tumbles, acrobatics and leaps of faith.

The film is being directed by Justin Kurzel, with the script was written by Michael Lesslie. It is set to be released on December 21 of this year. You can already get tickets for the film - and maybe a crossbow too.
