Ubisoft has always promised that the upcoming Assassin's Creed movie would tie into the canon of the games. That being said, no one outside of the production team knew exactly how this would work — but thanks to actor Michael K. Williams, fans now know at least one of the connections between the film and the game.

In an interview with Screenrant, Williams shared some details about his role in the upcoming film:

"My character, he's in this prison, whatever this place we call it. His name is Moussa. He is going to ... When he becomes an Assassin, he's going to channel his ancestor, which is a voodoo poisoner who has been dead for about 200 years. His name is Baptiste."

That might not sound like much to non-fans of the franchise, but hardcore Assassin's Creed fans will recognize Baptiste as a character from Assassin's Creed III: Liberation. More specifically, he was the leader of a voodoo cult, and was eventually assassinated by the game's protagonist. So, how exactly does Williams' character actually fit into the film?

"... Moussa is what we call the trickster. His whole thing when Cal comes into the prison, he sees him as the missing link to the puzzle and immediately realizes that we need to bring him into the fold ... and to let him know that we all need to get out of here."

From what Williams has said, it's easy to assume that Moussa will act as something of a guide — and not just for Michael Fassbender's Callum Lynch, but for the audience as well. After all, there are a lot of people who have never played the games before — given just how convoluted the world of Assassin's Creed can get, having someone to help explain the basics could come in very handy. Even more interesting is that Baptiste was an antagonist — could Williams' role in the film end up playing out in a similar fashion, or will he and Fassbender become fast friends?

All in all, the Assassin's Creed movie looks to be on the right track — while the music in the first trailer wasn't exactly ideal, the look and feel was on-point. It's still too early to tell, but who knows — maybe Assassin's Creed will prove that video games can make the jump to the big screen.

Assassin's Creed is due out in theaters this December.
