I'm a huge Assassin's Creed fan, and as much as I trust Ubisoft (creators of the game) to make the film, I feel like Michael Fassbender doesn't quite fit the tone of the AC franchise. If they're hiring a big actor like him, then odds are he's playing as either Desmond, Altair, or even both (assuming the movies will be done in the same order as the games). We'll just have to see what Ubisoft will do I trust they'll make the right decision.
No I do not want it to become a film so soon. Can't they wait a while? Or if they feel so desperate make a completely new Assassin and keep Desmond out of it? Maybe a film based on Subject 16 up until his suicide? That would be interesting. This Fassbender.....
