Assassin's Creed Trailer.
I've only ever played the first two games and enjoyed them both. (This was before they turned it into an yearly franchise and I lost all interest in it.) The overall story, setting and characters should ideally translate well onto the big screen.
I was actually not interested in this initially, but then I saw the names associated with it: Fassbender, Cotillard, Irons, Gleeson etc. And it is directed by a Cannes Palme D'Or nominee, which is about as good as you can hope for a video game-turned movie.
I don't have much to say on the trailer itself besides the horrendous music choice. I am just interested in seeing how it'll turn out given the quality of the names involved. We'll see!
