One of the most notable features of the Assassin’s Creed games are the "leaps of faith"–spectacular dives from dizzyingly tall buildings. The movie adaptation arrives later this year, and a new behind-the-scenes video reveals that these amazing stunts are performed for real. Check it out below:

Assassin’s Creed is directed by Justin Kurzel, and stars Michael Fassbender, Marion Cotillard, Jeremy Irons, Brendan Gleeson, and Michael Kenneth Williams. The first trailer for the movie was released in May–watch it here.

In a recent interview with Collider, Fassbender spoke about the need to strike a balance between being faithful to the game and offering audiences something new. "We really want to respect the game and the elements to it, but we also wanted to come up with our own thing," he said. "And one thing I’ve sort of learned from doing the franchises like X-Men is that audiences, I think, want to be surprised and to see new elements of what they already know, and different takes on it.

"Like I said, we’re really respecting the very core elements of the game, but we wanted to bring something new to it as well, so that’s why we have these new central characters."

Assassin’s Creed hits theaters on December 21, 2016.
