I haven’t heard much about this but the sneak peek looks pretty good. The movie is about a 13th century group of Knights Templar who defend Rochester Castle against the tyrannical King John. Sounds like it could be an epic movie.
Cinematical.com gives us the 411:
This footage is from the first two weeks of filming, so it’s pretty rough, the soundtrack is temporary, and it was filmed prior to pre-Paul Giamatti being cast as King John. But there’s still an impressive level of carnage on display, and everything remotely sharp or heavy is being wielded in defense of Rochester Castle. There’s no slick choreography, it’s just white-knuckle, balls-to-the wall medieval warfare. They still found room for a few explosions, though. Remember, King John used pig fat to melt the walls, so there was definitely a lot of falling stone during this siege.
