A few months ago we learned that Colin Firth's casting in Matthew Vaughn's Kingsman: The Secret Service was contingent on him being able to effectively pull off the stunt moves in that insane church scene. This was one of the most jaw-dropping scenes in the film, and now we have a behind-the-scenes video that that shows us exactly how that brutal sequence was made. If you're a fan of this movie, this is a video that's worth checking out. It includes footage from the set of the film and the director and actors discussing it. Enjoy!
