To recreate the battle at Doo-Mil-Ryung, the scene required 15,000 bullets, 3,000 extras and 500 stunt experts. Instead of rifles being fired, fist fights were the main focus of the scene and all of the cast were specially trained. The shoot lasted 3 weeks with about 50 minor accidents a day on average, but the scene was finally wrapped without any major accidents.
