Song Jae Rim Interview:

"The action scene with Kim Hyun Joong was one of the best executed. He is my best opponent. Kim Hyun Joong and I suit best as rivals. Our style is to hit in reality when we were asked to. So when we were hitting each other, I felt comfortable. I also did one of the most difficult scene with Kim Hyun Joong. We did it perfectly despite we shot it during cold day.
