I watched it because Hyun Bin was in it. It was a really great movie with lots of awesome action scenes and such a great plot and cast. You will enjoy it and give it a high rating if you watch it I just know it. They definitely picked the right people to play each character. I very much enjoyed the whole thing from start to finish. I've only watched a few Korean movies but this was really really good. If you like Hyun Bin's other movies where he plays awesome interesting characters then you will definitely enjoy your time watching Confidential Assignment.
