In Gojijeon Ko Soo will acts as Su Hyuk , a timid guy who later becomes a real man. Gojijeon is directed by a blockbuster director : Jang Hoon who made "Secret Reunion" in 2010.
Gojijeon is a war movie about Korean war, which started from 1950 - 1953. We can imagine how hard our Ko Soo filming Gojijeon. It's winter and he must stay in the mountain. Wow...that's not a joke, luckily the filming will end in mid February.
