Last week we shared with you the poster for the upcoming movie 71-Into the Fire starring Kwon Sang Woo and Big Bang's T.O.P. Now, a behind the scenes / making of video for the poster has been released. Wow, seems like a lot of work with a lot of set locations for just the posters! The war movie is based on a true account of the Battle of Pusan Perimeter in August 1950. It revolves around 71 South Korean student soldiers starring both Kwon Sang Woo and T.O.P. The students fight against hundreds of regular North Korean soldiers (led by Cha Seung Woo) during the deadly Korean War. In case you missed it, you can also check out the trailer here.
