Career
Kim Kang-woo majored in Theater and at Chung-Ang University, and made his acting debut in Kim Ki-duk"s 2002 film The Coast Guard while still a senior, later commenting that the role of a soldier was the only one he could get without any prior experience. Subsequent roles in the drama series Breathless and Three Leafed Clover earned Kim the nickname "Mr. Right" as he became known for his portrayal of honest and diligent characters.
His first leading film role was in Jeong Jae-eun"s 2005 sophomore feature The Aggressives, for which he and co-star Chun Jung-myung were the co-recipients of the "Best New Actor" award at the 6th Busan Critics Awards.
In 2007, Kim starred in Park Heung-sik"s The Railroad, which told the story of two strangers who reveal their inner pain to each other when they are stranded at the last railway station before the Korean Demilitarized Zone. He also admitted to being anxious because of the increased expectations people would have over his future performances.
Kim found commercial success with his next film, Le Grand Chef, which despite opening during a slow season sold more than three million tickets to become the fourth biggest selling South Korean film of 2007. To prepare for his role, Kim attended cooking classes for one and a half months, and for one crucial scene in particular he visited a slaughterhouse, receiving a big shock as he knew nothing about the slaughtering process.
In addition, he was required to film a number of scenes with a cow, and spent some ten days acquainting himself with it—grooming it, feeding it and taking it for walks—remarking that it was "like working with a very sensitive actress".
In August 2014, Kim left his previous management agency Namoo Actors, and signed with C-JeS Entertainment.
