This study is on the activities of Chosun Film Studio's actors who played a crucial role in the actors' movement of Korean Liberation Period. When making of feature films had stopped right after the liberation, film actors started on movement. They were main members of Chosun Film Alliance, which became weaker because of the confrontations between the left and the right as well as the suppression of the US military government. Raising a hare in regard to post liberation issues such as the problem of pro-Japanese, they were involved in conducting campaigns in the name of Chosun Film Actors' Company. This movement ended when the 2nd US-USSR Joint Commission had ended without results and the suppression to the left had escalated. Important people in the film industry such as Moon Ye Bong defected to North Korea and worked there. Even though the leftist movement ended in failure, Lee Sung Man government of South Korea started to track down left wing opponents. All who had ever been participated in the leftist activities should turn themselves in, and reform their ideology joining the Federation Protecting and Guiding the Public. Actors and film makers who stayed behind in the South also joined the Federation. During the Korean War, however, the members of the Federation and actors who had collaborated with the North Korean occupying force were suppressed ruthlessly. As a result, many of them such as Dok En-Gi, Nam Seung-Min, Choi Un-Bong chose to defect to North Korea and appeared in propaganda films such as <Young Partisans 소년 빨치산>during the war. Others who had survived the suppression stayed in South Korean camp, for instance, Kim Il-Hae joined the South Korean military art company. In this period from the liberation to the war, the famous actors were not able to work in an independent way, but rather be forced by the nation and the regime They suffered from losing their independence under the name of the nation.
