Moon was born in Tokyo, Japan. His father was Rev.

After graduation from Sogang University with a bachelor's degree in International Business, Moon worked as a salaryman for eight years.

In 1985, he began acting in theater, and became a key figure in the beginning of the renaissance of Daehangno stage plays in the mid-1980s, playing the leading role in such mega-hits as Chilsu and Mansu and Till the End of Time. Moon made his film debut in 1990 with Black Republic directed by Park Kwang-su.

During his acting career, Moon has won Best Actor award at the Blue Dragon Film Awards thrice, Baeksang Arts Awards twice, Chunsa Film Art Awards twice, and other accolades.

Moon started his political activities in 2009, becoming the Democratic United Party's temporary chairman in 2012. Since then, he has mostly made special appearances in movies.

In 2017, Moon and a group of South Korean artists filed complaints against two former presidents, Lee Myung-bak, Park Geun-hye, and other six senior officials, asking for a prosecution investigation over the allegation of an "artist blacklist."

Moon is a frequent collaborator of director Lee Chang-dong. He has starred in four of Lee's films, including critically acclaimed Burning (2018).
