“Gangnam 1970” presented Lee with the opportunity to star in his first major film role, which was well-received by audiences and critics. The actor has admitted that the filming process was challenging, particularly during action sequences which were filmed in muddy conditions.

The bulk of his previous acting roles have been within the genres of romantic comedies and melodrama. In 2011, he starred as Lee Yoon Sung in the cinematic drama, “City Hunter.” He followed “City Hunter” with the supernatural period drama, “Faith.” “Faith” also incorporated sequences of stage combat but not to the same degree of intensity as “City Hunter” or Gangnam 1970.”

“Gangnam 1970” is in the midst of its Chinese release, with the film receiving additional scenes which were cut from the Korean edition of the film.
