Lee Sung-jae (Korean: 이성재) is a South Korean actor. Among his notable works include the films Art Museum by the Zoo (1998), Attack the Gas Station (1999), Kick the Moon (2001), and Public Enemy (2002).
He, in a short period, rose to become one of the more versatile and popular actors in Korean cinema. After working for a time on TV (his debut was in a MBC drama), he launched his film career with the romantic comedy Art Museum by the Zoo opposite superstar Shim Eun-ha. The success of this movie gave him considerable attention and led to him being offered many more roles.
After starring in Ghost in Love opposite Kim Hee-sun, Lee rose to prominence as the leader of a small group of thugs in one of the biggest box-office hits of the late 1990s, Kim Sang-jin's smash comedy Attack the Gas Station. Shortly thereafter he took a role in a very different kind of film, the accomplished black comedy Barking Dogs Never Bite, and his portrayal of a dog-hating lecturer who desperately wants to become a professor received good reviews.
