Lee was discovered by designer Ha Yong-soo while he was working at a café inApgujeong-dong (located inthe Gangnam District), then worked as a fashion model for a number of years. Upon making his acting debut with the 1993TV dramaDinosaur Teacher, Lee became a star practically overnight, and was almost always cast in lead roles thereafter. A year later, he received favorable reviews for his first big screen role inBae Chang-ho'sThe Young Man, but it was the 1994 hit campus dramaFeelings that made him a household name.[13]
In 1995, what was supposed to be a small supporting role as the heroine's silent, devoted bodyguard in ratings behemothSandglass turned Lee into a national heartthrob, such that his screen time was increased throughout the series' run.[14][failed verification]

In 1997, following his return from the military, his career went into a slight decline. It was then he decided to return to acting school by enrolling intoDongguk University's Department of Theatre & Film.[15]

The film was one of Lee's biggest hits ever, topping three million admissions at the local box office.[16] Nonetheless, he remained out of the limelight for the next couple years. Finally at the end of 2005 he returned inTyphoon, a big-budget action blockbuster byKwak Kyung-taek, the director ofFriend.[19]

With the period action comedyThe Accidental Gangster and the Mistaken Courtesan, Lee said he wanted to try his hand at playing a different kind of role, a comical loose cannon type of character.[22] Though it was not successful at the box office, he still considers it one of his most memorable films.[23]
El Fin del Mundo ("The End of the World") is a 13-minutesplit screen film made by visual artists Moon Kyung-won and Jeon Joon-ho, which depicts the destructive environmental changes the world faces in the future and the subsequent end of art and birth of new art based on dialogue between two artists in different times and space, played by Lee andIm Soo-jung.[32] The film was screened atdOCUMENTA in 2012, considered the world's most prestigious and innovative contemporary art platform.[33][34][35] A longtime art collector and honorary ambassador for theNational Museum of Contemporary Art in 2011–2012, Lee also narrated the 2013TV documentaryContemporary Art, Bury the Boundary which highlighted homegrown Korean artists.[36]

Despite these criticisms, Lee has been praised for shifting from a more lighthearted character to a darker one in the second season.
