In 2009, Lee, Cho Jae-hyun, Choi Soo-jong, Sol Kyung-gu, Kim Hye-soo, Ahn Sung-ki and Park Joong-hoon each taught a master class in acting at the Im Kwon-taek Film and Art College of Dongseo University. All of them then waived their lecturing fees and donated the entire amount to scholarships for young actors. Lee said he willingly accepted the request to teach because he wanted to contribute to training talented film experts for the future of the Korean film industry, and that he was happy to donate his fee to that cause.
