Studied at American Conservatory Theater in San Francisco, California, USA. For Mulan (1998), he had another person do his singing voice because his own voice was too good. In his audition for the film Sixteen Candles (1984), he went through the entire process pretending he did not speak any English, imitating a Korean friend. After he was finished, he eloquently thanked the casting director in perfect English. He was soon cast.
