Son born in 1996.

He attended Freedom High School in Bethlehem, Pennsylvania, the same high school as Dwayne Johnson.

He holds an M.F.A. from the Graduate Acting program at New York University.

While getting small parts in plays and writing and performing in an improv comedy group, he seriously considered a career in investment banking.

Arrested in Honolulu on October 25, 2007 for allegedly driving drunk.

He was included on People Magazine`s list of the sexiest men alive in 2005. Matthew McConaughey topped the list.

His acting heroes are Paul Scofield, Gene Hackman, Robert De Niro, Sidney Poitier, Gene Kelly, Denzel Washington, Robert Duvall and, his favorite, Jonathan Pryce.

Grew up in Easton, Pennsylvania.

Due to his childhood in America, he knew very little Korean before he did `Lost` (2004). He has said that his co-star on that show Yunjin Kim, who is fluent in both English and Korean, has been invaluable in coaching him on his Korean, which has apparently improved. Ironically, to the audience`s knowledge, Daniel`s character knows nothing but Korean.

He has said that playing `Jin` on `Lost` (2004) is a relief to him because he`s finally playing someone of his own heritage (Korean), having been cast as characters of almost every other Asian heritage but his own.
