He starred on Broadway in M Butterfly, and in the TV series Law & Order: SVU and HBO's Oz. He's the author of the new book Following Foo (the electronic adventures of the Chestnut Man). It's about the premature birth of his twin sons in August 2000. The twins suffered a rare medical disorder. One of them died shortly after birth, and the other twin, Jackson Foo, was in neonatal intensive care for three months. At the time Wong began an e-mail correspondence with family and friends on Jackson Foo's progress.
