William Patrick Muldoon III (September 27, 1968 — April 19, 2026) was an American actor of Irish and Croatian ancestry. His parents' artistic backgrounds, in painting, writing, and music, induced the same appetites in their son, as well as athletics. He played college football for the U.S.C. Trojans and has two Rose Bowl rings.
