He was mostly known for TV roles, being a Yale classmate of Dick Cavett’s, and for playing the leading man in Beneath the Planet of the Apes, but he also acted opposite Charlie’s Angel’s Jaclyn Smith in Jacqueline Bouvier Kennedy (1981). “His preppie good looks enabled James Franciscus to successfully portray JFK,” according to a New York Times bio. He also played President James Cassidy in the roman a clef The Greek Tycoon.
