American character actor, playwright, and film historian. A native (and devoted) Texan, Addington attended Southern Methodist University as a theatre student. He lived his entire life in Dallas, acting in scores of theatrical productions and making appearances in numerous locally- filmed movies and television programs. In addition to acting, he was equally busy as a respected film historian and teacher. He returned to his alma mater, Southern Methodist University, to teach film courses including a popular course on Alfred Hitchcock, on whom he was an expert and with whom he became a friend in Hitchcock's later years. Addington was also active in union work, serving on the local boards of both the Screen Actors Guild and AFTRA. A large man with both a genial personality and a wicked sense of humor, Addington died at 44 of a heart attack while napping at home.
