WESTON, CONNECTICUT -- Christopher Plummer, the acclaimed Canadian actor perhaps best known for his role in "The Sound of Music," has died. He was 91. The Oscar winner died at his home in Connecticut with Elaine Taylor, his wife and true best friend for 53 years, by his side, his manager confirmed to ABC News. "Chris was an extraordinary man who deeply loved and respected his profession with great old fashion manners, self deprecating humor and the music of words. He was a National Treasure who deeply relished his Canadian roots.
