Christopher Plummer wins supporting actor Oscar for ’Beginners’

Los Angeles: Christopher Plummer won the Oscar for best supporting actor on Sunday for "Beginners," in which he plays an elderly man who comes out of the closet and embraces his gay identity. 

Plummer, 82, a veteran screen and stage star best known as Captain von Trapp in "The Sound of Music," became the oldest person to receive an Oscar in the history of the Academy Awards. 

The Canadian actor, who had only one previous Oscar nomination, swept the Hollywood awards season for his performance in "Beginners" which was based on the true story of director Mike Mills' experience with his own father.
