Christopher Plummer has won his first Oscar, given for Actor in a Supporting Role for "Beginners," which marked his second nomination.
Plummer, 82, is now the oldest Oscar winner. He beat nominees Kenneth Branagh of "My Week With Marilyn," Nick Nolte of "Warrior," Max von Sydow of "Extremely Loud & Incredibly Close" and Jonah Hill of "Moneyball." The winners of the 2012 Academy Awards were named at a Los Angeles ceremony on Sunday, February 26.
"You're only two years older than me, darling," he said to his statuette. "Where have you been all of my life?"
"When I first emerged from my mother's womb, I was already rehearsing my Academt thank you speech, but it was so long ago, mercifully for you, I've forgotten it."
He did not, of course. The actor thanked the people involved in making "Beginners," his fellow nominees as well as his daughter, Amanda, who he said "always makes me proud."
"And lastly, my long-suffering wife Elaine, who deserves the Nobel Peace Prize for coming to my resuce every day of my life. Thank you so much." (Check out a video of his speech.)
The previous star to hold the record for being the oldest person to win an Oscar was George Burns. He was 80 when he earned his Academy Award for his performance in the 1975 film "The Sunshine Boys." He died in 1996, less than two months after his 100th birthday.
Jessica Tandy was also 80 when she won the Oscar for Best Actress for her role in the 1989 film "Driving Miss Daisy." She died at age 85 in 1994.
Plummer was previously nominated for an Oscar for Best Performance by an Actor in a Supporting Role for the 2009 film "The Last Station."
"Beginners" is based on director and screenwriter Mike Mills' ("Thumbsucker") late father, who came out as a gay man at age 75.
Plummer has won several awards for the role including a BAFTA Film Award, a Screen Actors Guild Award and a Golden Globe.
When they were preparing for the film, Mike Mills sent Plummer and McGregor to Barneys to buy a scarf as part of a father-son bonding exercise.
"Mike said, okay, I want you to go to Barneys and here's $200, I want you to buy Christopher a scarf and Christopher, now you're gay and you want to look fabulous in your scarf," McGregor said in an interview provided by Focus Features. "He was sort of dismissive, thinking 'What is this, going to Barneys to buy a scarf,' but then he went 'What are those?' and he looked at my jeans and I said 'They're just black jeans, Christopher' and he said 'They're very tight' and I said, 'Well, they're skinny jeans, you would call them skinny jeans.' So when we went to Barneys, he had his mind set on skinny jeans."
Plummer's career spans 64 years and he has appeared in roughly 103 films. He is perhaps best known for his roles as Captain Von Trapp in "The Sound of Music," Dr. Rosen in "A Beautiful Mind" and Doctor Parnassus in "The Imaginarium of Doctor Parnassus."
Plummer most recently portrayed Henrik Vanger in "The Girl with the Dragon Tattoo," a U.S. film adaptation of the books by Stieg Larsson. The movie won an Oscar for film editing earlier on Sunday, and its main star, Rooney Mara, is nominated for Actress in a Leading Role.
