He already has a couple of Tonys, a couple of Emmys, and several other awards. Now Ontario-born actor Christopher Plummer can add one more to his collection: An Oscar.

Sunday, 82-year-old Plummer became the oldest person to win an Academy Award for acting. He received the Best Supporting Actor Award for his performance in "Beginners." Here's the film's trailer:

In January, 2011, Steve Paikin went to the Elgin Theatre in Toronto to see Plummer perform the title role in "Barrymore", for which he won his second Tony Award on Broadway in New York. (Plummer's first was for a musical adaptation of "Cyrano de Bergerac.")

After the performance, Steve wrote a blog post about the experience. Here's what he had to say:

The Greatest Actor in the World

By Steve Paikin, January 30, 2011

I can't ever recall seeing an audience rise to its feet as one as quickly as it did last night for Christopher Plummer.

Plummer is reprising his Tony-award winning role in "Barrymore," now playing at Toronto's Elgin Theatre.

Throughout the play, I kept wondering, who's a better actor, anywhere in the world, than this man?

Must confess, I was stuck for an answer. I tweeted that question last night as well, and so far, other seem equally stumped to name a better actor than Christopher Plummer.

Here are a couple of replies:

* thanks for asking, we overheard people all over St. George station continuing the conversation, including us. :)

* he's brilliant. And yet an almost completely unsympathetic in every interview. Insufferable blowhard, but acting genius.

"Barrymore" chronicles the last month of legendary actor John Barrymore's life – a life that was eerily similar to Plummer's before the Canadian cleaned up his act many years ago.

Plummer is simply brilliant at moving from hilarity, to pathos, and back. To see this play is to see someone at the absolute top of his game at work.
