Gary Oldman has described his first ever Oscar nomination as "extremely humbling".
The British actor is up for the Academy Award for best actor for his role as spy boss George Smiley in the film adaptation of John Le Carre's novel Tinker Tailor Soldier Spy.
On hearing the news, the Nil By Mouth director said: "This afternoon in Berlin I have learned that I was nominated for an Academy Award in the category of Best Actor.
"You may have heard this before, but it has never been truer than it is for me today, it is extremely humbling, gratifying, and delightful to have your work recognised by the Academy, and to join the celebrated ranks of previous nominees and colleagues. Amazing."
Meryl Streep, who already scooped a Golden Globe for her role in The Iron Lady, said of her best actress nomination: "I am honoured to be in company with such beautiful artists, and touched deeply by my fellow actors for their generosity in giving me this acknowledgement."
The Artist's director Michel Hazanavicius also said he was honoured.
"Filming The Artist in Los Angeles was a dream come true, and to receive this recognition today is far beyond what I ever imagined," he said.
The film's supporting actress contender Berenice Bejo said: "I'm overjoyed and filled with happiness. I can't believe that a year ago I was learning how to tap dance and today I am nominated for an Academy Award."
Best supporting actor nominee Kenneth Branagh, who played Sir Laurence Olivier in My Week With Marilyn, it was "very meaningful" to be nominated for playing a man he had always looked up to.
"If you are an actor, playing a prince of acting, to be recognised by a group of people that know a lot about such things is really touching," he said.
