The Artist completed its sweep of the awards season by winning Best Picture at the 84th Annual Academy Awards. 

Producer Thomas Langmann thanked director Claude Berri for being a positive influence on him, while director Michel Hazanavicius mentioned Billy Wilder (three times). 

A beaming Jean Dujardin won the Best Actor trophy and, in his acceptance speech, exclaimed "I love your country" and "Merci beaucoup, I love you!"

In a tight battle for Best Actress, Meryl Streep nabbed a third Academy Award following her 17th Oscar nomination for her performance in The Iron Lady.

"I had a feeling I could hear half of America go, 'Oh no' ... 'Not her again,'" she said to a standing ovation, holding aloft her third Oscar statue. Her two previous wins were for Kramer vs. Kramer in 1979 and Sophie's Choice in 1982.

"I really understand I'll never be up here again," she said. "This is such a great honor, but the thing that counts the most with me is the friendships, and the love, and the sheer joy we have shared making movies together."
