"The Artist" was the big winner at last night's Oscars, winning five Academy Awards including best picture and becoming the first silent film to triumph at the Academy Awards since the original Oscar ceremony 83 years ago.
The black and white film - which tells the tale of an old-Hollywood love story - was named Best Picture, while its star Jean Dujardin took Best Actor and Michel
Hazavanicius took home the award for Best Director.
Accepting the Best Actor accolade, first-time nominee Jean, 39 - who saw off stiff competition from Hollywood stalwarts Brad Pitt and George Clooney - gushed: "I love your country. So many of you here tonight have inspired me."
The film also scooped the awards for Best Costume Design and Best Original Score.
Meryl Streep wins Best Actress
Seventeen-times nominated star Meryl Streep was named Best Actress for her portrayal of former British Prime Minister Margaret Thatcher in 'The Iron Lady'.The 62-year-old third-time Oscar winner kissed husband Don Gummer before taking to the stage at Los Angeles' Kodak Theatre to accept her iconic Oscars statuette.
She joked: "When they called my name I had this feeling I could hear half of America going, 'come on, why her again', but whatever."
Praised by award presenter and her 'Mamma Mia!' co-star Colin Firth for being "unreasonably good", she thanked her colleagues and friends for her "inexplicably wonderful career".
Streep's win was her first Oscar in 29 years, since she won best actress for "Sophie's Choice." She had lost 12 times in a row since then. Streep also has a supporting-actress Oscar for 1979's "Kramer vs. Kramer."
"When they called my name, I had this feeling I could hear half of America go, 'Oh, no, why her again?' But whatever," Streep said, laughing.
"I really understand I'll never be up here again. I really want to think all my colleagues, my friends. I look out here and I see my life before my eyes, my old friends, my new friends. Really, this is such a great honor but the think that counts the most with me is the friendship and the love and the sheer job we've shared making moves together," said Streep, the record-holder with 17 acting nominations.
Another big winner of the night was Martin Scorsese's 3D adventure drama 'Hugo' which was victorious in the categories of Best Cinematography, Best Art Direction, Best Sound Editing, Best Sound Mixing and Best Visual Effects.
