The Artist has swept the board at the Oscars, taking home a total of five statuettes including best film and best actor for Jean Dujardin.
Dujardin was so delighted he swore as he accepted the award. He is the first Frenchman to win the best actor Oscar and beat strong competition from George Clooney, in The Descendants.
Silent, in black and white and in French, The Artist was a triumph for director, Michel Hazanavicius, who also took the Oscar for best director. It also won best original score and best costume design.
As he accepted his award, Hazanavicius said: "I am the happiest director in the world right now."
The Martin Scorsese 3D film Hugo, which follows the adventures of a young boy living in a Paris train station in the 1930s, also won five awards for best cinematography, art direction, visual effects, sound editing and sound mixing.
Writer/Director Woody Allen took the Oscar for best original screenplay for Midnight in Paris, losing out to Michel Hazanavicius in the top directing prize.
