The previous oldest winner was best-actress recipient Jessica Tandy for “Driving Miss Daisy,” at age 80.
Completing an awards-season blitz that took her from Hollywood bit player to star, Spencer won for her role in “The Help” as a headstrong black maid whose willful ways continually land her in trouble with white employers in 1960s Mississippi.
Spencer wept throughout her breathless speech, in which she apologized between laughing and crying for running a bit long on her time limit.
“Oh, thank you. Oui. I love your country!” said Dujardin, who plays George Valentin, a silent-film superstar fallen on hard times as the sound era takes over. If George Valentin could speak, Dujardin said, “he’d say … ‘Merci beaucoup, formidable!’”
Claiming Hollywood’s top-filmmaking honor completes Hazanavicius’ sudden rise from popular movie-maker back home in France to internationally celebrated director.
Hazanavicius had come in as the favorite after winning at the Directors Guild of America Awards, whose recipient almost always goes on to claim the Oscar.
The win is even more impressive given the type of film Hazanavicius made, a black-and-white silent movie that was a throwback to the early decades of cinema. Other than Charles Chaplin, who continued to make silent films into the 1930s, and Mel Brooks, who scored a hit with the 1976 comedy “Silent Movie,” few people have tried it since talking pictures took over in the late 1920s.
The only other filmmaker from France to win the directing Oscar is “The Pianist” creator Roman Polanski, who was born in France, moved to Poland as a child and has lived in France since fleeing Hollywood in the 1970s on charges he had sex with a 13-year-old girl.
Hazanavicius, known in his home country for the “OSS 117” spy comedies but virtually unheard of in Hollywood previously, won a prize that eluded half a dozen of France’s most-esteemed filmmakers, including Jean Renoir, Francois Truffaut and Louis Malle, who all were nominated for directing Oscars but never won.
The five Oscars for “Hugo,” which led contenders with 11 nominations, included cinematography, art direction and visual effects.
The visual-effects prize had been the last chance for the “Harry Potter” franchise to win an Oscar. The finale, “Harry Potter and the Deathly Hallows: Part 2,” had been nominated for visual effects and two other Oscars but lost all three. Previous “Harry Potter” installments had lost on all nine of their nominations.
The teen wizard may never have struck Oscar gold, but he has a consolation prize: $7.7 billion at the box office worldwide, including $1.3 billion from “Deathly Hallows: Part 2,” last year’s top-grossing movie.
“And yet they only paid 14 percent income tax,” Oscar host Billy Crystal joked about the “Potter” franchise.
