LOS ANGELES - BLEAK drama No Country For Old Men won four Oscars on Sunday, more than any other film, including best movie, director and adapted screenplay for brothers Joel and Ethan Coen.

The movie, based on Cormac McCarthy's novel about a drug deal gone wrong in south Texas, speaks to the moral decline of society and was among a group of dark, somber films that competed for the world's top movie awards.

The film's fourth award, for best supporting actor, went to Spain's Javier Bardem for playing a killer of few words.

In other top awards, members of the Academy of Motion Picture Arts and Sciences honored a wide range of movies, actors and actresses from several countries, highlighting a recent trend toward globalization in cinema.

But Hollywood's biggest night belonged to the Coens - offbeat filmmakers who have shown a skill at taking what could be mundane stories, populating them with quirky characters and looking at troubling questions of human frailty.

Accepting his Oscar, Joel Coen talked about how he and Ethan had made films since they were kids and said his brother had taken a camera to the airport as a boy in the 1960s to create 'Shuttle Diplomacy: Henry Kissinger Man on the Go.'

'Honestly, what we do now doesn't feel that much different from what we did then,' he joked.

Best Actor
Briton Daniel Day-Lewis won for best actor as a sadistic oil prospector in the early 20th century whose rise to wealth and power comes at a deep cost to his soul.

He was heavily favored for an Oscar after winning a series of other industry awards for the role.

Another British performer, Tilda Swinton, took supporting actress honors as a shifty lawyer in the thriller Michael Clayton and France's Marion Cotillard was named best actress for portraying singer Edith Piaf in La Vie en Rose.

Speechless Cotillard
If there were an Oscar for the standout star of Sunday's Academy Awards ceremony, it would have to go to France's best actress winner Marion Cotillard.

The 32-year-old won for her portrayal of legendary chanteuse Edith Piaf in La Vie en Rose and she shone throughout the evening with her body-hugging, mermaid-style dress, boundless energy and a farewell song backstage.

Cotillard set the tone from her entrance on the red carpet, where her full-length white and gold Jean Paul Gaultier gown was a refreshing departure from the predominant red.

'I'm totally overwhelmed with joy and sparkles and fireworks and everything that goes like 'boom boom boom',' the bubbly brunette laughed when asked by reporters backstage to describe how she felt after receiving her golden statuette.

In reply to a question about her screen idols, she said:'I'm a very big fan of Peter Sellers. I wanted to marry him when I was a child.'

She also gave a short rendition of the famous Piaf number 'Padam Padam,' prompting loud applause from reporters.

Cotillard was the first French performer since 1960 to win an Oscar in the best actress category. The victory, earned from her first Oscar nomination, will have raised her profile in Hollywood overnight.

Cotillard stunned audiences and critics at home and abroad with her physical transformation in the film that traces the life of Piaf, who achieved international fame after being raised by her grandmother in a brothel but saw her life cut short by drug and alcohol abuse.

The win comes just days after Paris-born Cotillard took home the French film industry's coveted Cesar award for best actress for La Mome, as the Piaf biopic is called in her homeland.

She also picked up a British Bafta and a Golden Globe for her role.

Supporting actor winner: Bardem
Bardem took the occasion to thank his family in Spanish, apologising in advance to the Hollywood audience.

'This is for Spain and this is for all of you,' he said.

The Austrian Holocaust-era drama The Counterfeiters won the Oscar for best foreign language film.

Directed by Stefan Ruzowitzky, it was the first win for Austria in the category.

In other key categories, best animated film went to audience favorite and box office hit Ratatouille about a friendly rat who becomes a chef in a Parisian kitchen.

Juno gets one
Best original screenplay went to stripper turned writer Diablo Cody for the hopeful teen pregnancy comedy Juno.

Despite the talk of dark and pessimistic movies at this year's Oscars, many winners offered statements of optimism.

Perhaps the most inspiring came from Marketa Irglova who, along with Glen Hansard, won for best original song with the tune Falling Slowly from the low-budget movie Once.

Until the film won over audiences, Irglova and Hansard were unknown.

'This is just a proof that no matter how far out your dreams are, it's possible, said Irglova.

'This song was written from a perspective of hope and hope connects us all.'

Director Alex Gibney of documentary winner Taxi to the Dark Side - a look at the use of torture by the United States - also offered a message of optimism.

'Let's hope we can turn away from the dark side and return to the light,' Gibney said.

Political satirist Jon Stewart returned as Oscar host and, in his opening monologue, made light of that pessimistic tone of many of the best film nominees.

'Does this town need a hug? What happened?' Stewart said.

What happened? Oscar hugged the Coens.
