US Film maker Michael Moore won Palme d'Or, the top Cannes film award for Fahrenheit 9/11,a documentary criticizing President George W. Bush and the White House policies after the attacks of September 11. At the ceremony, that wrapped up the 27th Cannes Film Festival, Michael Moore looked overwhelmed by the jury`s decision. "What have you done?" he asked the jury`s president Quentin Tarantino "You just did this to mess with me, didn't you?"

The jury members said that the decision to award the top prize to Fahrenheit 9/11 was a unanimous choice based purely on the strength of a film, not a political statement. "Fahrenheit 9/11" was one of only three documentaries allowed in competition in nearly 50 years.

The best-actress award went to Maggie Cheung for her role in "Clean" as a junkie trying to straighten out her life and regain custody of her young son. “She is one of the best actresses in the world. In fact that was one of our easier decisions." Quentin Tarantino said, in appreciation of her performance. Fourteen-year-old Yagira Yuuya was named best actor for the Japanese film "Nobody Knows," in which he plays the eldest of four children raised in isolation, who must take charge of the family when their mother leaves.

The festival wrapped up on Sunday with encore screenings of award winners and other key movies, including a combined, four-hour version of Tarantino's two "Kill Bill" installments.
