Kathryn Bigelow is the first woman in the 82-year history of the Oscars to earn Hollywood's top prize for filmmakers.
"There's no other way to describe it. It's the moment of a lifetime," Bigelow said. "It's so extraordinary to be in the company of my fellow nominees, such powerful filmmakers, who have inspired me and I have admired, some of them for decades."
Cameron was seated right behind Bigelow at the Oscars and joined a standing ovation for her, clapping vigorously and saying, "Yes, yes" after she won.
First-time winners took all four acting prizes: Sandra Bullock as best actress for "The Blind Side"; Jeff Bridges as best actor for "Crazy Heart"; Mo'Nique as supporting actress for "Precious"; and Christoph Waltz as supporting actor for "Inglourious Basterds."
"Avatar" won three Oscars, for visual effects, art direction and cinematography, beating "The Hurt Locker" for the latter. "The Hurt Locker" also won out over "Avatar" for film editing, sound editing and sound mixing.
With nine nominations each, "The Hurt Locker" and "Avatar" came in tied for the Oscar lead.
"Hurt Locker" screenwriter Mark Boal, who won the Oscar for original screenplay, thanked Bigelow, calling her an "extraordinary and visionary filmmaker," and dedicated his Oscar win to the troops still in Iraq and Afghanistan, along with those who did not make it home. Boal also affectionately recalled his father, who died a month ago.
Missing from the onstage celebration for the "Hurt Locker" win was producer Nicolas Chartier, who was banned by the academy from attending the Oscars because of e-mails he sent urging members to vote for his movie which is an academy violation.
"The Hurt Locker" took home six Oscars, best picture, best director, film editing, sound mixing, sound editing, and original screenplay.
It was awesome to watch as history unfolded last night. She sets the way for future women filmmakers. Absolutely awesome.
