"There's no other way to describe it, it's the moment of a lifetime," said Bigelow at the awards ceremony in Los Angeles on Sunday．She has become the first female ever to win a Best Director Oscar．
Bigelow was up against the top-selling film of all time, Avatar．But Bigelow's smallbudget film, The Hurt Locker, swept the awards with six trophies （奖杯） , including Best Director, Best Original Screenplay, Best Sound Mixing and the big one: Best Picture．
Many Hollywood insiders are calling this year’s awards the "Indie Oscars", with smaller films taking the other top awards．This was due in large part to outstanding individual performances: Jeff Bridges in Crazy Heart （Best Actor） and Sandra Bullock in The Blind Side （Best Actress）．But all eyes were on Bigelow, as her movie The Hurt Locker beat Avatar to the major awards．This was sweetened by the fact Avatar's director, James Cameron, is her ex-husband．
Bigelow was only the fourth female ever to be nominated （提名） for Best Director．She followed in the footsteps of Lina Wurtmuller, for Seven Beauties （1976）; Jane Campion, The Piano （1993）;and Sophia Coppola, Lost in Translation （2003）．
Bigelow played down the important occasion last week, telling CBS, "There's really no difference between what I do and what a male filmmaker might do．I mean we all try to make our days, we all try to give the best performances we can, we try to make our budget, we try to make the best movie we possibly can．So in that sense it's very similar．On the other hand, I think the journey for women, no matter what field it is—politics, business, film —it's a long journey．"
Ironically Bigelow's filmography is filled with action movies that are low on female leads and high on guns and steel．Her films such as Point Break and The Hurt Locker focus on the fears of men．
And is there an entertaining end to the story of Bigelow's victory? She won on International Women's Day．
It is, after all, Hollywood．
