When did the first woman receive an Academy Award (Oscar) for Best Director?

seen the movie many times. thought Jeremy Renner was great as well as the rest of the cast. I had no idea that a woman directed. you go girl

The Hurt Locker was so good. She also worked on Pint Break a great film… we want more… well deserved,

NumericalChemistry, good God-a woman???

NumericalChemistry, go,go,girl! She is not the only women director but the only one that won an Oscar!

are women are involved in selecting the movies up for awards?
