I was racking my brain to come up with ten female directors and I'm three short. I'm mainly interested in directors that have made more than one film. Here's what I have so far, feel free to add more.
Kathryn Bigelow (The Hurt Locker)
Agnès Varda (Cléo de 5 à 7)
Lotte Reiniger (The Adventures of Prince Achmed)
Leni Riefenstahl (Triumph Of The Will)
Margarethe Von Trotta (the Lost Honor Of Katharina Blum)
Mira Nair (Monsoon Wedding)
Jane Campion (the Piano)
