This LA Times article about the changing role of women in animation offers the first quote I’ve seen from Brenda Chapman since she was kicked off of Pixar’s Brave:
“I think it’s a really sad state. We’re in the 21st century and there are so few stories geared towards girls, told from a female point of view.”
The article goes on to say that she was fired from Brave over “creative differences” and that she is currently on a leave of absence from Pixar, though she will receive a directing credit on the film. My guess — and it’s only a guess — is that she has to remain with the company contractually until the film is completed in order to receive her credit.
