Although Olivia Wilde is one of the most prolific actresses in Hollywood, she's still best known as Dr. Thirteen in House. Why is that? According to her, it's because women in films are really written so flimsily that they're never remembered by the movie-going audience, instead delegated to supporting roles without much effect.
During a panel titled 'The State of Female Justice: Los Angeles', Olivia opens up about the inequality, explaining that when she and a fellow group of actors & actresses did a stage reading of American Pie, but with the gender roles reversed, most of the actors were uncomfortable and bored throughout the read. She explains, "It was fascinating to feel their discomfort [and] to discuss it with them afterward, when they said, "It's boring to play the girl role!" And I said, "Yeah. Yeah. You think? Welcome to our world!"
She adds, "I'm really interested in how we can adjust that, considering that it's all just based on demand." Although really, it's not even about demand anymore. The Hunger Games: Catching Fire was the highest grossing movie of 2013, produced by a woman and starring a woman. Frozen was the third-highest movie of 2013, co-directed by a woman and starring two girls. And don't forget Gravity, which starred Sandra Bullock and is the highest grossing original movie of 2013. Really, when you compare the ratio of movies starring men to women, the movies starring women tend to far better than the movies starring men. This is probably because the sheer volume of movies starring men is so much higher, but really, it's about time Hollywood opened their eyes to the demand.
