The female version of Fight Club

Fight Club definitely exhibits a more "male perspective", but I always wondered what the female version of that movie would be. I think this movie definitely qualifies as the film equivalent. The inability of the main character to discern what is real, dual personas, giving into our "Id" personality etc. Also specifically to the male psychology of starting a fight club to beat each other in the face, the female equivalent being the viciousness and competition that women can have with each other in the world of Ballet, not to mention the brutal physicality that goes into the performance of ballet.
