Just a quick question for our resident and esteemed Japanophiles here.

I'm looking for the title of a Japanese movie I really want to show my wife.
I've seen it before, late one night, but never caught the title.
It has two aspiring actresses living together and vying for the same part in a production. One girl is an academic, high achiever from a rural area and the other is more urbane (and slutty).
In the end they end up beating each other to death.

It truly is a great film.

Any assistance or information on it is highly appreciated.

Thank you.
