I was hoping!

I recently saw "Stay Alive", a horror film that is about a video game that kills people who play it (if they die in the game). the game in the movie is based on "The Blood Countess - Elizabeth Bathory". I never had heard about this woman. I have since read about her and what she had done to the young women. Since reading about her I was hoping they would make a film about her. Does anyone know of any sites that really go into depth about her? Thank you
