The Horse Gets Paralyzed

The movie is about a man who went crazy and shot his head of security. He had aspirations to host like the US Olympic weightlifting or wrestling team at his house. Mark Ruffalo plays the brother, the one that was like murdered. The horse got paralyzed? No. His balls got ripped off on a fence. So he wasn't able to think anymore because he was functionally a woman. And then he also had schizophrenia.
