The stories about this guy, if true, indicate he is a monster. 

If true, "Hollywood" (including its Studios, Distribution companies, producers, directors, actors, agents, technicians all the way down the food chain) needs to send a strong message and completely shut him and his company out.  The world can live without whatever movies they have under production.

At the very least, Hollywood should put all of his stuff on hold pending resolution.  Yeah, some will be out of work.  Some will take a hit with their money on the line.  BUT, those two things apparently were the driving forces that permitted this sort of conduct.

Hollywood needs to take responsibility for its monster, or the appearance it has a monster, and protect itself.
