I must say that about his mother/sister incident this summer, they went to the police for "abuse" of the verbal variety. I remember this because when i heard i thought to myself "Wow, you can get arrested for yelling at you're mom in the UK?"
No one was hurt. I think they said he shoved his mom or sister out of the way when they refused to let him leave the room, and that there was a lot of bashing of his wife going on. Rumor was his sister wanted money from him.
If you read about his family, it seems he's never had a good relationship with his mother (i believe i read that he moved away from her when he was lik 16, to the US with his dad)
Plus she was professional clown.
Clowns, the sketchiest people around.
Anyway, all this aside, i think the guy needs some help. I've heard taht he took the death of Heath Ledger pretty hard, he obviously doesn't have a good relationship with his mom/sister (his father is dead), and obviously has an anger problem. The man is extremely talented, but needs to get his shit together. If this kinda thing keeps happening, no matter how talented he is, people won't want to work with him anymore.
