Hmm, not sure if I would call this greed. The boy seems to have been paid peanuts for a movie that has grossed what is it, 123 million?

The father is a twat and is looking for the high life on the back of his son, but if his father does get the money he can possibly make a better life for himself, and this kind of snowballs down to the kid (i.e treatment of his TB, better food etc). I dont think he should still be living in the condition that he is, the father had to give consent for the boy to do the film and I think he should be in better conditions as his son does live with him.

The guy said he saw none of the money or the house. I think the kid should get more and his father is asking for it as he is a minor (logically).
