 I remember reading an Article where J.K Rowling said 
something about telling Robbie Coltrane(Hagrid)and I think Alan 
Rickman(Snape)-(Im not sure if it was him)- about their characters 
more in full detail, like the article said something about telling 
them things about their characters that only she knows about so 
they can get a better idea of what they should be preparing 
themselves for in like the furture movies. I just can't remember 
where I read that, but if anyone here knows anything about it,or 
remembers reading something like it, please let me know :) 
Thanks!
