Casting Questions

[Tamara <buffyeton@yahoo.com>]

Okay, as I feel I should cast all the HP movies from now on (I should 
have started at the beginning with Harry et.al but oh well), I have a 
few questions.  Now I've read the books, over and over and over, but 
still can't get a total grasp on some of the characters.  So please 
answer these:

Remus Lupin:
How old:
Looks:
Personality traits:

Sirius Black:
How old:
Looks:
Personality traits:

Thanks as always!
