I'm surprised the rat doesn't have his own deck chair with his real name on it! LOL

He's known Rickman for 20 years? :o No fair! LOL It does sound like Lupin and Sirius are best mates in real life and it can only bode well that Rickman, Spall, Thewlis and Oldman know each other so well. It can kinda make the acting more solid, they all understand each other. I wonder if WB knew they all knew each other and planned it that way? LOL
