Snape in CoS

[susanbones2003 <rdas@facstaff.wisc.edu>]

I just saw CoS for the nth time (can't divulge such topsecret info) 
but I wondered if anyone knew anything about the filming of the 
project. In his first scene, Alan Rickman looks ill. Like he just had 
all his wisdom teeth out or something. Next scene he's in, he looks 
fine,(the one where they discover Mrs. Norris). But in that first 
scene where he confronts Harry and Ron just back from a bit of 
dancing with the Whomping Willow, his face is very weird, pale, paler 
than normal and puffy. Among the other strange things I'd like to 
know about is the order of filming the scenes. Is there anyway to 
find out that sort of information?
