Question about the crystal ball scene

[jeanico2000]

I just got back from vacation, so didn't have too much time to go 
through all the posts. I saw the film for the second time today (the 
first time was at the actual premiere in New York, which was 
amazing), and I was wondering who's face it is that we see in the 
crystal ball, calling out Harry's name? Anyone recognize who it is?
Thanks!

PS: I loved the movie, by the way. So much eye candy! such 
cinematography! and that scene with Harry on Buckbeak... my absolute 
best goosebump moment, that was! I think that I learned the trick to 
loving these HP movies... don't compare the films to the books, 
whatever you do. Just go with an open mind and enjoy the movie for 
what it is. Pure magic and much needed fantasy!
