Harry Potter Casting News: Emma Thompson will play Sybil Trelawney, Harry’s dreaded Divinations teacher, in Prisoner of Azkaban. Cool. I kinda pictured Sybil as older, but I’m sure Emma will be able to pull it off. (Luckily Gilderoy’s not around in this one, huh?) Although, what’s this about the movie not coming out til next June? I thought we could expect it this year, same as the last two. Damn.
