i have'n't seen the movie (don't really want to as well) but wasn't sirius supposed to look skeleton like..... with hair till his elbows, and you could only see he was alive in the picture, because he blinked sometimes..... i saw a preview from the movie, and he was screaming and going crazy in the picture! can't they keep a bit more to the books!! and i think johnny would be very good for this! you can make everyone look scary, even him, he is the best actor ever, and even when you make him look scary, you can still see he looked handsome once! wasn't that what sirius was supposed to be!!! (sorry, long story again)
The movie didn't really keep to the book overall so what's the point? Anyway, I love Johnny but he's too good looking for the part. And in the book when they said he was handsome once, I took it as not hot, but just more normal looking. I think it would make more sense for Sirius not to look so young because how are you supposed to look after 12 years in Akaban?
I preferred Gary Oldman for Sirius. The one problem was those stupid tattoos on his chest. Where were those in the book??
Johnny Depp is too much a pretty boy for Black. He'd work as a student how young he looks for his age. Or atleast on of the quidditch players in the tourny (forgot the main quidditch guys name XD)
