Who is playing the young Severus Snape? 

Great, that means that Chapter 33 (The Prince's Tale) is going to be in the movie !
The boy is cute, really, and I'm sure he's going to picture a credible-looking young Severus.

:D ;p xD

I have to say, I don't think they did too bad a job with this kid. I mean, I don't know how well he can act, but he's pretty much got the look down (which is more than I can say for some of the other cast!)
