Quick help-

I have an article due tonight on the casting of Harry Potter. I'm lining up cast photos with fan art and discussing where I think the casting was brilliant and where I wonder what they were thinking. This also stretches to costuming, because I'm really only talking about the appearance of each character. (I'll bash Kloves in another review.)

I'm only hitting the first three movies, because I haven't seen enough of Goblet yet. But here's the question:

Here's my list of characters I'm addressing. Am I missing anyone else REALLY important in the first three books?

Harry
Hermione
Ron
Draco
Neville
Ginny
Dumbledore
McGonagall
Snape
Quirrell
Lockheart
Lupin
Hagrid
Sirius
Peter
Potter parents (only because I found a really, REALLY cute picture of Lily I want to use.)

Am I missing anyone crucial????
