I think all of these are really fitting :)

thats how I imagined her when I read the book

Also Dumbledore.. but the one in the first 2 films.

Agreed! The first Dumbledore was perfect.

ginny is smart liyal and sweet

All of them, but Snape is just.... wow, scary!! X) haha

Albus Dumbledore was perfect in the first 2 films...but with the second actor they've made him more aggressive, and less regal

Snape, Hermione, Luna, Draco, Mcgonagall and Dumbledore were pretty much what i envisioned them to be, now i couldnt imagine Voldemorte looked like im really impressed how Ralph Finnes brought him to life thats awesome~!

I love Alan Rickman's Snape but he isn't exactly how I pictured him when I was reading the books. I think McGonagall is the one who is most similar to what I imagined.

Alan Rickman is the perfect Snape.

Bella, Lord Voldemort, Snape, Draco & Sirius were as I imagined

Definetly Draco. Then Hermione and then Snape. Alan Rickman is fabulous.

i read the books after i look at they 5 first movies,but only i can see for me its snape, i think they others had diffrent looks in the movie and in the books,Ron and Harry was longest away for me.

i think most of them did a great job :)

snape is so cool

The book makes Draco seem ugly, it makes Voldemort look not scary... and it makes Harry wimpy-looking! Don't get me started on anyone else!

The only complaint I have about the casting is Dan's eyes are BLUE! As for Snape he's right on the money of how I saw him. I only count the first two movies for the casting of the kids. They didn't know how they would grow up

The only problem I ever had with Alan Rickman is that he looks his age. Snape is a very young man in the books, and Alan Rickman is not. Other than that, he is spot on. Jason Isaacs, on the other hand, besides loving everything Harry Potter and really relishing the fact he is privaledged as he is to be in these films, he is Lucius to a T. And you can also tell he really likes what he is doing.

bellatrix onthe other hand is quite diffrent than i imagned, i thought she had stright hair in the book, not curly

I think McGonagall and Ron are amazing too (maybe not appearance wise, but they definitely have the right personalities and mannerisms).

Alan Rickman is perfect all around.

I was really nervous about how Luna was going to be portrayed, I was really pleased with Evanna, she's done a really good job IMO.

Snape
Belletrix
Mcgonnagal
Lucius
Dumbledore
Draco are not bad either really.

and Snape and Richard Harris' Dumbledore

And Minerva and Luna and Lucius!
