The man doesn't even have to say anything and he still owns every second he's on screen.

Rickman altered my vision of Snape from the books with his sheer awesomeness...and then some. I am almost certain he IS Severus Snape :)

TeddyBear, he is. ;)

Each and every single one of these people are extraordinary actors and actresses, and they have all done phenominal jobs with their roles. I have honestly not been this happy with a book-to-movie cast since Lord of the Rings, and trust me, that's really saying something. I love these people.

They are all very good, a dream cast, to say the least.

But my fav is Alan. He is Severus Snape, in voice, in looks, in presence, in attitude, in humor, in face expressions, in... everything ! Oh, I forgot : in sexiness !

Who else?

Even though he's much older than Snape, I don't think anyone else could have played his character as well. I do like Helena next.

IDK who any of these people play. Except the Snapes...

Helen is AMAZING, shes wonderful, but she doesnt compare to Alan, hes just the perfect Snape, his acting is done so beautifully it almosts makes me feel like all od this is real

They're all so talented!

2nd Fiona Shaw
3rd Helena, Julie, Maggie & Emma

and Helena is Tied for me,both of them is Awesome and really good to act,and not only in HP. I also think Maggie,Ralph,Emma and Michael is really good too:D

holy shit that was hard. But my vote goes to Jason...i love him in most of his movies...not just HP. He is amazing.

Where is Kenneth Branagh? I was in love with him ever since he played Hamlet :)

I <3 her and Alan!!

So hard to choose! Jason, Helena, Alan, Ralph, Gary, Timothy, Emma..

And Alan!

definitely!

I agree with Mongoose09

They are all really good actors, but I was between Alan, Ralph and Gary.

My favourite actor ♥

Honestly, all of them were amazing! And still are, of course...
