which of the actors play their parts to beautifully that あなた feel like they have just popped out of the books??

I would say all of them.
I can't imagine anyone else playing the characters.Evana Lynch was great.Also Alan Rickman.

Most of them. The HP 映画 gathered one of the best cast ever reunited for a movie, both among the older and the younger alike.

Alan Rickman as Severus, Maggie Smith as Minerva, Imelda Staunton as Umbridge, Emma Thompson as Trelawney, Michael Gambon as Dumbledore, Ralph Fiennes as Voldemort, Helena BC as Bellatrix, they are my favs. But honestly, they are all so good, so wonderful, that I'd like to say 'All of them !'

Alan Rickman, Rupert Grint, Tom Felton, Maggie Smith, Julie Walters, Helena Bonham Carter and till OotP Jason Isaacs and Gary Oldman did quite fine too.

I think for me it is Evanna Lynch and Tom Felton. They where exactly like I imagined Luna and Draco when I read the books.

Alan Rickman - he portrayed the man with his pain buried within him perfectly, but also the man 表示中 this pain for Lily perfectly.
Evana Lynch - From her soft, dreamy voice to her permanent slightly surprised expression, "Evana doesn't play Luna, she is Luna."
Ralph Fiennes (Voldemort)- Terrifying, believable, cold... he nails it. That's why him hugging Draco was so strange, and funny.
Tom Felton - He plays the arrogant, cowardly, troubled boy so well that when I actually see him in an interview i expect him to say something nasty about mudbloods XD
Also, Emma Watson as Hermione, Maggie Smith as Professor McGonagall, and Matthiew Lewis as Neville!
