Tough one, isn't it? ;D

Both, but for me Helena wins every time :D

Really hard... I love Helena as Bellatrix but Alan as Severus is just more than perfect *o*

i think itz pretty much a tie
dey both r awsum and i cant imagine any1 playing these roles instead of dem

Both of them fit their roles so perfectly

she still did AMAZING as belltrix! but alan was perfect!

Well that was hard. >.<

:D Bellatrix/Helena!!!!!

I would have said tie, but Alan is just PERFECT!

Alan Rickman is the perfect Severus Sanpe for me. Infact Alan is perfect for any goddamn role :P

Tough question... They both were so good. Helena conveyed Bellatrix' bloodthirst and madness and psychosis extremely well.

But Alan... he is Severus. The voice, the presence, the gaze (and glares), the self-control, the might, the maleness, the emotions he felt when about to die, all this would have deserved an Oscar and/or a BAFTA award.

I wound up clicking on a random answer because I couldn't decide.

Bella too but like others have said, Alan IS Snape

Wow. That was tough!

Alan Rickman did an overall fantastic job at playing Snape - so much that I bounce in my seat with excitement whenever he comes on the screen. xD

Amazing performance he was perfect for the role of Snape no0one will ever replace him.
But Helena as Bella was amazing too

There's no way I can pick. They are both really really good.

Tough...

Both!

Both. I wouldn't have enjoyed watching the movies anywhere near as much without those 2 actors in it. Whenever they were on screen my eyes were always riveted on them. Even when they were only in the background.
