Hugo Weaving as Elrond or Agent Smith

I would choose "both" it that was an option...

Anyways, Agent Smith. He is great as Elrond too, but Weaving showcases his abilities as Smith better, I think.

BTW, I love Hugo Weaving's articulation. 

Smith: I killed you, Mister Anderson, I watched you die… With a certain satisfaction, I might add, and then something happened. Something that I knew was impossible, but it happened anyway. You destroyed me, Mister Anderson. Afterward, I knew the rules, I understood what I was supposed to do but I didn’t. I couldn’t. I was compelled to stay, compelled to disobey. And now here I stand because of you, Mister Anderson, because of you I’m no longer an agent of the system, because of you I’ve changed – I’m unplugged – a new man, so to speak, like you, apparently free.
Neo: Congratulations.
Smith: Thank you. But as you well know, appearances can be deceiving, which brings me back to the reason why we’re here. We’re not here because we’re free, we’re here because we’re not free. There’s no escaping reason, no denying purpose – because as we both know, without purpose, we would not exist.
Smith 2: It is purpose that created us,
Smith 3: Purpose that connects us,
Smith 4: Purpose that pulls us,
Smith 5: That guides us,
Smith 6: That drives us,
Smith 7: It is purpose that defines,
Smith 8: Purpose that binds us.
Smith: We’re here because of you, Mister Anderson, we’re here to take from you what you tried to take from us. Purpose.

He also plyas good in the Mortal Engine, a real cool post acopalyptic movie. He can both do convincing villain and convincing, intelectual supportive character. Similar vain to William Dafoe
