Brotherhood of Evil Casting

[MercuryEnigma]

I know they're pretty much done with X-men, but who would you cast as the original Brotherhood of Mutants. Obviously Magneto and Toad would be Ian McKellen and Ray Park (and Kevin Durand if you wanted to include Blob), but what about Scarlett Witch, Quicksilver and Mastermind?

So far I'm thinking
MASTERMIND-
David Thewlis

with Michael Berry and Jr.Mackenzie Crook as runner ups

QUICKSILVER-
Christian Campbell (thanks to Otto Octavius)

SCARLETT WITCH-
???

UNUS THE UNTOUCHABLE-
Who cares?

This is a pretty mundane and moot thread; I'm aware. And I'm not even sure this should be in the General Movies Board. The reason I started this thread, because I've begun to work on a classic Brotherhood manip and I'd like your input. Plus I love these casting threads.

Somebody on another thread suggested Eliza Dushku for Scarlet Witch. I kinda like that idea.
