Re: Emily Blunt = Scarlet Witch?
It is a possibility.
I enjoyed her performances in Looper and The Wolfman.
It depends on how the character is written and designed (and I hope to God they do not use the *****-ass trenchcoat design from the Marvel Now redesign.)
"I defeated your uncle Victarion and his Iron Fleet off Fair Isle, the first time your father crowned himself. I held Storm's End against the power of the Reach for a year, and took Dragonstone from the Targaryens. I smashed Mance Rayder at the Wall, though he had twenty times my numbers. Tell me, turncloak, what battles has the B---- of Bolton ever won that I should fear him?"
One of the best soundtrack sections. Ever.
