Is there a movie you would have liked to see Helena in?

yeah there's the White Witch of The Chronicles of Narnia and i already made a pick about that link
and there's also Tia Dalma from Pirates of the Caribbean, i know the actress (i dunno her name) was good but the role fits Helena as well, i can clearly imagine her as Tia Dalma

I know she's too old but, Princess Azula in The Last Airbender.

For some reason, I can actually see her doing the voice of the "Other Mother" in Coraline. Don't ask why I just think she could portray that character very well.
