Amber Heard was up the role, I doubt she would still be while she is busy with Aquaman.

I would say Jessica Chastain (interstellar) but I fear her sjw streak is too strong and she would not allow the sexy costume which is inherently required (fuck you if you disagree.)

Evan Rachel Wood (westworld) & Deborah Ann Woll (netflix's daredevil) would be my next choices but I question if they have the ferocity the character requires.
