Nicole Kidman as AdelinaEdit
With seeing Nicole Kidman in variety of roles, I feel that Adelina would be perfect for her. In Batman Forever she was a Doctor who was obsessed over Batman. In The Others she plays a strict catholic mother trying to keep her children safe from the sun. With just these to roles in mind I can see her as a nun lost from the path of saving Lorien and able to snap back to realty to protect Marina when the time is right.
