"Maisie Williams was topless for real in the photos."

Well not being there I don'[t know but she was of age when she made the film so why not? She does not strike me as someone who would shrink away from what a role demands.

I just about to post a question about the same thing.
We dont see any nudity in any of the "nude" photos due to camera angles, so why would she be topless in them if it doesnt get shown anyway?
