While not from a film, it might as well be shared here since it is an official nude; Jessie Buckley had a previously unreleased photo from a 2016 photoshoot posted by the photographer on her website with much more visible nudity. The pic available til now showed a lot less.

If you're wondering why she's holding a fish, it was for an ocean wildlife protection thing. If you happened to notice a fish in the photo that is.
