Just finished watching Voice from the Stone. It is a slow burn of a movie. Emilia Clarke is indeed nude in the film, however, the previous reviews were incorrect. Perhaps they saw an earlier edit of the film and they used alternate scenes in the final cut.
58:00- Emilia disrobes to pose for a sculpture. It is just shy of a full frontal when the robe comes off and she lays down. Her legs are closed though so no lower frontal nudity. We do however see both breasts clearly. Throughout this scene, her breasts are on display numerous times before she eventually gets up and leaves.
1:00:00- Around this time we do get a masturbation scene with her interspersed with footage of the father sculpting. However she isn’t nude during the masturbation. She is clothed and under the covers in bed. We get a couple of shots of her writhing and moaning though.
1:06:00- The sex scene occurs here. We do see Emilia on top for a short time and her breasts are again clearly on display.
Voice from the Stone is currently available for VOD rental and purchase though.
