Audrey Hepburn, 1955 - this extreme rotation of the neck requires a slight tilt of the head, here with the face downward, due to the angles of the vertebral bones in the neck. Audrey is demonstrating this beautifully.
Audrey Hepburn ~ During production of Sabrina Billy Wilder was continuously working on the script. One day he asked Hepburn to feign illness so he would have enough time to finish the scene to be shot. Audrey looking stunning 😊
