Elke Sommer - And Then There Were None (1974)

Elke Sommer, Oliver Reed and Gert Frobe in a scene from the film also known as Ten Little Indians from 1974, when Frobe is trying to fix the generator when the lights go out and refuses to allow Elke Sommer to leave the room with Oliver Reed. Can't think why - maye it was the way he slaps her backside when he ushers her out of the room?
