Moviemaker JOE WRIGHT was left red-faced on the set of new period piece ATONEMENT when he was heard yelling masturbation instructions to actress Keira Knightley. Wright pumped Brian Eno's tune This onto the set at full volume for the film's sensual scenes - but was caught out one morning when the track ended unexpectedly. He says, "I didn't reduce the volume of my voice and I could suddenly be heard shouting, 'Keira, w**k him off,' which I was mercilessly ripped about for some weeks afterwards." But the actress insists there was "no knob-touching for real".
