Hollywood beauty Keira Knightley found shooting a graphic outdoors sex scene in DOMINO "undignified" because the director destroyed any notion of romance with his graphic instructions.

The 20-year-old actress and her co-star Edgar Ramirez were left in no doubt what film-maker Tony Scott wanted.

Knightley says, "Filming that sex scene in the middle of the desert being topless with a very beautiful Venezuelan guy? I think I was very lucky!

"A camera went round and round Edgar Ramirez and I while we were acting the scene, with Tony Scott yelling, 'Go on! F**k! F**k!'

"I was like, 'This is so undignified.'"
