The 'Pride and Prejudice' star disrobed before plunging into a deep
fountain and emerging soaking wet in a clingy slip.

The film's director Joe Wright is quoted by Britain's Daily Express
newspaper: "I wanted to cast Keira as a woman, a sexual character. She's
only ever played girls before.

"There is a key scene with James McAvoy where she dives into a deep fountain
to retrieve a broken vase. Keira emerges from the water and stands on the
fountain's edge. It was her idea to stand there for quite so long - but I
quite liked it."

He said: "There was another shot of her from behind but we left it out as it
seemed a bit too rude."

Keira has flashed her flesh in a number of previous films, including 'The
Jacket', 'Domino' and 'The Hole' - in which she exposed her breasts.
She recently admitted she loves stripping naked in her movies and finds sex
scenes "liberating".
