Keira Knightley's movie wig was a real pain in the neck!

London, July 22 (ANI): The wig that Keira Knightley flaunts in her upcoming 18TH century movie The Duchess was so heavy that a resting post was specially made for her to rest her neck between takes.

The 'Bend it like Beckham' star plays the role of a scandalous aristocrat Georgiana Cavendish, Duchess of Devonshire opposite the Ralph Fiennes, in the movie.

And, keeping with the part, she had to pull on a sky-high Marie Antoinette-style wig for several key scenes.

Keira's co-star in the movie Hayley Atwell, who was in LA to promote the flick, movie joked about Knightley's neck aching wig.

"She had to wear this huge wig that was so heavy. They made her a special board that she could lean her shoulders and head against in between takes so she didn't topple over or get neck ache! It was funny," the Sun quoted Hayley Atwell, as saying.

"I loved filming The Duchess. Keira has a great sense of humour - she's really funny," Atwell added. (ANI)
