Julia Roberts pulls muscle while wearing heavy costume

London: ‘Pretty Woman’ star Julia Roberts pulled a muscle in her thigh while filming new movie "Mirror Mirror" after struggling to move in one particularly heavy costume.

The 44-year-old actress stars as the Evil Queen in the fantasy comedy and was often weighed down by her elaborate regal dresses.

The bronze-coloured outfit, which she wears while sitting on her throne in the film, weighed a hefty 60 pounds and Roberts says she had to get ready for the shot in a
specially-erected tent.

"I had a tent on the stage that I went in to dress because that dress doesn`t go into any modern doorway and that dress weighed, I think, 60 pounds. I actually pulled a thigh muscle trying to chastise Nathan, turning really quickly," she said.
