Julia Roberts pulled a muscle in her thigh while filming new movie "Mirror Mirror" after struggling to move in one particularly heavy costume.
The actress stars as the Evil Queen in the fantasy comedy and was often weighed down by her elaborate regal dresses.
One bronze-colored outfit, which she wears while sitting on her throne in the film, weighed a hefty 60 pounds and Roberts admits she had to get ready for the shot in a specially-erected tent.
During an interview with talk show host Ellen DeGeneres, she said, "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."
And the heavy material even left Roberts with an injury after filming scenes with co-star Nathan Lane.
She added, "I actually pulled a thigh muscle trying to chastize Nathan, turning really quickly."
