Dress trouble for Julia Roberts

London, March 26 (IANS) Oscar winning actress Julia Roberts' costume was so heavy that she pulled a muscle in her thigh while filming for the movie "Mirror Mirror".

The bronze-coloured outfit weighed 60 pounds (27.2 kilograms) and Roberts admits she had to get ready for the shot in a specially-erected tent, reports femalefirst.co.uk.

"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," she told in an interview with US talk show host Ellen DeGeneres.

"I actually pulled a thigh muscle trying to chastise Nathan, turning really quickly," she added.
