Kruger's On-set Ballet
German actress DIANE KRUGER passed time on the set of new movie NATIONAL TREASURE: BOOK OF SECRETS by treating cast and crew to ballet recitals. The 31-year-old was a talented dancer as a child - and used the art form to fight of bouts of boredom between scenes. She says, "I studied ballet but had to quit when I was 14. I was going around performing all of the classics - Swan Lake and all that."
