Kidman retreats to tree hideout

Nicole Kidman had to be lured down from a tree on the set of new movie 'Margot at the Wedding' after discovering it was the perfect hideout.

The actress confesses she is a big kid at heart and loved a scene in the film where her on-screen sister - played by Jennifer Jason Leigh - challenges her to climb a tree.

She says: "I love daydreaming. I spend hours up that tree and when they said, 'You can come down.' I said, 'No no, I'm ok.'"
