Kidman sets aside keepsakes for kids

Nicole Kidman has created time capsules for her adopted kids full of letters she writes to them from the set of every film.

The actress pens heartfelt notes to son Conor and daughter Isabella as she starts each film and then locks them away together with other keepsakes the kids won't see until they're 18.

She says: "On every film I write a letter to each of them so that they know what they helped me with in terms of a role because there's a lot of downsides to having a mother who's an actress.

"At the same time you can watch your mother when she's long gone in films and see her. If you've also got the letters that are attached to each role that's kind of interesting.

"So they both have a box of things waiting for them when they're 18."

Meanwhile, film-maker Jonathan Glazer found it tough to direct Nicole Kidman in his new movie Birth, because he didn't realise she'd be hounded by the paparazzi.

The director admits he was "a little naïve" when it came to shooting some location scenes in New York's Central Park, because he couldn't drive the press away.

He says: "Anywhere Nicole went there were hundreds of paparazzi. In fact we shot a carriage scene in Central Park and on either side of her were 30 paparazzi on one side and 30 on the other, running alongside: 'Click, click, click.'

"It was a circus, the whole thing, and I was in the big top for that day. That was the worst part of it."
