The actress playing Austrian kidnap victim Natascha Kampusch has revealed her startling weight loss for the role.

Antonia Campbell-Hughes appeared on the red carpet at Wednesday's 'Frankenweenie' premiere looking shockingly thin.

Campbell-Hughes, who appeared in the 'Lead Balloon' TV series and 'The Other Side Of Sleep' is currently shooting '3096' - so named to signify the number of days Kampusch was held prisoner.

Kampusch was kidnapped at the age of 10 and kept captive in a dungeon by Wolfgang Priklopil for eight and a half years. She was starved and beaten throughout her ordeal.

Priklopil commited suicide shortly after Kampusch escaped in August 2006.

In June Campbell-Hughes told The Evening Standard: "The one thing that I have been adamant about is that I am playing a character in a script.

"It's not a biopic or a case study. But playing someone real, you feel you have to give a bit more. There was an understanding from the beginning that I would suffer as much as she did."
