The film is named ‘3096’ after the number of days she was imprisoned by kidnapper Wolfgang Priklopi (played by Thure Lindhardt) and will detail the years Natascha was held hostage from 1998 until her escape in 2006.

She’s just the latest actor to shed the pounds for a film role, with Matthew McConaughey snapped earlier this week looking dangerously thin. He’s playing AIDS sufferer Ron Woodroof in his forthcoming movie 'The Dallas Buyer's Club'.
