In an interview with French Elle, actress Emmanuelle Seigner, 43, revealed that her husband, director Roman Polanski, 76, is at work on a big-screen adaptation of the Tony-winning play God of Carnage. Polanski has been under house arrest in Switzerland since December, when he posted bail after Swiss police apprehended him in connection with his 1978 conviction for having sex with a 13-year-old girl. The Oscar-winning director is also finishing post-production on The Ghost Writer (out Feb. 19), a political thriller starring Ewan McGregor and Pierce Brosnan. God of Carnage, written by Polanski’s friend Yasmina Reza, is still running on Broadway after winning Best Play at the 2009 Tony Awards.
