Roman Polanski is finishing the edit of his latest movie “Ghost” from his house arrest in Switzerland, surrounded by family and bombarded by telephone calls of support, French philosopher Bernard-Henri Levy said in an interview Sunday. Levy, a friend of the 76-year-old director, told the Lausanne-based weekly Le Matin Dimanche that he visited Polanski in his chalet in the luxury Swiss resort of Gstaad about 10 days ago and found him like “a rock,” working and confident, even though his family is worried about the US extradition request hanging over him. He said he was able to have a friendly dinner with Polanski in the chalet. Being able to entertain at home was one of the privileges the director received after his Dec. 4 transfer to house arrest from a Swiss jail after more than 60 days of detention. Polanski's two children - Elvis, 9, and Morgane, 16 - and his wife, French actress Emmanuelle Seigner, have been staying in the chalet with him.
