Geneva ? 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 U.S. extradition request hanging over him.

“It’s in fact very impressive. He is in the process of finishing at a distance the editing of his next film, which I understand will be in the official selection at the next Berlin Festival,” Levy said.

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 has to wear an electronic monitoring bracelet around his ankle to guard against his leaving the grounds of the chalet, but he is able to receive guests inside or outside the house, work on his films, make telephone calls and send e-mails as much as he likes.

Swiss authorities have said they will decide early next year whether to extradite Polanski to the U.S., where he is wanted in Los Angeles for sentencing for having sex in 1977 with a 13-year-old girl.

If Polanski breaks the conditions of his house arrest, the Swiss government would confiscate the $4.5 million bail he deposited.
