Roman Polanski trying to finish his new film from jail

FRANKFURT, Germany (Hollywood Reporter) - Director Roman Polanski is continuing to work on his new film "The Ghost" from his jail cell in Switzerland and expects to deliver it on time before the end of the year.

"The film will be finished," Henning Molfenter, head of production at Studio Babelsberg and a co-producer on "The Ghost," told The Hollywood Reporter. "We will meet all our deadlines and all of our obligations with distributors."

Polanski had already delivered a rough cut of the film -- an adaptation of the Robert Harris best-seller, a political thriller -- before his September arrest in Zurich on a decades-old sex charge. Post-production has continued as the director continues to fight extradition to the United States.
