Casting of Sony Pictures’ Da Vinci Code prequel Angels and Demons is shaping up quickly (see yesterday’s post about Ayelet Zurer). Ewan McGregor is in negotiations to take on the role of Camerlengo Carlo Ventresca, the Pope’s closest aide, who helps Robert Langdon (Tom Hanks) with his investigation. McGregor, who will be seen in Fox’s Deception, opening Friday, is currently filming I Love You Philip Morris opposite Jim Carrey. Angels and Demons is being directed by Ron Howard from a script by Akiva Goldsman. Brian Grazer and John Calley are producing. Filming is set to begin in Europe in June, with a May 2009 release date.
