Prada — the Devil’s favorite fashion brand, as the film and book would have it — is launching a giant multi-disciplinary arts complex on the edge of Milan that it hopes will attract tens of thousands of visitors a year. The inaugural program features an exhibition on classical sculpture and a special appearance by Polish-born filmmaker Roman Polanski, who will present a documentary and a series of film screenings looking back on directors who influenced him most. A mixed program of art exhibitions, film screenings and philosophy projects is planned.
