Mr. Arkadin (first released in Spain, 1955), known in Britain as Confidential Report, is a French-Spanish-Swiss coproduction film, written and directed by Orson Welles and shot in several Spanish locations, including Costa Brava, Segovia, Valladolid and Madrid. Filming took place throughout Europe in 1954, and scenes shot outside Spain include locations in London, Munich, Paris, the French Riviera, and the Chateau de Chillon in Switzerland.
Japanese film director Shinji Aoyama listed Confidential Report as one of the Greatest Films of All Time in 2012. He said, "No other movie is destructive as Confidential Report, which gives me different emotions every time I see it. Achieving this kind of indetermination in a film is the highest goal that I always hope for, but can never achieve."
