Orson Welles’s Mr. Arkadin (a.k.a. Confidential Report) is one of cinema’s great mysteries. How did a globetrotting narrative of espionage, amnesia, and backstabbing come to be itself marked by these qualities? In the film, small-time American smuggler Guy van Stratten is hired by elusive billionaire Gregory Arkadin to investigate the tycoon’s past. What follows is a dizzying descent into the Cold War landscape of a Europe trying to erase its history. In making the film, Welles was ultimately banned from the editing room by producer Louis Dolivet. As a result, many versions exist, none of them definitive. The Criterion Collection is proud to collect the many faces of Mr. Arkadin into one box for the first time—from the story’s beginnings in radio to the novel published under Welles’s name to an all-new "comprehensive version" of the film.
