Overview:Documentary looking at Orson Welles and the production of the film CITIZEN KANE fifty years ago, considering the furore that accompanied it and the real life press baron William Randolph Hearst upon whom Kane is based, and his efforts to halt the film, destroy the negative and persecution of people involved with its production and showing. It includes BBC interviews with Welles made in 1960 and 1982, and film historian Robert Carringer looks at the scenes that never made it to the screen. American film critic Pauline Kael also analyses the film's enduring appeal. Extracts from "The RKO Story" (producer: Rosemary Wilton) and "Yesterday's Whitness" (producers: Christopher Cook and Stephen Peet).
