Orson Welles was the genius who changed the face of cinema with his 1941 directorial debut, Citizen Kane, and who became one of the key artistic figures of the 20th century – a great raconteur as well as a great artist, and larger than life in every sense. In 1982, Welles was the focus of a two-part BBC documentary that told the story of his life, The Orson Welles Story, and here, its producer, Alan Yentob, looks back on his encounters with this giant of a man, telling the tale of their behind-the-scenes dealings and explaining why he believes Welles’s legacy is still significant today and why he will always deserve his reputation as a genius of cinema.
