Fresh Air interview with Walter Murch (sadly, sans transcript or audio). The program description from the NPR web site:

Film editor and sound designer WALTER MURCH. He has re-edited Orson Well's 1958 film "Touch of Evil." At the time of the film's initial release the studio remixed the film to Well's displeasure. He fired off a letter with suggested changes. With those notes as their guide, MURCH and re-edit producer Rick Schmidlin have reconstructed the film to Well's intentions. Some of the other films he's edited and/or mixed are "The Conversation," "American Graffiti," "Apocalypse Now," "The Godfather (II, and III)"and "The English Patient." He's also written a book about his work, "In the Blink of An Eye: A Perspective on Film Editing," (Silman-James Press 1996) (This originally aired 4/15/96)

"Who Are You Calling Genius?: It's time to retire the term," by Ron Rosenbaum:

From "The Battle Over Citizen Kane" episode of American Experience:

NARRATOR: Kane was also forty years ahead of its time in its portrayal, not of Hearst, but of the man who made it. It was Welles who lived out his life in isolation.

ROBERT WISE: Well, I thought often afterwards--only in recent years when I saw the film again two or three years ago when they had the fiftieth anniversary, and I suddenly thought to myself, well, Orson was doing an autobiographical film and didn't realize it, because it's rather much the same, you know. You start here, and you have a big rise and tremendous prominence and fame and success and whatnot, and then tail off and tail off and tail off. And at least the arc of the two lives were very much the same.

...

WELLES: ...I have wasted the greater part of my life looking for money and trying to get along, trying to make my work from this terribly expensive paintbox, which is a movie. And I've spent too much energy on things that have nothing to do with making a movie. It's about two percent moviemaking and ninety-eight percent hustling. It's no way to spend a life.
