It's an hour-long interview with Rosenbaum on Welles. I too love the book, even though I have most of the articles already from when they were printed in magazines. Still, it's nice to have them in one place, and there are some new ones as well. I paricularly like "Orson Welles's Essay Films and Documentary Fictions", "Othello Goes Hollywood", "The Battle over Orson Welles", and "Orson Welles as Ideological Challenge", but they are all good writings.
For me, Rosenbaum is the finest living American film critic, and the finest living writer on Welles. He is only superceded by Bazin and Bessy (ah, those French) a list I might add to as soon as I finish reading the new book "Orson Welles at Work" by François Thomas and Jean-Piere Berthomé .
You might also want to check out Rosenbaum's other books as well: I have several, and they all challenge the usual assumptions about cinema today.
