I am not sure that there has ever been a book about film quite like François Truffaut’s interviews with Alfred Hitchcock. Two masters discuss the craft of cinema. Truffaut listens carefully and gets Hitchcock to provide full disclosure of what he thinks is needed to make a film tick.
I have had the book for a long time but I have only just discovered that you can listen to the tapes online or download them here.
If you don’t speak French don’t worry. Wait for the introduction to end and you will hear Truffaut being translated into English and Hitchcock answering in English.
