Fritz Lang's 'M' is, in my opinion, one of the greatest films ever made. The craft and artistry that is on display at such an early stage of film (1931) is bewildering and as fresh now as 88 years ago; but to think is wasn't that well received at first (isn't that always the way Orson?)
I'm loving these BFI books, but this one is of a higher standard - the research and academic understanding and appreciation of this film, where and when it came from, is of the highest order, whilst maintaining it's accessibility for the reader. It uncovers and presents a 'lost' scene and also looks at the lesser known American remake of 1951, from which, when referring to the original, we get the superb quote:
"It is a picture which I do not believe could, under any circumstances, have been made in Hollywood...Nevertheless, Hollywood will make better pictures seeing this one".
