Notorious

Alfred Hitchcock - 1946
I can only agree with all the nice things others have said about this film; it's terrific, executed perfectly, tight.
It is perhaps one of the more (early?) 'objective' Hitchcock mis-en-scene, that is , two shots, more space given to the characters and so on (Cary Grant). There are, as always, decisions in the staging, subtelties or rather creative decisions, that are suited to each scene; for example, remianing tight on the embrace for an incredibly long time (with that domestic dialogue!), keeping Grant sitting at certain times. There is often an SRS where we get the 'real' action, or rather suspense, of the scene, rather than the one the dialogue seems to think.
There are individually great moves here, often on the stairs. Their is a great theme of 'the greatest to the smallest'; the massive crane to the key is the perfect example. In fact, that whole sequence, with the checks, checker piece humans, on the floor is a compostional wonder (also notice the same hall's use in an extreme long shot for when Bergman collapses).
The suspense here is created incredibly economically, often by having two sets of people in supposed dialogue, but in fact at cross purposes. The fact that the great exciting finale is somebody being taken down a set of stairs. Also, we see some humour, though this isn't one of the masters' more obviously funny ones; the faintly ridiculous mushing about with sand.
