I love how the Golden Gate bridge points to Kim Novak like a dagger. The clouds above her head reflects her emotional turmoil.
Strangers on a train
Went a little looser on this - I haven't seen North by Northwest in a while but just by looking at the image I know it was a moment in the film where Carey Grant felt trapped or conflicted just by the design of the shot. Love how the shadows of trees point back to him. I think this is an instance of Hitchcock painting shadows as they didn't make sense based on the light source.
