Hitchcock was a master film-maker and his comments on "cutting", "assembling" and "montage" are well worth listening too. The famous murder scene from Psycho is used as an example of montage. Hitchock goes on the explain how "the size of the image" can create shock in the scene where the detective is killed. Afterwards he demonstrates how cutting and the substitution of an image can change an audience's perception of a scene. Great for budding film-makers!
