How to approach these topics?

[thenuttyprofessor]

My teacher has given some prompts for RW, that along the lines of how does Hitchcock do or achieve X?.
For example, "How does Hitchcock create a world of limitation and fear in Rear Window?"
How would we approach this? What sort of arguments to use?
I was thinking a much more visual approach
 - Limitation by restricting vision and setting to within Jefferies apartment
 - Limitation - Jeff's vulnerability and cocoon (maybe the entrapment fears he relays with marriage)
 - a world of fear through suspense
