This is not my first viewing of Rear Window. It is a great movie, and probably my favorite work by Alfred Hitchcock. The best thing about Rear Window is its staginess. It could be a stage play. The movie even opens and closes with the raising and lowering of curtains, window curtains.
This is my first time watching it in HD though and it was really great to see it that way. We have a projector at home instead of a traditional TV. So it was great to see this large and in high definition.
