An entire movie's plot seen from the windows of the Hadley house
I was chuckling over how many times something happened in the movie and we cut to someone observing the scene from one of the houses windows. And the insert shot of the actor in the window always look completley phony... thus, easier and less expensive to shoot:
Stack arrives home drunk for the climax (pick your favorite window, it's observed by everybody)
Butler retrieves funeral wreath (Bacall)
Mitch and Lucy drive off (Malone and Stack)
