Rear Window is a movie with half it scenes and shots set in the ‘first person POV.’ L.B. Jeffries being confined to just a wheelchair has a lot to do with reason behind the ‘first person POV.’ Being cooped up in his house for six weeks straight with a broken leg has left his mind to wander, and become a “peeping tom,” hence that POV. Any chance he gets he is looking into someone else’s life, through his binoculars or his long lens. He even gives nicknames to the people he watches other than Thorwald, such as Ms. Lonely Heart, or Miss Torso. This is typical behaviour in voyeurism, keeping the scenarios of another person’s life impersonal. For some reason though, it was different for Thorwald. Jeffries watched him like a hawk, and had his mind start to run, shooting off as many possibilities as he could as to what happened to Mrs. Thorwald. The whole movie takes place across a long hot, summer week, the week that is supposed to Jeffries last in the cast, until his suspicions of Thorwald turn out to actually be true. I think that Mr. Thorwald was unhappy with his wife, and with the temperature getting so high, so were tempers, which led to wifes ultimate demise.
In the beginning of the movie Jeffries was not sure if he was gonna stay together with Lisa. In fact he was ready to let her leave him. But as their imaginations run wild, and fiction turns into reality, Jeffries falls back in love with her. She scales across the side of Thorwald’s apartment; maybe to prove a point to Jeffries that she can go on those dangerous long and non-dainty trips with him, or maybe she herself was also so caught up in this murder mystery that happened across the courtyard. They end up together, a typical romance trope, now with two broken, and two people in a one person apartment.
