Rear Window (1954) directed by Alfred Hitchcock. Photographer LB Jeffries (James Stewart) is wheelchair bound for the next six weeks. He has nothing to do but to spy on his neighbors with his telescope. One night, he witnesses his neighbor a costumes jewelry salesman Lars Thorwald (Raymond Burr) up at 3:00 am in the morning. He's walking out in the rain and in the morning he's disposing of his handsaws and knives. His wife Emma Thorwald is no longer in the apartment. Jeffries suspects Lars killed his wife. His friend detective Thomas Doyle is skeptical because there's no body and the evidence is very slim but his girlfriend Lisa Carol Fremont (Grace Kelly) and his nurse Stella start to believe Jeffries is onto something.
I came away sympathizing with Lars because he was getting verbally insulted, day after day, by his stupid wife. When a person gets provoked as often as Thorwald was, he's gonna snap.
