Three Colors: Red (1994) dir. Krzysztof Kieslowski
Valentine is a young model living in Geneva. She has a boyfriend who lives in London, who seems to at the same time not care about her, but is also very possessive of her. One day while driving she hits a dog named Rita. She takes Rita to her owner Joseph Kern, who doesn't show much concern. Valentine ends up taking the dog to vet, and takes it home with her. A few days later Rita escapes and runs to back to Joseph. When Irene finds her, she learns that Joseph have been listening in on his neighbours conversations for years, learning all their secrets. Valentine is appaled but also intrigued about Joseph. While she threatens to reveal what he has done, she can't bring herself to do it. The two end up developing a friendship despite their many differences. In the background Irene's neighbour Antoine have quietly been living the life of Joseph with a 30 year delay.
Both Joseph and Valentine are lonely people. Joseph knows it, and uses his spying to get connected to people, although he doesn't seem interested in real connections with his neighbours. Valentine doesn't know it. She has a long distance boyfriend, but it seems like a one-sided relationship, where she lusts for him, but he doesn't for her. Without her boyfriend she doesn't appear to have any close relations. They find something in each other that they didn't know they were missing. It makes Joseph give up his spying and he turns himself into the police and tells his neighbours about what he has done. Valentine slowly starts to realise that she is loveable, and deserves better than what her boyfriend is giving her. But she still decides to go to London to see him at the end of the film. Platonic love like we see between Valentine and Joseph is rarely portrayed as beautifully in film as it is here. Irene Jacog and Jean-Louis Trintignant are both very good, and have a very good chemistry. They make very compelling friendship.
One of the most standout things about Red is the cinematography. Red is (obviously) a theme and almost constant presence in the film. Nothing about how Red is filmed is done by routine. Every colour, every angle, every composition has been conciously been picked, and nothing is done as you usually would. It makes for a very engaging viewing, and the cinematography tells as much of the story as the rest of the film.
Red is probably my favourite movie out of Three Colours movies. But I think my answer usually depends on whether or not Red or Blue is the most recent movie of the two that I have watched. They are both masterpieces in my opinion.
