I decided to take another look at some of the movies I watched back in the 80s, and this one stood out as one of the best films I've ever seen. After re-watching the film, I read the book, which is deeply philosophical and reflective. It's a very artistic film, an exploration of the human condition, of the ways that we experience life. The "unbearable lightness" is a kind of freedom that is joyful for some, but unbearable for others. Daniel Day Lewis gives a stunning performance as Tomas, a Czech doctor named Tomas who, though quite promiscuous, falls in love with a child-like woman named Tereza, played by the ebullient Juliette Binoche. Even though they get married. Tomas continues his affairs with women, especially Sabina, an artist with a fondness for wearing a bowler hat which she inherited. Tomas and Tereza have many adventures, including adopting a dog, and moving to Geneva. Tereza becomes a photographer and takes pictures of the Russian invasion of her country. Tereza must deal with Tomas's continual infidelity, and tries to come up with creative ways to cope with it, including offering to take part in his trysts. They seem at times happy, at times miserable, but always deeply engaged with each other and with life. It's a beautiful portrait of life in Czechoslovakia in the 1980s. If you love romantic films, art films or foreign films (it's an American film, technically, but based on a Czechoslovakian novel), you will definitely love this film.
