Can anyone who watches this movie ever erase from their mind the scene where Crawford finds out Palance and Grahame are plotting to kill her and goes stark, raving mad? It an Olympian display of overacting that has never been equalled: Crawford pulls at her hair, wildly darts her unfocused, bulging eyes, clamps her ears shut, pulls tight her grimacing mouth. A lunatic chimpanzee receiving electroshock couldn't do justice to Crawford's facial contortions here. I guess the reason that Crawford is such a fascinating screen presence to fans and nonfans alike is that she's a relentless masochist. In movie after movie, no matter what terrible fate befalls her, no matter how many times she is betrayed, it's nothing compared to the mental punishments she visits upon herself. The movie itself is serviceable but fairly ludicrous; there are glaring plot holes almost never seen in true film noir. The entire switched-identities ending is just about as bizarre as Crawford's performance.

The book was new and in perfect condition. The price was well below that of many competitors. It was sent in a timely manner. I would gladly buy from this company again.

Based faithfully on the book by Milan Kundera, a non-political Lothario doctor in Prague in 1968 comes to grips with two things in his life: his love for one woman and a commitment to the political uprising in his homeland. Because of the latter he is no longer allowed to practice medicine and is forced to live on a farm in poverty. His love for the woman, too, has been put to the test, yet he sticks with her, even though it means returning to his country after being given exile in France.The themes are intelligent and interesting, but the development is too slow: the movie is much too long at nearly 3 hours. Scenes seemed to be dragged out interminably, especially those in Paris as he weighs his conscience regarding his love and his homeland, and near the end on the farm. Because of this the movie as a whole seems to lack focus. But this is compensated for in the story's interest. The sex scenes are very sensual. Worth a watch.
