The scene where she plays the concert is the best scene in the movie. Joan Fontaine totally sells it. I liked the cutaways to the wife, the son and the piano teacher. You can really ponder on what they were all thinking by their facial expressions-because she
was killing it on the piano. I think the emotions from the affair really helped her develop that polish she needed to be exceptional. Even her teacher had been impressed with her improvement in the dual practicing scene.
