You're telling me that Brody is the one who played the Ballade? Why don't they ever show his face and hands at the same time? They always show either hands or face, but not both!! And if he took a "crash course" and is able to learn the first Ballade, then find me that teacher right NOW!!!!!!!!
He didn't. I checked the end credits because I was thinking the same thing! It gives a pianist's name, anyway.
Brody took a crash course because Polanski insisted that the actor play. I've heard the first Ballade played much better, but you have to hand it Brody for learning it so quickly (and playing it at a below-freezing temperature).
Think the nocturne in C# was played by Spielmann ( a historical performance)?! and the others by a contemporary polish guy i forget who
