He's got a collection of essays on writing called The Curtain. I started reading it about a month ago, and wound up putting it down again. I'm finding it hard to stick with anything lately. Was shocked that even Kundera couldn't keep me focused, but I just lost interest.
I think my favorite of his is Immortality, but I love them all.
I loved the character of Tereza in Unbearable Lightness - she saw herself as weak, but I thought she had so much guts. I loved Juliette Binoche in the film version; she was perfect for the role. As for Tomas, I saw parallels between him and Sabina; they seemed to be the male and female version of the same type of person...just playing it out in slightly different ways. I should read that book again.
Kundera supposedly hated the film, and resolved to never again write a novel that could ever be worked into a screenplay. I loved it, but maybe I'm strange. I remember loaning it to a female friend, and she was completely shocked that a woman could like the film. I seem to be good at shocking people sometimes.
