Please tell me any more information about this adaptation that you can remember. I don't speak French so I am not that familiar with this adaptation. How much did you listen to?
As far as specific scenes go, I am most interested in the first two chapters of the book (A Just Man, and The Fall) which deal with Bishop Myriel, Digne, and Jean Valjean from his early years up to Petit-Gervais. I like when an adaptation of these scenes are long/faithful/dramatic and includes minor scenes. For example, the 1982 USA radio adaptation includes five minutes which cover Bishop Myriel and the man he comforts before being guillotined. Another example is the 1944 Egypt film adaptation which includes the scene of Jean Valjean trying to sleep in a dog house in Digne and being scared off by the dog. In the book, what are your favorite parts of the first two chapters?
