Very cool!

Ah, it's all in an around Semur (picture below)! The  Château de Marigny-le-Cahouët was the girl's house, next to the bridge of the D119k in Braux was the fishing scene. I could have visited Semur-en-Auxois when I was in Dijon (along with nearby Flavigny-sur-Ozerain, where "Chocolat" was filmed).

ps: it was one of my favourite movies when I was a teenager, but I haven't seen it again since I was a teenager :-)

I have just seen it for the first time since then :-)
