I found it interesting how they always began a new section showing Elizabeth walking in the countryside and Darcy washing or otherwise being associated with water. It was so deliberately done it must have meant something but I'm not sure what it might be. Could Elizabeth's walking represent freedom, and a figurative breath of fresh air? And maybe Darcy's washing/water represents the gradual change (washing away) of his old outlook to see things in a new light. We do get a full immersion (Darcy swimming) right before he meets Elizabeth at Pemberly and that is when his behavior to Elizabeth and her relations changes completely.
Anyway, does anybody else have any ideas? Maybe I'm too obsessive, but when they do such an amazing job on a production like theirs it deserves some close scrutiny.
