reversed gender roles?

Did anyone else pick up on this? It started with the flowers that she gave to him (and that made me think back to a minute earlier to how he behaved: making himself pretty for her, and their telephone call where seems a bit dominant) and it continued on from there. I was especially impressed with the inflection in Portman's voice here, it really reminded me of a male's (she is normally quite soft spoken). And she was the active one - he was passive and gentle, in their exchange.

I thought this was very charming and interesting to see.

The nude scene kinda messes this up a bit though...
