2) when Vader is talking to Luke on the platform (after cutting Luke's hand off) you can see the shell of Vader's helmet moving in the wind.
Yeh, this has been mentioned. I'm not sure if i'll be doing anything with that because we do see that the hood part of the helmet is separate and it does help show just how windy it is up there.
This was Ady's response as I had mentioned the helmet thing a while back.
