It's Thanksgiving here in the U. The crew didn't know what was acting and what was reality when they watched it going on between them. Braden, he probably tried to make it look like he didn't mean to grab her breast. I can't believe I never noticed this egg I noticed this when I was watching it with some friends and we had to watch it like 5 times because it was so damn funny. Try searching in on-line gossip magazine archives, interviews with the co-stars [especially talkative Dave Prowse and the crew members], unauthorized biographs etc. Fisher's cup size was 32DD or 36Cwhich is well on display in the pictures of her rocking the costume without gaffer tape holding the intergalactic mammaries down.
Braden is Propably right.
Did George Lucas conceal Princess Leia's busty boobs in Return of the Jedi?
I haven't noticed this before but I'm not surprised at all - remember all the scenes with Fisher and Ford in episode5 on Hoth? I've read just about everything about Star Wars and have come across nothing referring to a relationship between Ford and Fisher on the set. Actually, nobody believed they were just friends during making the Star Wars movies. So, while folks bitch about George Lucas tinkering with his films by having Greedo shoot first, Han step on Jabba's tail, an extended dance number, and, well, all of the prequels, I'm going to bitch about him robbing me of Princess Leia's ample bosoms in that Slave Leia costume. As for whether it was on purpose or not, it looks like it was because he puts his hand on her shoulder and then on her breast. Han rushes to her side and grabs her. For this kind of information, official sources are useless.
