Jar jar binks was originally going to be a bounty hunter who would eventually betray qui-gon Then they saw jar jar and.. ...yeah Han Solo was originally going to be an aquatic green alien (kinda like greedo) then he was gonna be a fat pirate with a beard, but they decided on the smuggler Han Solo we all know and love Mark hammil had to bang his head on yoda's hut 19 times before Lucas was content, Darth Vader In episode 5 actually tripped over a chord in the hoth base (lol) Mark hammil nor Carrie fisher knew that they were siblings (the BtS pic was hilarious, mark's face XD) The whole hoth scene was shot up in Norway And those rebel soldiers are Norwegian mountain rescuers, they did that part of the movie in agreement for Lucas to make a donation to Red Cross The scene with Han on his taun-tan was actually shit during a storm right outside the hotel they were staying at The line said by Luke "if he even exists" on degobah wasn't actually said, that was edited in, they darkened Luke's mouth but you can still see that his lips don't move haha I will add more if asked
