This is one of the things that has always bugged me about all the updates of the OT over the years. If you are going to go to all the effort of adding to/changing the films, erase the old rotoscoping and fix it proper!
What? That’s what bugged you? I for one would hate to see those beautiful sabres erased. They would definitely look out of place in TFA, but in a 1970s movie? BEAUTIFUL
