I hate to say it, but the cut scenes are the most irritating Han Solo performance in the original trilogy with Harrison Ford repeatedly yelling “come on!!” at everyone as they move through the bunker. This is usually directed at Chewie (something he did, word for word, in Empire in the scenes in the Falcon just prior to entering the asteroid field).
So, this came up in the ANH thread and I remembered seeing designs on the mystery flash hider.
It's lines... similar to like.. AK skyle flash hiders with a short cone and some flanges, and then the cylindrical part has ridges along it. What else do you see?
