I've noticed at least one mistake that still remains in Star Wars Episode IV, and possibly another one. In the Mos Eisley scene near the Cantina, I've noticed problems with shading direction, where for no reason the shade seems to change direction. And in the Death Star in the control room, right after Leia leads Luke, Han and Chewie into a trash compactor, a storm trooper still bangs his helmet on the door on his way in. I'm sure there's no way around it other than to completely redo that scene or possibly crop it to cut the open door out, but to the untrained eye, viewers barely even notice if even at all. Just thought I'd let you know.

So what. These aren't problems. They don't need to be fixed. In fact it would be wrong to fix them.
