I’d like to see that Zip disk lol! I still have my old drive from my Quadra. Just for the hell of it I did pull up LOA and Ep4 side by side. While an argument could be made for costuming, I still disagree in camera movements and shot selection - especially lens selections. Lean used telephotos for those sweeping wide shots (you can tell by the field compression and shallow depth of field) from very far away compared to the wide angle lenses that Lucas used (bit more barrel distortion and greater depth of field with a forced perspective) on Star Wars. This is also of course due to the fact Lean used 70mm equipment and Lucas shot on 35mm, but the same effect could have been achieved. About the only shot I could line up as a close match is the one of Luke watching the dual sunset and Lawrence on top of the train.
As far as influences, definitely there are a ton of call backs in Star Wars - everything from the opening scrolls to the story lines can be referenced from something, which to me makes Star Wars so special. Much like the afore mentioned Seven Samurai, all the individual elements existed before, but no one ever put them all together like that.
I still disagree on LOA and Star Wars based on my own technical observations, however.
