I remember standing in a line with my brother at a small shopping center with a large dome theater in Pleasant Hill, California. The line nearly rapped around the entire complex at the peak of the hype. This back when movies would be in theaters for more than a few weeks.
I also remember playing with all kinds of Star Wars action figures. I had a troop transport that fired plastic missles, an x-wing, and some other play sets. From the moment I saw the storm troopers I was in love that costume. For Halloween that year I dressed up a Luke Skywalker. The main reason was it was cheap costume to knock off. I would have been over the moon if there was a good storm trooper costume for kids back then. The only thing they had back then was those awrful plastic face masks with the cheap fabric thing that was supposed to simulate the look of the rest of the storm trooper outfit.
My brother had and still has the fake wood grain Atari 2600 and I remember playing The Empire Strikes Back for hours every day for like a month. It was repetitive and looked super blocky, but back then it was cool. I remember everyone going gah-gah over the vector graphics based Star Wars game where you did the Death Star run.
Alls I can say in Star Wars: A New Hope is what reminded media companies Sci-Fi fans have bucks to spend when the product is good. It was the beginning of sci-fi going mainstream.
I was lucky enough to visit Skywalker Ranch back in the 1990s and it was amazing. The money and technology Lucas has made was truly sparked by this movie. THX-1138 was an interesting, but kind of lacking sci-fi flick and thankfully American Grafifiti went over well or George Lucas may never had a chance to make this movie.
I can understand why some see the film as a little cheesy at times, but for 1977 this was mind blowing. For me, as a 5 year old, it took my breathe away. It might have been the first non-kiddie film I ever saw and I have been a sci-fi fan ever since.
