I first saw Star Wars when it was broadcast on TV (on our 25" RCA color console TV, on CBS I believe) in '84 when I was 9 years old. I think this was the first time it was broadcast on regular TV, because it was a pretty big deal. Kids at school were talking about it about a week prior to its broadcast.
I was enthralled by it; it seemed so epic. It was an event, like The Wizard of Oz, but even better.
I'd been aware of the Star Wars movies since my earliest memories, and even had some of the toys (given to me by my neighbor who had "outgrown" them), including some action figures (Boba Fett, Luke Skywalker [orange flight suit], Darth Vader, a standard storm trooper, Hammerhead, and Greedo), Luke's landspeeder, a TIE fighter, an X-Wing, and the insanely awesome Millennium Falcon. All of those were built roughly to scale around the action figures, so they were pretty big, especially the Millennium Falcon.
So, between the toys I had and what I'd heard from other kids over the years, I knew what it was all about, but I'd never seen any of the movies. So seeing Star Wars for the first time after having wanted to see it for as long as I could remember, was a pretty big thing.
I didn't see another Star Wars movie until '87 when I was 12. My mother was going to be gone for the weekend, and she dropped my little sister and me off at our grandfather's house. He had a VCR (we didn't get one until Christmas of '88), and he said we could rent a couple of movies. So I rented Return of the Jedi and Star Trek IV (which was a new release at the time). I loved both of them, and watched them 3 or 4 times over the weekend.
For some reason, it was a while before I first saw The Empire Strikes Back, because even after we got a VCR and I could have easily rented it, for some reason I was under the impression that I'd already seen it. But, at some point in '89 I rented it, to watch it "again", and realized I'd never seen it. It too was amazing.
I remember talking about The Empire Strikes Back with my neighbor Jeff after watching it, telling him how great I thought it was, and how I'd just seen it for the first time despite thinking I'd already seen it, and how it was the movie where Luke first finds out that Darth Vader is his father. Jeff kind of scoffed and said, "It was obvious from what Obi-Wan Kenobi told Luke in the original Star Wars that Darth Vader was Luke's father." That claim is funny in hindsight, considering what I know now, but back then, everyone believed that George Lucas had 9 Star Wars movies all written and ready to go, right down to the last detail, before the first movie was even made.
