It's fascinating to personally witness and remember how one particular movie put Hollywood -- and the world -- on it's proverbial "ear" and changed science fiction and pop culture forever.
On a personal note, my older sister was going to take then-12 year old me, along with her friends, to go see 'Star Wars' at a local theater about a month or so after its official opening. The day I was going to see it she called me and asked if I could give up my ticket to a much younger sibling of one of her friends, with the promise that she would take only me another time. Surprisingly, I said "yes", and toughed it out.
I don't recall if she kept that promise, but that was alright since my now-sainted Mom (God bless her) and I went to a local drive-in theatre that evening, which was about 5-7 minutes away. The feature that night was the western fantasy movie 'The White Buffalo', which I thought was pretty cool and still like. A couple of days later my sister brought me an official 'Star Wars' program that I must have read through a million or so times! Sure wish I still had it.
I remember being so fascinated (OK, obsessed) with anything 'Star Wars' that a junior high friend of mine and I paired-up and began to design spaceships in our spare time at school. Even to this day, I still say he had some very neat and imaginative designs, while mine tended to be more "stiff" and "linear", although now, when I think about it, I figure they were okay – for a 12-year old. That Christmas my brother and his now-sainted wife (God bless her) gave me the album "The Story of 'Star Wars'", narrated by the great actor Roscoe Lee Browne. I must have played it so many, many times, and sometimes I played it as inspiration while I drew spaceships.
It seemed like everything afterward that was science fiction was "a la 'Star Wars'", but that was fine because that meant there were many choices for this sci-fi fan, including the original ABC series 'Battlestar Galactica' in 1978, and the NBC series 'Buck Rogers in the 25th Century' a year after that. I was already a fan of 'Star Trek' and sci-fi in general, but, in some way, the original 'Star Wars' just "opened it up" for me and infinitely enhanced my view, perception, and appreciation of science fiction.
