I peaked around and found a newer version of your video on vimeo. I actually edited out a couple commercials and a trailer, but my friends really got into it.
And actually, he liked my presentation so much that he has asked me to teach it in his college courses!
I talked about the state of sci-fi in film and the depressing social events of the 70's but I'm looking for more. Does anyone know of any good resources that discuss how Star Wars changed the artistic and cultural landscape in '77?
