Here are a couple of sites where you can buy DVDs of "public domain" movies and other hard to find old movies. Mostly.
I remember thinking in High School that I'd like to be rich enough to own prints of some of my favorite movies-- and I was thinking 16 MM. Now? Even old style DVDs can be upcast to 1080i--better resolution than the old theater screens ever had. you no longer have to be rich to have such things; you have to be pretty poor not to have them.
Amazing variety and quantity! I was looking at the DVD sales racks at Fry's the other day and realized that I probably didn't have long enough to live left to see every video on display there. A massive flood of information and entertainment, more than can be absorbed. More variety, more choices than I could have imagined being available 40 years ago.
I doubt I have anything new to say about all this, but every once in a while I break through the acclimatisation and wonder at it all. The once remarkable becomes mundane in such a short period of time that it becomes difficult to appreciate anything as remarkable. And yet so much is...
So. Take a minute. Recapture the wonder of it all.
And then let it be normal again, because it's impossible to get anything done when you're gasping in awe.
