The History of Green and Blue Screen in the Movies

While green screen has become ubiquitous for small (I have one in my garage for my videos), medium (PJTV has one in their L.A. studio) and gigantic productions (films like Sin City and 300), the basic effect that drives the concept dates back almost 80 years, to the early days of the talkies. A couple of years ago, the folks at Videomaker magazine produced a nice clip on the surprisingly long history of blue and green screen effects, going back to special effects wizard Linwood Dunn's pioneering efforts in the 1930s, all the way to the Matrix and other gigantic green and blue screen spectaculars.
