OK, here goes, film school time - You can view DW Griffith's Birth of a Nation and his attempt at personal redemption, Intolerance, on Netflix. BOAN was arguably the first real, full size movie, and used every cinematic trick available in 1915 to create a vast, sweeping epic unlike anything ever seen by an audience. It also was arguably the most racist movie ever made, even by 1915 standards, so much so that it's downright laughable now, especially the white actors in blackface. After the film was banned in many places, Griffith, who feigned ignorance of his racism, tried to rehabilitate his reputation with the equally epic film Intolerance, which preached that intolerance was the downfall of many cultures. One of the strange ironies of those movies was that the huge, ancient world sets built for Intolerance on a Hollywood back lot were reconfigured, repainted and re-used in many other movies for a number of decades. As difficult as these two silents are, they are a foundation of movies as we know them, even today.
