The "Hollywood" series is the best documentary on Hollywood that I have ever seen. It presents silent movies in their correct speed and this makes a huge difference. It reveals that silent movies were not silent and in fact had orchestras of up to 100 musicians. It shows how different these films were,visual poems of music and picture. Silent films often had surprisingly good special effects as good as today's special effects. This series also tells us about the pitfalls and dangers of silents film production with extras sometimes getting killed. It reveals forgotten movie stars of the past and tells us about their lives and what befell them. This wonderful series deserves a DVD release as it is quite unique. My only regret is that they should have done a second series on the sound movies of the 1930's,which was Hollywood's greatest era.
