This is an amazing documentary film by Peter Jackson, who made the Lord of the Rings trilogy. He had access to a lot of 100-year-old film that he restored and colorized so that it looked like it had been made yesterday. After the movie, Jackson spent about a half hour telling/showing how the film was restored. The original film lacked sound, but in some cases lip readers were able to tell what was being said and it was dubbed in.
All in all, this was a better movie than most of the stuff up for Academy Awards.
