Public domain films on the internet....

[Jason Gray]

Thought I would look on one of my favourite sites, The
Internet Archive, (www.archive.org) for that NYC subway
film. I didn't find it, but was reminded of this film "Our
Enemy:  The Japanese". The footage of 1943 Japan (mainly
Tokyo) is fascinating. The film is massively didactic,
disturbing and beyond racist, but you can't take your eyes
off it.
