I am using borrowed footage from various archival sites for the final Dominartist film. Here are some links to very cool footage that has inspired me and that I am using in part to get my messages over.
Original uploads by War Aesthetics on Youtube.

Subtitles and original video descriptions are available in each video's folder where applicable.
Files with the .mkv extension can be viewed using VLC media player, which is free.
