Guys, here is a very useful reference website: Adolf Hitler and Third Reich Media.
There are several TV series including The World at War and Hitler's Bodyguard. There are many, many period newsreels covering many different facets of the era, Triumph of the Will is there along with many other propaganda films.
There are also hundreds of online books about almost everything connected to the TR. You can also listen to speeches, read about the ideology and Teutonic mythology, listen to the music of Wagner, watch the Goebbels family at home, the list goes on and on.
The quantity and diversity of information and reference material is too large for me to list so I'll stop here and let you explore the site.
