The 1930-ties epoch was the time when totalitarian dictators roze to power. The support of peoples' masses was the saddest fact. I assume, personalities of Hitler, Stalin, Mussolini, etc. were not so important, they were just "iceberg peaks" of the processes that ruled the masses. But to achieve mass-support, they used propaganda techniques of the epoch.
I noticed some interesting fact: dictators look different on NBTV. When you watch them in historical chronicles, their manner to speak looks exaggerated, even funny and psychotic. But in NBTV quality, their manner appears more adequate and you understand why did they use exaggerated gestures.
Another phenomenon: NBTV can be frightening! It feels much more "live", opposed to the chronicles on regular TV. So when you watch some Nazi or Fascist speech, it feels like you are back in the 1930-ies...
Sorry for VERY LOW quality movies - neither camera seems to be able to shoot my Nipkow in focus and about of 50% detail seem to dissapear for this reason.
