Social psychology - 2: The Wave

Yesterday I watched a German movie on Youtube called The Wave (original name: Die Welle), dubbed in Spanish. I can't find the movie with English subtitles, unfortunately.

 It's based on real events which took place in a high school in the US in 1967. This is what Wikipedia says about those events:

The Third Wave was a social experiment to demonstrate that even democratic societies are not immune to the appeal of fascism. It was undertaken by history teacher Ron Jones with sophomore high school students attending his "Contemporary World" history class as part of a study of Nazi Germany.

The following video is a documentary about Jones' experiment: Lesson Plan: Story of the Third Wave.
Fascinating stuff!
