Dear People of the World (formerly Dear Americans)

I bought a DVD of it last year. But I had seen the film many times before I bought that. 

The story of an Austrian woman who became a governess for seven children in von-Trappe family and was married to father of the children, Georg von-Trappe and the family became a singing group in 1938. But in the end, they decided to escape from Nazi-Occupied Austria. 

The story is based on the true family history. 

Songs in the film are all great and became famous. It seemed that is all about music. But the film described what happened in Austria during that time. Annexation of Austria by Nazi-Germany. Annexation was done peacefully and there were many local sympathisers like Rolfe, a boyfriend to the oldest daughter. 

Because recent movement in the world is becoming similar to that period, I watch this film from different angle. 

Why did people favor such authoritarian regime? What kind of atmosphere was that? 

Actually, people were less cautious than they should have been. 

That is what you can learn from the film. Good history lesson.
