Changeling

Changeling is a 2008 film about mother and kid, about corruption in police at Los Angeles in 1930-1940, about greatest crime that was happened in XX century. It is based on real Wineville Chicken Coop Murders. 

I think that film is good as example of life in 30-40th years at previous century. There were a lot of old autos in a scenes, buildings, furniture and other. When I saw first a police officer dress uniform I remembered that in the computer game Mafia (first Mafia) uniform was the same. So it is really officer uniform)

Generally film was interesting, because we can see emotion of mother, who lost her son. But it is difficult for me to understand how people can make changeling lost son to stranger boy, then convince mother that it is really her son!
