This is a propaganda film from the US Information Agency and is included with the DVD collection "Treasures from American Film Archives (2000)". When I say 'propaganda', I am not saying it's untrue or bad--but that the film is trying to sway your opinion in a political argument. In this case, the film is about the impact of the Berlin Wall on the people of this city. It illustrates not just the impact, but on ways the Berliners tried to overcome this divisive wall--and their spirit is inspiring as you see actual footage of folks escaping from the East to the West. It also shows the lengths to which the Soviet-backed government went to prevent these escapes--such as bricking in the windows of nearby buildings, razing buildings, using tear gas and mines and more.
As one of the other reviewers said, the film is not sensationalistic. It simply shows actual footage and narrates (in a rather subdued way) what is occurring. It's rather difficult to see all this without being affected--especially when you see footage of those killed trying to escape this prison-like city. As a result, it's very effective and makes its point quite well.
