Labyrinth of Lies is a 2014 German film about the Frankfurt Auschwitz trials that took place between 1963 and 1965. What distinguished the Frankfurt trails from all the other trials was that they were based on German law and because they happened 20+ years after the war, they were limited to murder charges. Several Nazis had been tried previously but they were convicted under international law and occurred right after the war.
The film begins in 1958 as a young prosecutor Johann Radmann (marvelously played by Alexander Fehling) is attracted to the case by a reporter (Andre Szymanski), and given support by the federal Attorney General (Gert Voss who is simply riveting). They must work against the denials, cover-ups and vested interests that try to keep the issue quiet.
The film gives you a real feel of the late 50s, and the photography and music support an excellent cast who do wonderful work. In a film about the holocaust, there is a tendency to shock, but director Giulio Ricciarelli skillfully shows that less is more.
There are some places where the film seems more like a docudrama, and some issues (e.g., Radmann's relationship with his mother) are only hinted at. But overall it's an excellent film, and while it may not be an equivalent to "Judgment at Nuremberg", it is well worth viewing.
