1. Louis Theroux - Louis And The Nazis (2003, 79min):

Louis Theroux, innocently looking explorer of social 
phenomena and fringe groups in the USA, this time ventures 
into the world of "White Pride/Separatism" (Neo-Nazism). 

He visits Tom Metzger, a former leading member of the 
Ku Kux Klan in California who feels himself more in 
tune now with the Skinhead movement and has ideas about 
becoming someone of international significance in the 
right-wing scene. 

Louis Theroux's second investigation explores the life 
of April Gaede and her two twin daughters Lynx and Lamb 
who form the "White Power" duo "Prussian Blue" (the 
lack of this chemical in the gas chambers of Nazi 
slaughter camps was explained by Holocaust deniers 
to be proof of their viewpoint that no industrial 
scale executions could have happened there). 

In the end Louis Theroux confronts Tom Metzger and 
April Gaede with his own take on their somewhat 
extraordinary view of the world.

2. Nazi Pop Twins - Prussian Blue (2007, 49min): 

Unlike "Louis and the Nazis" this documentary focuses 
exclusively on the Gaede family with April Gaede as 
the Arian activist mother and her daughters Lynx and 
Lamb at the center. This allows James Quinn to dig a 
little deeper than Theroux and reveal serious tensions 
in the family when it becomes more and more apparent 
that the pop duo does not share their mother's passion 
for openly expressing extremly divisive views on ethnic 
issues.
