Siegfried Line

His documentary and narrative films directly confronted the brutal reality of the Siegfried Line campaign, particularly in 'The Big Red One' which depicts American infantry combat in Europe.

His examinations of German identity, militarism, and the psychological scars of WWII provide critical retrospective engagement with German defensive positions and national trauma from the Nazi era.
