do they actually show in the film her doing this? Are those american troops? I know that the french helped out with the USA, but is this actually shown in the film? What is this scene actually? and are those really USA flags in the background?
Seems to be, Stars&Stripes based partly on Bremen flag (Germany :D ) ... and 1st developed in 1776. Read in Spiegel, that there seems to be a secene like this!
