English newspapers and French/German signs?
All the clips from newspapers are in english (maybe this is only due to necessities of international filmmaking), but at the entrance of the tunnel you can see a wooden sign with something like "Cumieres-Weg Vorsicht einzuse...". It's hard to read.
Cumieres sounds french and there's a commune in north-eastern France with the name "Cumières".
"Weg" is german for "path" and "Vorsicht" is the german expression for "watch out".
Are we supposed to belief the film is set in France at the time where it was occupied by germans?
