Doesn't it sound a lot like Niemandsland (1931)?

a.k.a. No Man's Land? http://www.imdb.com/title/tt0022204/reference

I saw this film... wow, it's been eleven years now, when I was ten, and I loved it, Then today I came across this German film that sounded very similar and coincidentally enough has the exact same English title. I just thought it was interesting and wondered if Denis Tanovic was influenced by the film in some way.
