Your question merryowen really interests me.According to the IMDB which I use as my Bible, "NO BLADE OF GRASS "is an american film,It's obviously set in England and is based on an English authors novel,with an american influence in the cast,and an American director
"STRAW DOGS" according to the IMDB is a UK film set in england and based on a novel by a Scottish author,with an American influence in the cast and an American director.
Now here is where my knowledge ends and I am looking to my learned friends on this forum to supply us with the answers.I think the question should be what criterion(criteria ?) is used to establish the nationality of a film? I for all my love of film can honestly say I don't know but look forward to finding out (another part of my education on the Brit movie forum)
With regard to your prejudice Merryowen I'm not sure what your prejudice is,do you think they should both be American or British?

all the best
