The UK art-mongers naturally picked a British film as the top film of the 1940s (read the list to find out, but many of you will instantly guess which one it is...) and its selection of noir does include some international films...but you decide if their placement of American noir within this list makes sense.
All in all, an interesting enough attempt that it might have been interesting to watch the authors/editors wrangle about what went where on the list...
