So what is foreign film on an English forum? Maybe everything outside of the USA? Everything not in English? Or the simple: everything outside the own country of every poster?
For German Films, I can recommend most films by Fritz Lang and with Til Schweiger.
As for UK films, I really enjoy the new BBC movies for "Sherlock" and "Jekyll". Other British Sherlock Holmes films can be very entertaining too, I recommend to see the ones with Peter Cushing or Jeremy Brett, like for example The Hound of the Baskervilles (1959 or 1988)
At Midnight I'll Take Your Soul (1964) is a nice horror film from Brazil. Not bad, too... Trollhunter (2010) from Norway is nice too...
I could make a world tour with such movies, I don't think that there is one country who never had a nice movie till now.
Oh and nearly forgot: The spanish version of the old Dracula movie. In original synchronisation: A must see ... some say it's better than the other film, with Bela Lugosi. I think they are equal.
Same goes for the movie: Incubus (1966), only watch in Esperanto with English subtitles. You won't regret it.
Incubus was made in the USA, but it seems more foreign than most foreign movies I saw yet.
