A few of my favorite foreign films:
France - The Umbrellas Of Cherbourg, The Young Girls of Rochefort, Eyes Without A Face, The Soft Skin, all of Patrice Leconte's films, L'Appartement, Bob Le Flambeur and other Jean-Pierre Melville films, Sundays and Cybele, That Man From Rio - I could go on for days.
Japan - High and Low, The Bad Sleep Well, Stray Dog, Ikiru, Goyokin, and all of Ozu. Along with Gojira and many other sci-fi films, and many others.
Italy - The Bicycle Thief, Rififfi, Big Deal On Madonna Street, all of Sergio Leone, and many peplums, especially Hercules and Hercules Unchained.
England - all of Powell and Pressburger and way too many others to name - although I'll chime in during the day.
