Hi Mrrzy,
FOREIGN CORRESPONDENT is one of my favorites. Now video - it was UN-available for quite a while which may account for it being less well known than the late British productions, and the American films. A Walter Wanger Production, ownership and distribution rights were in question for a while. IIRC a VHS tape from a small company was available, but A good print was released on DVD by Warner some years back. Last year CRITERION released a remastered version on DVD and BLU-RAY with some interesting extras.
Best wishes, Thomas.
