 GEOG: When Marie goes to the KGB building in Kiev and Alexei finds  her there, persuading her to leave, the viewer can read a sign on  the building that says, in Cyrillic letters, "Ministerstvo na..."  This is a Bulgarian genitive construction, meaning "The Ministry  of..." The only Slavic languages that show the genitive case in this  fashion are Bulgarian and Macedonian. The genitive case is marked  differently in Russian and Ukrainian, which shows that the "KGB"  building could not actually have been in Kiev. This makes sense  because the film was partially shot in Bulgaria.
