The Russia House" (1990) was among the earliest U.S. movies allowed to be filmed on location inside the Soviet Union, and it has a wonderful scene where Sean Connery and Klaus Maria Brandauer stroll into Leningrad's Palace Square before the Winter Palace. I fell in love with the romanticism of tsarist St. Petersburg after this scene:

Black Rain" (1989) by Ridley Scott had great Blade-Runneresque visuals of Osaka. I did not even realize till now that the now-demolished Kirin Plaza Osaka by architect Shin Takamatsu was seen in that film, and that I had seen one of my favorite buildings by one of my favorite architects long before I knew who or what either of them even were.

Of course, Osaka and Tokyo had long earlier been seen in model form in countless Godzilla movies and Dynaman tokusatsu shows.

Empire of the Sun" (1987) from Steven Spielberg was a fascinating recreation of 1941 art deco Shanghai, especially as it was the first U.S. production there since the 1940s and came just before the modern skyscraper boom of the 1990s forever changed the old treaty port skyline:

Such was the impact of reintroducing the romanticism of pre-war Shanghai to U.S. audiences that I recall Cathay Pacific at the time also using the movie's theme song, Welsh lullaby "Suo Gân," in some of its television advertising for cross-Pacific flights to Asia.

Amadeus" (1984) romantically inspired us with dreamy impressions of the charm and music of Baroque and Enlightenment Vienna under Joseph II, except it wasn't actually Vienna. Beautiful Prague with its larger collection of preserved Baroque buildings is the stand-in for the Austrian imperial capital.
