Haha - the creators aren't the smartest ones

In film, all kinds of places are used to portray all kinds of other places all the time. The point is that the supposed jurisdiction of location (for example, Warsaw, Poland) might not like what is depicted as taking place there and deny permission for shooting. Hence, Bucharest, Romania, for example, is used. Or budgetary constraints or convenience are controlling. The TV show "NYPD Blue," as an instance, was filmed in Los Angeles, though set in New York City. When you show a very noted landmark or geographical feature that's out of place, however, it can be a howler, as in the Jackie Chan movie "Rumble in the Bronx," which was filmed in Vancouver, British Columbia, and shows snow-capped mountains in the background of "da Bronx"!

Unless someone moved the Chain Bridge - and the Danube River - to Romania, that early shot is indeed of Budapest. (Yes, there are other scenes filmed in Romania.)

Looking for something to criticize? I look for something entertaining or interesting. I know a fiction film is not a documentary.
