You can see many Humgarian buildings, architecture, because we have a large studio "village" working on many movies and TV series (thanks to the Hungarian producer in Hollywood, the late Andy Vajna). Some of these movies' scenes was captured in Hungary from Will Smith's "Gemini men" to the new TV series "The Day of the Jackal". But I could mention Katy Perry's clip "Dark Horse" too.
Anyway these architectures seeing in person is another feeling. Good luck if you will have any opportunity to visit Hungary.
