Some Tallinn scenes were shot in Budapest, Hungary: The TV show playing in the background in Katarina's appartment can actually be heard speaking Hungarian. The Railway station at the end is Budapest Nyugati. The neon sign seen through the station's glazed façade reads "Libri", which is a Hungarian book store. The red and blue liveried train rolling stock is all Hungarian, with local operator MAV Start insignia clearly visible. Train geeks might even notice the uniquely and typically Hungarian V43 locomotive heading up Robert's train. That said, street signs, flags, license plates, indoor building signage and policemen's shirts were carefully disguised to be Estonian.
