Revealing mistake: In the scene in Salzburg train station, the trains that can be seen in the background are marked RENFE, which is the Spanish state-owned train operator. Also, when Fitzgerald looks at Roy through the window of the train, the station signs are "Salzburg Bahnhof", but only a few seconds later, when they are walking on the platform, the same signs are "Sevilla Santa Justa". This scene was actually shot in Seville train station.
