Just a couple of ideas off the top of my head:
Locations - the iconography of The Third Man almost demands the Prater amusement park (and the ferris wheel therein); if you like something more historic, perhaps the palace at Schoenbrunn?
Characters - if I recall rightly, Pretty Poison (from Enemies: the International File) was an Austrian, described as one of the world's hottest fashion models; done for 3rd Ed, I think - kind of a cross between Claudia Schiffer and the space vampire from Lifeforce.
