All I know about Vienna and I heave learned from The Third Man, very definitely one of the greatest films ever.
And for my first two days there I learned little more, spending much of it inside the very splendid Grand Hotel (and everything you think a hotel called the Grand in Vienna might be, it is, all brocade, grand rooms, gold taps, kaffee and kuchen etc).
But the taxis I took through the wet and the grey showed a city straight out of Third Man country, all wrought iron balconies, smart shuttered shops, large dark front doors and spired sloping roofs. And the two hours I got to march round the centre were delightful, through the parks, the magnificent Burghof, past shops selling Loden and a million coffee shops, including the wonderful Demel where the obligatory sachertorte was purchased.
It must be time to see The Third Man again. The clip above is the scene where Orson Welles is finally seen for the first time, on a dark street corner as a pool of light falls on him briefly, and is possibly the greatest scene in cinema. Ever.
