One was research, one was thought provoking.
The Third Man - a huge classic. Scenes of Vienna, including the Riesenrad (giant wheel). I'll be staying near the Prater, so it will be in my "backyard". Fabulous movie, very atmospheric.
Don't watch this if you're squeamish - not a "nice" movie at all, but based on research about the quality of meat, the immigrant labour force, the American dream.
