I have been struggling with this for years. Very memorable film, 100% filmed on an undergound or tube station somewhere in central Europe. A black surreal comedy I think with subtitles. Possible vampires in there somewhere? A girl with angels wings goes up the escalator at the end. And there is a life threatening game of dares, race a tube train thro the tunnel to escape onto the platform. I saw this film at a film club abut five years ago. It would be brilliant to watch it again! Thanks Catherine
