Sixty years on from the release of The Third Man, tour guide Dr Brigitte Timmermann uncovers Graham Greene's Vienna and takes us in the footsteps of his film. Walking through the city, she tells the stories that have fascinated generations of film buffs, from Soviet master spy Kim Philby's role in the film to tales of Sir Carol Reed and Graham Greene's late night visits to Vienna's seediest bars. With the help of fellow devotees, Brigitte explores Vienna's hidden history and examines why The Third Man has remained largely unpopular in the place which inspired it.
