Second time around for this B&W classic. Graham Greene wrote the novel and the adapation, Carol Reed directed. Joseph Cotton is a man-about-the-world Southerner who comes to post war Vienna at the behest of a bloke who he finds recently passed. There are also a Czech girl played by an Italian, two other blokes and the cops. So much effort is put into building up the mystery that nothing happens until Orson Welles arrives, and while the cat had the right idea I was left out in the cold. Many arty camera angles, some decent cinematography. Still #134 in the IMDB top-250.
Bosley Crowther at the time. Roger Ebert in 1996.
