Joseph Cotton ("Holly") arrives in post war Vienna to meet up with his former school friend "Harry Lime" - only to discover that he was recently killed in an automobile accident. Without his promised job, he starts to chat with the friends of the dead man and swiftly spots some inconsistencies that lead him to become suspicious. He determines to try and find out just quite what happened. It becomes harder and harder for "Holly" to get straight answers - even from those whom he ought to be able to rely upon - "Maj. Calloway" (Trevor Howard) nor even "Anna" (Alida Valli), the dead man's lover - seem to be able (or willing to help). Gradually, also, he begins to suspect that he is being followed. Pinpricks of light from cigarettes in the shadows, shifting bodies hugging the dimly lit doorways - and he begins to realise that maybe his friend was not quite as scrupulous and honourable as he might have wished or appeared. Right from Anton Karas playing the distinctive zither theme at the top of the film we are treated to a wonderfully evocative adaptation of Graham Greene's mystery thriller and Carol Reed really does well with the pace of this too. We do make progress, but "Holly" has to work hard - as do we - for it, and his shady protagonists remain in the shadows, really effectively. This is a super story of trust, loyalty and greed that really is still as good now as it was 70 years ago.
