Edward G. Robinson gives the most subtle - and possibly the greatest - performance of his career in this, the most depressing film ever made. Such a devastating ending is hardly possible these days, and indeed wasn't supposed to have been in 1945. "Immoral, corrupt and tending to incite crime," they called it, "A Hollywood movie we can do without." Perhaps the subversive ending was Lang's answer to those who had criticised his 'cop-out' ending for 'The Woman In the Window' a year earlier. The other two leads - Duryea and Bennett - are brilliant as well, and all the actors make us feel in the end that no one has got what they deserved. 'Scarlet Street' has so many beautifully subtle touches in it that it really has to be seen several times in order to be fully appreciated: the parallel between Kitty and Chris' flower (his 'problems with perspective'); the expression that flashes over Kitty's face when Chris 'confesses' that he's a married man; the brief reference at the beginning to Chris's superstition, which will eventually bring about his psychological downfall. Like many Lang films, it deals with the concept of criminal justice, and is a clever, cruel and fascinating film - a little dated technically, but far ahead of its time, and one of the greatest and blackest film noirs from the forties. The climax is still one of the most chilling in film history - more frightening than most of the great horror films.
