Director: Fritz Lang
Scarlet Street could easily have been written and directed by the Coen Brothers. The twists and turns, the characterizations, the black humor - I'd be shocked if they haven't seen this movie. It's a near-flawless noir masterpiece. The way in which the characters continually deceive one another while also deceiving the audience (and themselves) - it's brilliantly structured.
A year before Scarlet Street, Edward G. Robinson was in Double Indemnity, where he played Keyes, the logical and confident insurance man. Here he plays almost the very opposite - a put-upon low-level employee trapped in a loveless marriage. He's perfectly believable as both. The shots of him with an apron on, washing dishes, had to be more emasculating in the 1940s, but they look pretty bad today, too.
One problem is that the print of this film is rather awful - colors are muted and there are some strange cuts. Ah well, such is the cost of enjoying largely unloved films from long ago.
