The Woman in the Window (1944)

Directed by Fritz Lang

This is one of the best film noir that Fritz Lang directed.  Much better than the over-hyped Scarlet Street which had the same main cast of Ed G. Robinson, Joan Bennett and Dan Duryea.  A great example of the genre, it has all the identifiers associated with film noir and builds to a conversation piece of a conclusion.  Some love it some hate it (the ending that is).  Worth seeing so as to judge for yourself.
