Another Thin Man is at times quite funny but is less a comedy than a screwball mystery, which is to say it is a nice little atmospheric whodunit with laughs, populated by an assortment of urban types and set largely on a Long Island estate.
The film is well-paced and has just a hint of the supernatural, which gives it at times an eerie flavor. Photographically it is darker in tone than its jollier predecessors despite the oftentimes comical goings-on.
The occasionally somber mood of the picture perhaps anticipates the coming of the world war, as there is an undercurrent of urgency and dread in the way its story is told that seems to come from outside the movie itself.
William Powell and Myrna Loy prove themselves once again to be the Fred and Ginger of detective movies.
