Chicago Reader review:
King Vidor's 1929 talkie was one of the first to take the microphone outdoors. Its reputation rests on its creative use of sound (notably in the chase finale), but the film is equally impressive for its use of space—the open fields that contrast, in their full, fluid dimensionality, with the purposefully flat, cramped interiors. A melodrama with an all-black cast, the film was socially advanced for its time, less so for ours.
Here (and above) is the trailer.
