However, one of the most significant differences between the two films is that Vertov seems to be praising the city and emphasizing the vitality and benefits of industry while Chambers seems much more critical of this busyness. It is almost like the city is no longer an economical and well-oiled machine, as in Vertov, but is chaotic and messy. For Chambers, the city has broken down and is no longer functional. This is made clearer by the juxtapositions with a slower paced and more peaceful natural environment. People are shown in fast succession and speedy movement.
Animals walk much slower and seem much more graceful.
The most evocative shot here is of a horse slowly walking from right to left as a car speeds by from left to right. The car has bypassed the horse-drawn carriage but has seemed to devolve in terms of gracefulness and beauty of form. However, just as I started thinking that I had figured out how to navigate through The Hart of London , Chambers switches to the second section which focuses mainly on nature. However, the soundtrack replaces the passing train with the rushing water hardly a peaceful or ordered sound. The camera slowly investigates several leaves but then begins to shake and move back and forth.
