Here's the beginning of the city symphony film, which would include "Berlin: Symphony of a City" (1927) and "The Man with a Movie Camera" (1929). Although "Manhatta" doesn't contain the rapid rhythmic montage of some of the later city symphonies, it does have a sort of slower, poetic rhythm to it. It's discernible from a travelogue in that it has something to say about its city, other than it's a nice place to visit. The steady progression of images interloped with poetic intertitles taken from Walt Whitman produce the rhythm.
From the still photographer Paul Strand and the painter and still photographer Charles Sheeler, their view of Manhattan is, of course, modern. The shots are of skyscrapers and the inter-workings of the city. One is Strand's 1915 still photograph "Wall Street" come to motion. The composition, camera placement and observation of light and shadow are striking throughout the short film, and they are reflective of the work by the filmmakers in other media. Sheeler and Strand had already transplanted modern, abstract and formal ideas from painting into still photography and with "Manhatta" they similarly redirected film.
