Brazil at War was a 1943 propaganda documentary produced by the Office of War Information and the Coordinator of Inter-American Affairs.
The 9 minute long film trumps Brazils supposed "progressivness" under Vargas, noting that Rio de Janiero is a "modern city" know for its arts and culture, and that Brazils constitution allows freedom for its workers and social services. Then shots of the Brazilian Army and Navy are shown, and we are told that 3 million consripts are planned. A Brazilian Expeditionary Force did later see action in Italy.
After the segment on Brazils military, the economic contributions of Brazil are delved into, especially its rubber and crystal production.
