Spain in Flames
Spain in Flames is a 1937 compilation film made by Helen van Dongen during the Spanish Civil War. Hal Erickson has written that the film ... is remarkable in its willingness to offer both sides of the conflict though its sympathies are firmly with the Loyalists. The film consists of two parts. The first, The Fight for Freedom, was based on film footage from a Spanish government documentary Spain and the Fight for Freedom.
