This reference is extended to films which portray the struggles of the oppressed and the downtrodden often banded under the aegis of a 'Red flag' party.
Significant here is the ambiguity in the affiliation to the ideologies of specific political parties who commonly use red flags as symbols.
Erra Cinema regularly uses their literature and particularly songs penned or performed by them.
Due to the portrayal of the triumph of the proletarian collective over the hegemonic order these films are considered to be anti-establishment.
