Also the formerly banned documentary style movie Native Land narrated by famous African American communist singer and actor Paul Robeson is pretty based. McCarthyists immediately banned it and all major media outlets in the us denounced it as propaganda.
Land and Freedom is a British film produced in England by an English director under a then-British production company. It is a super based movie about the anti-fascist struggle by the Spanish Republican forces and it glorifies leftist unity, Communism, and United anti fascism. All of the major characters are either communists or anarchists, the main protagonist being an English Communist, and there is literally a scene where they sing L’Internationale in Spanish.
Love that rendition.
