Though Chopin was a true Polish patriot, Vidor highly romanticizes Chopin's patriotism in the film, which was produced duringWorld War II. He fictionalizes Chopin's relationship with Eisner (who did not really accompany him to Paris) and greatly distorts Chopin's relationship with Sand to produce a "good vs. evil" struggle for Chopin's soul between Eisner and Sand. The script occasionally sounds more like propaganda for wartime self-sacrifice over individualism than like the real story of Chopin's life.
Ayn Randwas sharply critical of the film, strongly taking the side of the George Sand character as against the Polish nationalist ones – a value judgement diametrically opposite to that taken by the film makers: "George Sand, according to the film, is evil because she provides a beautiful, private retreat where Chopin can live in peace and luxury, because she takes care of his every need, attends to his health, and urges him to forget the world and devote himself exclusively to the work of writing music, which he is desperately eager to do. The young Polish girl, according to the film, is good because she urges Chopin to drop the work that he loves and go out on a concert tour to collect money 'for the people', for a cause that is identified as national or revolutionary or both, and this is supposed to justify everything – so she demands that Chopin renounce his genius, sacrifice his composing and go out to entertain paying audiences – even though he hates concert playing, is ill with tuberculosis and has been warned by the doctors that the strain of a tour will kill him".
Victor Brown noted that "The breakup of George Sand's relationship with Chopin was for personal reasons completely different from those shown in the film - mainly Chopin's siding with Sand's estranged daughter against her mother. In fact, George Sand was an outspoken supporter of the Polish national cause in her own right, an allegiance which lasted long past the end of the relationship with Chopin. During theRevolution of 1848 in FranceGeorge Sand took part in a Polish solidarity demonstration held in Paris on May 15, 1848, calling for the French Army to sent to liberate Poland.
