You’d expect a film with a title like Hitler’s Children (1943) to be an exploitation picture, not a prestige production and you wouldn’t be wrong in most respects. But this sensationalistic melodrama about a Nazi youth and his American girlfriend struck a resonant chord with audiences of its era, making it the highest grossing film of all time for RKO Studios, surpassing even the box office receipts of King Kong (1933) and Top Hat (1935).
