Who would have guessed that the Communist Party Line would be delivered in song and dance? Those who love the movie musicals that were the crown jewels of Hollywood’s heyday will be surprised and delighted watching socialist movie musicals made behind the Iron Curtain. These films have everything our musical extravaganzas had—elaborate sets, unbelievable plots, intricate dance numbers—all in the service of the work ethic laced with only a minuscule of escapism. Delivered in a satisfying context of historic commentary and often in glorious color, propaganda was never so melodic.
