“The Wedding Day,” by acclaimed director Wojciech Smarzowski, tackles the 1941 Jedwabne pogrom, during which Polish villagers tortured and murdered hundreds of Jewish neighbors. The story is set at a wedding celebration in a small town in North-Eastern Poland, and moves between past and present, with repressed memories of past violent events resurfacing in the present. In “The Wedding Day,” Smarzowski offers a stringent critique of current-day nationalism and the politics of denial in Poland.
