Silent Night, Deadly Night is one of the more controversial horror films of the 1980s, blending festive cheer with pure terror. This cult favorite follows Billy, a young boy traumatized by witnessing his parents' murder at the hands of a man dressed as Santa Claus. Years later, his trauma returns when he's forced to wear a Santa suit at the toy store where he works — unleashing a violent, psychotic rampage during the Christmas season.
