Seven years ago, thousands of people descended upon Jeremy and Kristy Morris’ “Christmas House” in suburban Idaho, where holiday lights, a camel and a 35-member choir singing carols beckoned festive visitors. The holiday event, which served as a fundraiser for children with cancer, was so big that the couple decided that they needed a bigger house with more property for the following year’s festivities. U.K. based director Becky Read chronicles the ensuing neighborhood war and legal battle over the family’s 2015 holiday event – litigation is still pending appeal — in her Apple TV Plus documentary “Twas the Fight Before Christmas.”
