Just saw “Violent Night” yesterday and the IMDB guest reviewers correctly say it’s Santa Claus caught up in a John McClain scenario. It was pretty good but dragged down with unnecessary cursing like too many other modern productions.
The matriarch of the family was played by Beverly DiAngelo - Mrs. Griswold of “Christmas Vacation” herself.
Before the mental deterioration set in Comedy Central gave Bruce Willis a roast where he made it clear that he doesn’t consider “Die Hard” a Christmas movie. I’d say that was the first sign of his illness.
