Adam B. Vary Senior Entertainment Writer SPOILER ALERT: This story discusses major plot points, including the ending, of “Abigail,” currently playing in theaters. The vampire thriller “Abigail” originated as a modern-day update of the classic horror film “Dracula’s Daughter.” But by the time the filmmaking trio Radio Silence — producer Chad Villella and directors Matt Bettinelli-Olpin and Tyler Gillett — began production on “Abigail” in Ireland in the spring of 2023, the movie had virtually no connection to the 1936 Universal picture.
