Happy Death Day 2U

Trivia: Spoilers. In the end, Dr. Butler and his wife Stephanie are revealed to be the killers. They were actually the killers in the original script for the first film, but the ending was changed several times until the final version seen in theaters with Lori being the killer. The original idea was recycled into this film, since the dimension-hopping angle of the story allowed the presence of a new version of the killer.

Trivia: The wood-chipper Lori leaps into is labeled "Biff's Tree Removal." This is a reference to the "Back to the Future" film series, which features a prominent character named Biff. The "Back to the Future" movies were one of the inspirations for the film.
