The Groundhog Day theme has been repurposed more than once since it was released in 1993 with varying results. Its comedic properties are obvious, but that hasn’t stopped creators from using it in other genres like sci-fi and horror that, in some cases, have more dire consequences. One of the most surprising applications came in the unexpected slasher comedy, Happy Death Day, which employed the single-day-effect to create a fresh, entertaining narrative. But no one ever figured out what generated the loop… until now. In the immediate sequel, Happy Death Day 2U, it starts happening again — only this time we know why.
