Groundhog Day might have stolen their idea from...
Another movie called Christmas Every Day (1987) - 6 years before Groundhog Day. I have yet to see that movie, but it's the same deal, one day, over and over again.
shareThe '87 Christmas Every Day, I've never seen, but Groundhog Day wasnt the first time I've heeard of this idea before.
maybe these things took it a bit to the extreme and had fun with it, but I had heard this idea somewhere before, doing something over and over.
