Groundhog Day is one of the greatest timewarp movies ever, but the TV-movie version, 12:01, is also great in its own way. Someone recklessly fires a particle accelerator, causing a "time bounce" that only Jonathan Silverman remembers.

You have to love Helen "Supergirl" Slater as a Capenters-loving scientist, and Martin Landau as an evil mad genius. You just have to. [IMDB]
