Pretty Much Pop #80: Reliving Groundhog Day (and Palm Springs, Russian Doll, etc.)

Time looping, where a character is doomed to repeat the same day (or hour, or longer period) is a sci-fi trope dating back more than a century, but really entered American consciousness with the 1993 Bill Murray film Groundhog Day. Since then, and especially in the last five years, there have been numerous iterations of this idea in various genres from racial police-shooting drama to teen sex comedy. But do we need more of this? What are the philosophical ideas involved, and how do these change with tweaks to the scenario?

Mark, Erica, Brian, and returning guest Ken Gerber discuss not only the very recent and popular forays into this genre with Hulu’s Palm Springs and Netflix’s Russian Doll, but also touch on Edge of TomorrowRepeaters12:01 PMBefore I FallThe Fare, and episodes of The Twilight ZoneStar Trek: DiscoveryThe X-Files, and Rick & Morty.

There are of course other film and TV uses of this trope. For a relatively full list, you can see this wiki page listing time loop films and this other wiki page discussing literary antecedents. Also see the “Groundhog Day” Loop page on, and here’s a relevant reddit thread.

Watch the 12:01 PM 1990 short filmThis bonus episode of the 11.22.63 podcast had a great discussion of time loop media including the Ken Grimwood novel Replay and the short story “12:01 P.M.” and its sequels. You can read the 1941 Malcolm Jameson story “Doubled and Redoubled” online. As a forerunner to the time loop idea, check out the very short 1892 children’s story “Christmas Every Day” by William Dean Howells, where time does move forward with its consequences, but it’s always Christmas!

We talked a little about Happy Death Day with its costume designer in our ep. 38 and got into time travel more generally with Ken in ep. 22 and into “weird situations” in our Twilight Zone ep. 52.
