History Trivia / GroundhogDay

* CompletelyDifferentTitle:

** The movie is known as ''Un jour sans fin'' ("An endless day") in France.

** After Phil smashes the radio, ''it keeps playing "I Got You, Babe"''. However, that wasn't ''supposed'' to happen. It was such a wonderful, dark moment that Ramis left it in.

** Reportedly, Creator/HaroldRamis deliberately shot the film's various scenes in reverse order, because he knew from experience that Murry tends to start projects with enthusiasm, then grow increasingly irritable and impatient as their production drags on. Shooting the upbeat ending first and the snarky opening last allowed Murry's building frustration to carry over into Phil's recovery from jerkass-ness.

** In Spain, it's called "Atrapado en el tiempo" ("Trapped in Time").

* ReferencedBy: The film is referenced in ''Vietnam: An Epic Tragedy'' by Creator/MaxHastings, in a section about the American experience of combat:
-->This was a Groundhog Day conflict, in which contests for a portion of elephant grass, jungle or rice paddy were repeated not merely month after month but year upon year, with no Andie [=McDowell=] as prize in the last reel.

** Creator/AndieMacDowell asked Creator/HaroldRamis if she could use her natural South Carolina accent.

** And once you’ve figured that out, you’ll have no difficulty in guessing that the city road that gets closed off and forces the crew to turn around is actually in UsefulNotes/{{Chicago}} (Waukegan, to be exact), not Pittsburgh.
* CompletelyDifferentTitle:
** The Swedish title translates as "Monday the entire week". The movie, however, does not specify what day of the week it is supposed to be, and Groundhog Day (February 2) in 1993 was actually a Tuesday.

** The movie is known as ''Un jour sans fin'' ("an endless day") in France.
** The movie is titled ''Ricomincio Da Capo'' (I Begin Again From The Top) in Italy.
** In Spain, it's called "Atrapado en el tiempo" (Trapped in Time).

** As is usual for Bill Murray, when Rita slaps him, she really does hit him hard. Not surprising, since all of the abuse Murray suffered from Carol Kane in ''Film/{{Scrooged}}'' were real as well.

* NeverWorkWithChildrenOrAnimals: Creator/BillMurray was bitten by the groundhog twice during shooting. Murray had to have anti rabies injections because the bites were so severe.

* TheRedStapler: Since the film's release, the town of Punxatawney has now become a major tourist attraction.

* RoleReprise: Around 2019, Murray was asked to return to the role of Phil for a ''Groundhog Day'' Jeep ad to be filmed for the Super Bowl the following year, which also took place on Groundhog Day. Surprisingly, he said, "yes". The ad was once again filmed in Woodstock, and Stephen Tobolowsky and Brian-Doyle Murray also reprised their roles.

** The original script featured the explanation for the unending loop and its escape clause,[[note]]it involved a curse by an ex reading a "how to do magic" book[[/note]] but they found by [[DoingInTheWizard leaving it out]] made the film more magical.
** They flirted with the idea of a DarkerAndEdgier film, by taking full advantage of the no consequences mentality, (major cruelty, murder etc.), but they decided not to, realizing a more light-hearted comedy would appeal more to the general audience.

** Phil was written as a younger man, but this was changed when it was determined that the appropriate comic actors were all older.

* TroubledProduction: The musical went off fine during its run in London, but suffered several technical difficulties when it moved to Broadway, [[OnSetInjury plus lead star Andy Karl injuring his knee]] and having to get his costume refitted for a leg brace. This may help explain its brief run despite fantastic reviews.
