* DawsonCasting: Peter Billingsley (Ralphie) was 12-years-old playing a 9-year-old.
** Could also be the case for Darren [=McGavin=] as the Old Man. Intended to probably be in his early 40s, [=McGavin=] was 61 when the movie came out.
* {{Defictionalization}}:
** The Leg Lamp became a real product in 2003 when a fan of the film started manufacturing real lamps for sale. This then led to....
*** ...the fan using the money he made from his business to buy [[http://www.achristmasstoryhouse.com/ the house in Cleveland]] that was used for exterior shots of Ralphie's house. He later dropped another quarter-million dollars to gut the house and remodel it to look like the sets that were used for interior scenes. The house across the street has been turned into a museum and Leg Lamp giftshop.
** The specific BB Gun Ralphie wanted didn't exist; Jean Shephard had conflated several different models in his mind when he was writing the story. It exists now, though....
* DeletedScene: MGM mandated a 90 minute time limit. (The film still ran 94 minutes.) The Christmas Story House website [[http://www.achristmasstoryhouse.com/index.php/a-christmas-story-movie-facts/deleted-scenes/ has a page dedicated to these scenes]] including screenplay fragments of some of the scenes. The deleted scenes included:
** Alternate Openings
** Ralphie's [[MrImagination Mister Imagination]] fantasies of:
*** Miss Shields visiting Ralphie's parents at home to tell them how wonderful he is.
*** Ralphie saving ComicStrip/{{Flash Gordon}} from Ming the Merciless on the planet Mongo.
*** Ralphie saving Santa Claus from Black Bart.
* EnforcedMethodActing: Apparently no one told Melinda Dillon that the waiters in the Chinese restaurant were going to bring in a cooked duck with the head still attached. Or chop its head off moments later. Her reactions to both of those occurrences are genuine.
* HeyItsThatGuy:
** The Old Man is [[KolchakTheNightStalker Carl Kolchak]].
** And why isn't the mom [[Film/CloseEncountersOfTheThirdKind screaming "BAAAARRRRRRY!"]]??
** At the time the movie came out, some people were thinking "[[http://youtu.be/7-b_dRLrEvI Messy Marvin!]]" when they saw Ralphie.
* MarathonRunning: Every year, TBS runs the movie for twenty-four hours solid, beginning at 8 p.m. on Christmas Eve.
* TheRedStapler: You can now buy a leg lamp. The Red Ryder BB gun is an aversion, however; while now available, they were produced throughout the 30-odd-year gap between the end of the Red Ryder Franchise and this film's appearance.
** Not the particular model described in the film, however. [[note]]The Buck Jones air rifle has the compass and sundial in the stock, but none of the features of the Red Ryder. A special model was made for the movie to match Jean Shepherd's description in the story. While it may be ArtisticLicense, it is the configuration Shepherd claims to remember.[[/note]]
* VindicatedByCable: Only moderately successful at the box office when originally released, the film achieved CultClassic status in the late '80s thanks to TV and home video.
* WhatCouldHaveBeen: JackNicholson was apparently a fan of the short-stories, and really wanted to play Ralphie's Old Man (he was even willing to take a paycut if necessary![[note]]This is the same guy whose salary consumed the bulk of the budget for {{Film/Batman}}.[[/note]]). However, Jean Shepherd feared that the presence of such a high-profile actor in a supporting role would distract people from the main story.
** In hindsight, it's hard to see anyone other than Darren [=McGavin=] in that role.
** It would also be hard to see Nicholson swearing at the furnace being dubbed over by gibberish.
** Creator/WilWheaton was [[http://twitter.com/wilw/status/283386128072069122 considered for the role of Ralphie]].
