Continuity mistake: When Raphie's mother is working on the turkey on Christmas morning, there is a jar of pickles on the table next to the turkey. In the next scene the mother is coming up from the basement carrying a jar of pickles and places them on the table in the same place.
Continuity mistake: On Christmas morning when they open presents, the sleeves on the mother's robe move back and forth between rolled up and rolled down.
Visible crew/equipment: As the buck teeth are being handed out at the beginning of the classroom scene, the camera pans to follow Miss Shields and you can very briefly see the shadow of the boom microphone on the wall at the top of the screen.
Continuity mistake: In the playground scene when Flick first sticks his tongue to the flagpole, the street in the background has been snowplowed. The kids all go back in to the classroom without Flick. When the teacher asks "Where's Flick?", and looks out the window and sees him at the pole, the same street in the back ground has not been plowed.
Continuity mistake: When the "old man" first puts the lamp on the edge of the box there is no light fixture on which to place the shade. He then returns the lamp to the box and when he brings it out, there is a place to put the shade. Also as he hands it to the mother and then takes it back to put it on the table, there is no electrical cord visible. However, just before he sets it down on the table you can see a cord in his left hand.
Continuity mistake: In the second kitchen scene after Ralphie sits, the camera looks at the cellar door, where you hear the old man cussing up a "cloud of profanity that still hangs over Lake Michigan." The damper controls are sitting top to the left, bottom to the right. After the "accident" with the lamp, dad comes upstairs. The controls are now reversed, top to the right, bottom to the left.
Continuity mistake: When Randy is getting dressed for school, his mittens keep appearing and disappearing from his hands.
Continuity mistake: When Santa pushes Ralphie down the slide with his foot, Santa is actually seated too far away from the slide for his foot to have reached Ralphie's face. In all the wide shots of the scene (especially the very last one as the family leaves the store), you can see that Santa's chair is placed too far away from the entrance of the slide for his foot to have reached the sizable distance to Ralphie's face. But in the tighter P.O.V. shots where Santa is talking to Ralphie just before he gives him the boot, you can see that Santa's chair has been moved over and placed directly in front of the slide so that he can easily reach Ralphie's face. Even better, just as the Elf places Ralphie in Santa's lap, there is a 360 degree panoramic shot that shows just how far away the slide is from Santa's foot.
Visible crew/equipment: On Christmas morning when Ralphie opens up the bunny suit, you can see stage lights in his glasses.
Continuity mistake: When Ralphie's father is sitting in the chair reading the funnies (before the dogs ruin the turkey), there is a small gold lampshade sitting on the table next to him. In the first shot, there is a Christmas bow on it. In the following shot, the bow has disappeared.
Continuity mistake: When the dogs steal the turkey and wreck the kitchen, there's a scene of the table broken and no pot holder is on the table. In the next scene, there is a pot holder sitting on the broken table.
Continuity mistake: During dinner Randy has been eating like a "piggie" and his face is covered with food, when the doorbell rings. As he gets up to answer the door he looks to left and his face is clean but then as they go to the door there are mashed potatoes on his face again.
Continuity mistake: When Melinda Dillon breaks the lamp, it is broken into many pieces, but when Darren McGavin is gluing it back together it is now in much fewer and bigger broken pieces. Obviously different broken lamps were used.
Continuity mistake: As Ms. Shields lectures the children on what happened to Flick, the phrase "the quick brown fox jumps over the lazy dog" is written on the blackboard behind her. But when she is done lecturing them, she turns around to reveal "A Theme: What I Want for Christmas" written there instead.
Continuity mistake: In the Chinese restaurant scene, the opening shot through the window shows the worker directing the music with Ralphie to his right and he is facing the singers. In the next shot, the same worker is behind Ralphie and the singers are to his right.
Continuity mistake: After Melinda Dillon breaks the leg lamp, she holds the broken leg in her arms in a pile of three separate pieces. After Darren McGavin asks "What broke?", the 'leg' magically heals itself into one single, straight, yet loosely-knit piece.
