Other mistake: At the very beginning, just after Lucy and Linus exit the house, walk down the house steps and make it to the grass, the house steps do a little "jump". (00:00:20)
Continuity mistake: The fence which Linus tries to shove the pumpkin through at the start of the show, loses planks from one side to the next. On one side, the fence (to Linus's right) has nine planks. When the view changes to the opposite side, this same section of fence now has only seven planks. (00:01:05)
Continuity mistake: After choosing their pumpkin in the patch, Lucy is seen walking through a fence via a missing plank. The view then switches to the other side of the fence. Linus attempts to shove the huge pumpkin through the fence, but it won't fit. We then hear Linus rolling the pumpkin to the far end of the fence after which Linus and the pumpkin come back into view. However, after initially trying to get the pumpkin through the fence, although we have a great view through the fence, we never see Linus or the pumpkin go past the missing plank. (00:01:10)
Continuity mistake: When Lucy and Linus return to their home with the huge pumpkin, the house's surroundings are changed from what was seen just moments earlier at the beginning of the show. A bush next to the steps has gotten smaller and there is now a walkway leading to the house. (At the beginning, there seems to be nothing more than grass outside the front of the house.) Also, a tree, a garage, a telephone pole, a second house and a garbage can which they walked past at the start of the show, are not there when Lucy and Linus return home. (Though their own house steps have changed when Lucy and Linus return, it may simply be that they are now in shadow as the sun has, by then, gone down in the sky significantly.). (00:01:30)
Continuity mistake: When Lucy and Linus exit their house to mail Linus's letter, the outside surroundings are different again. There is now the trunk of a huge tree in the front yard, a house in the background and a public mailbox just steps from their front door. (00:07:10)
Continuity mistake: When Linus mails his letter to the Great Pumpkin, it can be seen that the mailbox has no writing on it. On close-ups, "U.S. MAIL" is written on the side of the box. (00:07:20)
Other mistake: When the kids leave Linus standing alone in the pumpkin patch, Sally decides to rush back to Linus, and when Linus explains that she'll see the Great Pumpkin with her own eyes, Sally's left arm is blue, the same color as her dress, then instantly changes to the normal flesh color within the same shot. (00:11:20)
Continuity mistake: When Snoopy arrives at the Halloween party, he slides down a set of curtains and then hides behind those curtains. In the same shot, Lucy approaches a tub of water atop which five apples are floating. When the shot changes, there are only four apples floating in the tub and Snoopy has now somehow gotten into the tub and is hiding under the water. The action is constant. How did Snoopy get from behind the curtain to under the water? (00:18:30)
Other mistake: When Snoopy starts sneaking through the pumpkin patch, Sally is standing with her arms crossed and Sally's hand is painted blue while talking to Linus. (00:20:35)
Continuity mistake: When Snoopy approaches the pumpkin patch, crawling on all fours, the moon is white, medium-sized and partially up in the sky. When the shot changes to Linus and Sally, the moon is yellow, gigantic and touching the horizon. After Sally's disillusionment, the moon disappears from the sky. (00:21:15)
Continuity mistake: When Lucy awakens at 4:00 AM she checks on Linus and then puts him to bed. In some shots there's a window over Linus' bed, but in other shots the window has vanished, and there's only a shelf over the bed. (00:23:10)
Continuity mistake: When Charlie Brown holds the door for Snoopy before the gang leaves to trick or treat, his costume doesn't have all the extra holes in it like it does in the scenes before and after.
Continuity mistake: When the kids are looking through their bags to see what they were given, suddenly a new kid in a ghost costume suddenly appears with them saying he got a quarter - he wasn't with them before.
Continuity mistake: When Charlie Brown is with the others before he shows all the holes in his costume, he's holding it and it shows only 2 holes about where they should be. But then when he brings it up, it's covered in holes.
Continuity mistake: When Linus and Lucy are walking to the mailbox, he has a letter in his hand. For a couple frames this letter and his arm suddenly disappear before returning.
Other mistake: When Lucy asks for an extra piece of candy for her brother during the Trick or Treat scene, her right hand has five fingers when she holds it up, but her left hand only has four fingers.
Character mistake: On the mailbox where Linus delivers his letter, on the side of the Mailbox is written "U.S Mail." That should be on the letter, not the mailbox. There should also be a period after the S making it U.S. Mail.
Other mistake: There is very little drawn correctly about the neighborhood as Lucy and Linus are walking through it in the beginning. There are houses dotted throughout, but all directly on the grass. There's no streets, no sidewalks, no driveways, and most don't even have a garage. However there is one random electric telephone pole they pass.
Continuity mistake: When Linus and Lucy are heading to the pumpkin patch at the beginning of the film, Linus takes his blanket with him, but when they pick up a pumpkin and march back, Linus no longer has his blanket.
Suggested correction: When they get to the pumpkin patch, Linus drops his blanket. When they leave, he leaves his blanket at the pumpkin patch. He might have forgotten it, but it's not a mistake.
Continuity mistake: When Linus is rolling the pumpkin, the position of the pumpkin goes from upside down to right way up between shots.
