Poltergeist (1982)

Continuity mistake: The piece of licorice that Carol Anne puts into the cigar box with the dead parakeet "for when he's hungry" appears to be close to 6 inches long when she's placing it in the box but no more than a couple of inches long when it's shown in the box a few moments later. (00:10:10)

Continuity mistake: Just before the house starts to implode, Teague is backing away from it and as he does so, he passes a couple of white garbage bags on the sidewalk and backs into the street. In the next shot, taken from across the street showing bystanders being blown backwards, Teague is visible in the background; he's back on the sidewalk tripping backwards over the same bags he safely passed moments before. (01:48:10)

Continuity mistake: Toward the end, when Diane and the kids are trying to escape, they start into the kitchen only to see 2 coffins come up through the floor. The initial shot shows the coffins quickly shooting up to almost the same height and then stopping, but in the next shot, in which the coffin on the right opens, the one on the left is a couple of feet lower and is still slowly rising.

Continuity mistake: When Diane is about to dye her hair, the shampoo bottle changes positions between shots.

Continuity mistake: As the Freeling family is escaping through the side of their house, you will notice that Diane is holding a doll that looks like Carol Anne.

Other mistake: In the opening sequence, when Dana is in bed and hears Carol Anne say, "Hello, I can't hear you", for some reason there is a prosthetic leg lying across Dana's bed. (00:03:45)

Audio problem: When Carol Anne says "they're here" her mouth doesn't match the words.

Revealing mistake: When Diane is on the ceiling, a piece of something white falls right in front of her, landing on the ceiling. This shows the set was upside down and she was actually on the floor. The scene was shot on a rotating stage but the little piece that falls gives away the effect.

Revealing mistake: Diane runs back from the neighbor's house and falls into the pool. You can see where she is going to fall and she runs right to that spot. It looks like they did multiple takes.

Visible crew/equipment: Near the end when Diane is reaching for the kids and trying to get them out to the hallway, a film light is blatantly visible behind her. Also during the same scene the shadow of a fan can be seen in the hallway.

Continuity mistake: When the parapsychologists are attempting to record Carol Anne through the TV set, Ryan's hands are by his headphones, but the next shot shows him move his hands to his headphones again.

Continuity mistake: When Steve Freeling is in the living room with the Ghostbusters, he has a cigarette behind his ear. In another shot seconds later it disappears then reappears again.

Factual error: Robbie is grabbed by the big, gnarly tree outside his bedroom window during a severe thunderstorm, and Steve rushes outside to save the boy as a full-blown tornado passes overhead. The tornado sucks up the tree (which certainly weighs several tons); yet, completely defying physics, Steve and Robbie remain unaffected by the powerful updraft, even though the two are directly beneath the tornado vortex.

Visible crew/equipment: Near the end of the film in Carol Anne's bedroom, after the medium calls "Give me your hand" the edge of a giant fan is visible on the extreme right of the picture. (Maybe widescreen version only).

Continuity mistake: When the big throat is menacing the kids, Carol Anne's position swaps from being left or right to Robbie randomly between shots.

Continuity mistake: When the ghostbusters team goes upstairs with Steve for the first time, Ryan takes his bag off twice.

Sacha

Continuity mistake: When Robbie is trapped by the tree and Carol Ann is about to be abducted, his bed cover keeps changing back and forth from messy to perfectly folded.

Sacha

Continuity mistake: In the pool, Diane is surrounded by at least 4 bodies floating together; however, when she grabs the hose to climb up, half a second later, the overview of the pool shows just 2 bodies quite a distance each away from each other. In the next close-up, the 4 bodies reappear.

Sacha

Continuity mistake: When Robbie covers the clown, the Chewbacca print on the jacket keeps changing in every shot.

Sacha

Continuity mistake: Wen the tree grabs Robbie the toy by the window swaps from facing right to left back and forth.
