Continuity mistake: There's an electrical outlet on the wall below the window (aligned with the window shade's loop) in Sid's room near the Megadork poster, but when Sid throws Woody to the floor and raises the shade (before he scorches Woody's forehead with the magnifying glass), that outlet has vanished.
Continuity mistake: When Johnny Cage is fighting Scorpion, and he does his human spear, Johnny runs until he stops at the tree. The spear then catches up, and becomes wrapped around the tree in front of Johnny. When the camera changes view, the spear is just leaning on the tree. The camera changes view again and the spear is wrapped around the tree again. When Scorpion pulls the spear back, it goes straight back, and doesn't unwind around the tree.
Other mistake: In the scene where Robin Williams tells Sarah that she needs a 12 to win, she rolls a 3. The next time she rolls, Robin tells her she needs a 7 to win.
Continuity mistake: As Brian lands the plane down to Bangor, his headset is on in a frontal shot, but in a reverse shot it isn't. (00:47:05)
Visible crew/equipment: When the priest arrives and when he later walks to the house, lighting screens are reflected on his glasses.
Continuity mistake: At the beginning, Nix threatens young Dorthea with a real madrill, but that's all we see of it. It's never shown being put away, and it's not there when Swann and his crew break in to incapacitate Nix.
Continuity mistake: The pictures of Sara's parents in the locket switch places throughout the movie.
Continuity mistake: When Omri receives his new skateboard as a birthday present the deck is red with two white stripes. For the rest of the film it is red with blue stripes.
Continuity mistake: When they call the sausage company in Omaha, it is busy. When they show the phone in a couple shots later, it has more that one line and shouldn't have been busy.
Continuity mistake: Young Brian plays with his Star Trek figures on the carpet. When Fluke comes in, between shots the position of the other figures on the carpet has changed.
Continuity mistake: In the tournament at the end, the other people on horses that are competing don't even try to knock them off their horses.
Continuity mistake: During the Jacob's Ladder demonstration, the classroom clock remains at 8:10 throughout most of the scene. Then, in several brief flashes, it's 8:15, then 8:10 again, and finally 8:13. (00:32:00)
Continuity mistake: In the scene when Junior cuts the tree with his chainsaw, when he looks up to see how high it is, we can see it has branches. In the next scene when the tree falls on Scoutmaster Flimm, it doesn't have them at all and is cut straight at the top. (00:29:40 - 00:31:00)
Revealing mistake: After Lucifer kills Gabriel, we get close-ups of Lucifer where the outline of his contact lenses are visible.
Continuity mistake: When Marie and Nutcracker are in Christmas Wood, some shooting stars fall to them and turn into sugar plums. In the first shot there are 3 of them, but when it cuts to the next shot where they turn into plums, suddenly there are 5. Then when the plums come down and begin circling around Nutcracker and Marie, there are 8 of them.
Visible crew/equipment: When Jeremy impales himself on the silver ritual knife, watch as the "knife" bends under the weight of his body - an obvious rubber prop.
Factual error: Set in 1955, Tom Holman enters a construction site with an orange warning sign. Prior to 1971, construction signs were yellow.
Factual error: Calamity Jane was not Pecos Bills love interest. According to legend Pecos Bill was married to Slue Foot Sue another tall tale. Whereas Calamity Jane was an actual historic figure.
Continuity mistake: Susan Lucci's hair color goes back and forth from reddish brown to black in several scenes.
Revealing mistake: When Annie's boyfriend is killed, she runs over to Candyman and scratches his face open and bees pour out. You can easily see the head is a prop.
