Corrected entry: When Allan meets Carl for the first time after coming out of the game, he asks what year it is, and Judy reminds him it is 1995. The badge on Carl's uniform states he has been serving in the police since 1974. The same day Allan gets sucked into the game, Carl is working at Parrish Shoes, not for the police. If this had been twenty six years prior to the events of the film, Carl would have been serving since 1969, not 1974.
Corrected entry: Alan manages to escape the cop by handcuffing his hand to the car door. To ensure that the cop can't drive after him, he throws the keys into the brush. But when he gets back in the car to go to Sir Sav-A-Lot, the keys are back in the ignition.
Corrected entry: Sarah rings her therapist as soon as she recovers from her faint in Alan Parish's living room, and she leaves a long involved message on his answering machine, asking him to ring her back. She doesn't leave a number! Was her shrink supposed to assume she's at the Parish's old house?
Corrected entry: In the stampede scene, the glass in the (computer generated) car window bends like rubber. They even used a picture of that one moment for worldwide publicity posters.
Corrected entry: At one point water rushes through the house, ripping the entire front of the house off. A few minutes later, the aunt runs up to the front of the house and tries to open the front door.
Corrected entry: When Alan has a shave and says that he's never done it before, his face is covered in cuts. A few seconds later, his face is shown completely clear again.
Corrected entry: When the hunter traps the young girl and Sarah at the store and holds them at gun point, the young girl cracks a smile. Would you be smiling?
Corrected entry: During the flood, the cop and the woman go up to the door. The cop draws his gun; just then the water rushes out at them. This much water would have probably caused him to lose his grip on the gun, and the last thing he'd be thinking about is putting it back, yet as he's floating down the street, his gun is back in the holster.
Corrected entry: When Aunt Nora calls the house and Judy picks up the phone, the phone is very sitting neatly for something that would have been knocked askew since a great herd of elephants, rhinos and zebras just came running through the house.
Corrected entry: When Alan arrives home with the Jumanji game, he starts to examine it in his lounge, then his Mother enters, and he slides the board game under the sofa. Then after he talks to his Mum, the camera cuts back to the game sitting under the sofa, yet now it is facing the other way, i.e has rotated 180°. You can clearly see this, because the board game has "JUMANJI" written on it, and the writing faces different directions in these two different shots. (00:08:50)
Corrected entry: During the scene when Alan is confronting the lion, there's a shot showing him throwing his knife into the floor, with the camera tracking the path of the knife. If you step-frame through this shot, you'll notice that the knife isn't really thrown. There are a couple frames where you can see both the blade of the knife that the actor is holding and the handle of a duplicate knife that's already embedded into the floor. (00:29:35)
Corrected entry: In the third to last scene we watch young Alan and Sarah carrying a wooden box tied up by rope that contains the Jumanji game. They throw it off a bridge into a river in their hometown. But in the final scene we see that the board game alone is lying in the sand on a beach side in Spain. So the board game managed to break out of the box it was in, and travel all the way to spain. Highly improbable.
Corrected entry: In the scene where the mosquitoes are seen for the first time, and Kirsten Dunst hits one throught the attic window with a tennis raquet, you can see the shards of glass that the (computer-generated) mosquito knocked out of the window falling down the inside of the wall, which doesn't make sense - if the mosquito was going outwards, surely the glass would too? (00:25:00)
Corrected entry: When Judy and Peter are waiting for the bus before school, they are standing next to the staircase. Peter has a piece of toast with jelly in his hand, when they hear the drums they run up the stairs, Peter still has the toast. After they reach the top the toast has disappeared. And there is no jelly on his fingers when he checks out the game, as there would be when a child runs upstairs with toast and jelly.
Corrected entry: This was the first time CGI was used to create animals. The CGI artists said the most difficult part was making the lion's mane look realistic.
