Continuity: In the scene where Alan explains who he is to Sarah, she peers out through a door that's only open a crack. But when the shot cuts to Alan, his entire head and practially both his shoulders are visible through the door. When it switches back to Sarah, Alan appears to be at least two feet away (since he's totally out of the shot) and the door is still open the crack of a few inches.

Visible crew/equipment: Just before the monsoon, everyone is in the attic and Judy tells Sarah that she needs to roll a 12 to win. When it cuts to Peter, you can see his tail behind him, and the wire attached to the tail is visible, holding it up and swinging it about.

Deliberate "mistake": When the house is splitting in two, the board game should have fallen long before it actually does.

Continuity: When Alan's dad enters the car, he turns it on, yet you don't hear the engine start. When he shifts gears, you finally hear it start.

Revealing: 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.

Revealing: When Alan's face is stuck into the floorboards, after they had turned to quicksand, the boards assumingly go back to being hard and wooden, yet in shots of Alan talking you can see the boards bounce/wobble slightly, showing they are rubber.

Visible crew/equipment: When the lion first emerges from the Jumanji, Alan tackles with it and it then jumps at him, and lands on a long carpet, and goes sliding along on the carpet, into a bedroom. The black wire used for pulling the carpet along is visible, yet best seen in slow motion.

Continuity: The licence plate on Carl's car is "G2298" but after finding the car which the monkeys had smashed into a tree, as he reverses, the plate is "DBA 454."

Continuity: When Alan is eating dinner, and his father is shouting at him, the fork and knife on Alan's dinner plate moves around between shots.

Continuity: While Alan is handcuffing Carl to the police car, the sky is clear and the sun is shining from the left (driver's) side of the car (indicated by strong shadows). As Alan is tossing the cuff keys away, the camera cuts to a view of the back of the police car which was shot on an overcast day, with the shadows very muted, and the sun coming from the car's right side. The view cuts again as Alan turns to run back to the police car, and we're back in bright sunlight from the left side. A couple shots later, as the car is reversing into the quick U-turn, the sun is shining from the car's right side again, this time with strong shadows.

Revealing: During the monsoon scene, Sarah has both her feet aginst the jaws of the crocodile, and so Alan jumps from the chandelier, and dives into the water. As he dives into the water, watch Sarah's feet, and her left foot slips into the crocodiles mouth, and his upper jaw slams down on it! The crocodile has a row of sharp teeth on at the front of it's mouth, which come down onto her shoe. That would be painful, yet she doesn't scream/limp/complain.

Continuity: When Alan drops the dice, after being startled by the clock chimimng, one die reads 3, the other 2. Yet when his board piece starts to move, you can see both of the sides of the dice, both reading 2.

Continuity: As Mrs. Thomas is being taken from her car, after being bitten by the mosquito, the men put her on a pedestal and you can see she is wearing long green boots that nearly reach up to her knees. Yet when they are putting her into the ambulance, she has black heeled shoes on.

Continuity: When Robin Williams and the cop are driving to the store in the cop car after the windshield was broken, neither of their hair is messed up and they can see clearly.

Other: 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?

Continuity: 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.

Continuity: When the hunter fires at the cop (with his old gun) he fires once and the cop ducks behind the car. We see three bullet holes in the car when there should only be one.
