Revealing mistake: When the boys go into the bear cave and all of the snakes are hissing, you can clearly see that one of the snakes is a rubber snake with a black stick attached to its head - the black stick is coming from a whole in the ground. It is not even a good snake, the 97 cent 'convenience store' variety.
Revealing mistake: Any time that Charlie is kicked by the kangaroo, they show him falling back onto the ground. But, if you look closely, they just used the same shot over and over. The exact same two lines in the dirt are to his left by his head each time.
Revealing mistake: After Helen finds the hair on Bob's suit, she goes to him while he is in the car and says," Have a great trip. I love you, so much.", Bob backs the car out of the driveway. He backs out and turns, but you can see his hand on the top of the steering wheel doesn't move. (00:47:05)
Revealing mistake: When the Rangers kick Oozemen's ass, the pink Ranger starts off with the "You guys make me sick sick sick -kick". While all Rangers are fighting, the blue one is just standing still next to the camera. You can see his shoe in the in the lower right corner waiting for his entrance. (00:22:30)
Revealing mistake: In the scene in the Russian bar, Dutch takes the bartender's gun. When he turns to hit her, the face of the stuntman replacing Alan Tudyk is visible. (01:03:40)
Revealing mistake: When Vicky and Donald Grisham are trying to get away in the car with the hardware store guy hanging on the end, in the furthest shot you can see the wheels aren't moving.
Revealing mistake: After Dante's Peak explodes for the final time, the pyroclastic cloud rolls down the mountain toward the town. Harry shouts "Don't look back, kids, don't look back." and then we are shown a wide shot of the truck zooming down the ash-choked streets. Unfortunately, it's painfully obvious that this is either a miniature or CGI shot, because the truck isn't leaving any tracks behind it or trailing any clouds of ash despite its high speed. (01:28:19)
Revealing mistake: When Thunderbird 3 lands in London, the jets do not burn the grass they land on.
Revealing mistake: At the party where Inspector Gadget lights a cigar for Scolex, he uses his thumb which flips open to reveal a flame. When they cut to the close-up of Scolex getting the cigar lit, you can see that there is a hand holding up a traditional lighter, and not Inspector Gadget's thumb any more.
Revealing mistake: Aslan is carrying Lucy and Susan on his back to the battle and is running at a very fast speed. If you look at the girls' hair though, it isn't moving at all, flat against their backs as if there wasn't any wind. (01:51:20)
Revealing mistake: When Shrek and Donkey are sitting by the fire and looking at the stars, when Donkey asks Shrek about "our swamp" and Shrek says "We?" When Shrek blinks, his right eyeball is slicing through his upper lid. (00:46:30)
Revealing mistake: Very near the end of the movie, when the NOAA director is viewed in the helicopter as it approaches NYC, the image is reversed, verified by the David Clark logo on his headset being reversed. There are two different shots of this just a few seconds apart, and they are both reversed.
Revealing mistake: This mistake occurs in the beginning of the film where the bandits rob the train. When Jackie is standing on the coal (or was it wood?) car you can see the train is passing a modern sign (you can see it on the right).
Revealing mistake: During the attack of the Global Sedition on the space station at the beginning of the film, several objects can be seen with dark grey boxes around them - CGI artifacts. One clear time is when Ranger 1 is saying "Damn, can't shake him". (00:02:35)
Revealing mistake: In the scene out West with the buffalo, notice the car driving in the distant background.
Revealing mistake: Near the end of the scene, when Bruce and Fox are in the tumbler Fox says "We never could get the damn bridge to work, but this baby works just fine" then Bruce turns the wheel to the left but the tumbler turns right. (00:57:45)
Revealing mistake: At the start of the hearse chase, when we first see the bad guys pull a hand-brake turn through 90 degrees in a small London side-street, if you look on the ground you can see the skid marks from what must have been the previous take.
Revealing mistake: In the park after the bad guys have been defeated and everyone starts returning to the museum, watch the T-Rex closely. In the overhead shot, he seemingly "floats" right through the branches of the trees which he normally would be moving. (01:34:50)
Revealing mistake: In driving rain, the faces of Nick and Suzanne appear to be completely dry.
Revealing mistake: Near the end of the film, when Bruce Willis is trying to escape into the Metro station, he swipes his fare card through the turnstile reader upside down - you can see the magnetic strip is visible above the slot. It still works anyway. (01:45:30)
