Revealing mistake: When Herbie is being pulled from the truck at Crazy Dave's, Herbie goes into reverse and the camera does a closeup shot of one of the rear wheels reversing. If you look carefully, you can see an extra set of small wheels behind the tyre which are obviously propping the car up enough so that the cars proper wheels will only skid and not get any traction.
Revealing mistake: There is one shot of the Duke boys in their car talking to Uncle Jessie with the CB radio. You can hear Uncle Jessie respond (through the radio) while Bo/Luke still has the button on the microphone pressed. When the button on the mic is pressed, no sound comes out of a CB radio at all, as they cannot transmit and receive at the same time.
Revealing mistake: When the talons and E.D.I. attack the fort during their first mission, the explosions show the use of pyrotechnics when A.T.S. missiles explode in a simple blast.
Revealing mistake: As Lady Tottington leaves Wallace's home, the ivy between the windows on the left suddenly changes a bit- a portion gets squashed flat (about 2 bricks down and to the left of the house address numbers) as the area gets a bit blurry. The modelers must have not noticed bumping it while working with the doll. (00:57:15)
Revealing mistake: Towards the end when Sarah and Juno team up to find the exit, they pass underneath some thin stalactites. As Sarah goes under them, one of them wobbles as if it is made of rubber. In reality stalactites are rigid formations and are not supposed to wobble when touched. (01:26:40)
Revealing mistake: Right after Darius blows the boats, Steele is on the dock firing at him. It is shown that he shoots a couple rounds but his finger is not on the trigger. (00:24:00)
Revealing mistake: When Ryer and Rand jump off Rand's window and down to the street, they land on a tree. Notice the severed branches; instead of being broken [presumably from the falling bodies], they are cut rather smoothly.
Revealing mistake: When Victor Von Doom is shown proposing to Sue Storm in the space station, for a short moment you can see a reflection of the blue screens they used to create "space".
Revealing mistake: When Charlie is climbing the wall you can see a handhold screwed into the wall when she lets go with her right hand. (00:59:45)
Revealing mistake: When the guys are on the jet skis, when they are showing off, you can tell they are stunt doubles.
Revealing mistake: In the first person shooter sequence, when Reaper gets the chainsaw, there are many parts where he is moving it around near Pinky, now the beast thing, and it does not have a shadow, and at other times when it is at the same angle, it does.
Revealing mistake: When Walter, Danny and the astronaut are in the kitchen breaking stuff to burn, the smaller boy tries to smash an old style broom on the table. He tries three times, on his final try the shank breaks in half, revealing where it had been sawn nearly all the way through in nice clean line, with only a splintery piece showing where it really snapped.
Revealing mistake: When Loki disguised as the delivery person grabs the baby, he's replaced by an obvious doll, with pale yellowish skin and lighter hair colour.
