Corrected entry: In the scene where Gunther is sitting in his backyard playing with an apple, Switchbade Sam walks up to him and stabs the apple right out of Gunther's hand. If you look at it in slow motion you can see that the hand holding the apple as Sam stabs it is plastic.
Corrected entry: After Dennis makes Mr. Wilson miss the blossoming of his 40-year-old plant, Mr. Wilson tells the boy, "I don't want to see you, I don't want to know you. Get out of my way." However, when Dennis runs away and Mr. Wilson starts to feel guilty, we hear him recount in his head all the angry comments he ever made to or about Dennis. This time it comes out, "I don't want to know you, I don't want to see you. Get out of my way."
Corrected entry: When Dennis gets off his bike, it tips back and the bad guy falls. Dennis is much lighter than the bad guy, so how could he balance the wagon?
Corrected entry: When Dennis is in the garage trying to clean up the spilled paint, he is using a shop vac. When he takes it outside to empty it, he hits a switch to change the vac from suck to blow. Shop vacs don't work this way. They have two openings on the device, one for pulling air in, and the other for pushing air out. In order to use the vac as a blower, you must take the hose out of one hole and put it into the other. The switch was also mislabeled: the switch labeled "In" and "Out" is in reality the On/Off switch.
Corrected entry: Where Dennis pushes the "Print" button at the end, we can see the last of the lady's images (2-3 copies) come through the machine after she fell to the ground, but then the photocopier stops copying. Shouldn't it continue copying after she's fallen?
