Continuity: When Dennis is in Mr. WIlson's bathroom after his bath, pouring mouthwash in his nose spray, Dennis has toothpaste all over his chin and mouth. When they show Dennis from the side, it is gone. From the front it is there again. This happens several times in the shot.

Continuity: When Dennis is in the bathtub you see some toys floating around in the tub. When it cuts from above him the toys are gone. Instead the whole tub is covered with foam.

Continuity: While Dennis is stoking Switchblade Sam's campfire, he flings an ember that falls down the back of Sam's pants. The smoke (and later the flame) are coming from the center seam, yet after Sam puts the fire out the hole is a couple of inches to the right.

Revealing: In the scene where Mr.Wilson slips on the bath water and falls, after he does the split you can see his right leg is fake.

Other: When Dennis is in the woods right before he bumps into Switchblade Sam, he passes an owl that hoots but the movement of it's throat aren't at all in conjunction with the noise.

Continuity: When Switchblade Sam is in the water and Dennis lowers him the rope, he barely gets it around his ankle. When he gets back onto the bank, it has somehow become neatly tied around his waist (obviously for the stunt that follows).

Continuity: When Joey is dragging the perambulator you see him dragging it while walking backwards. When it cuts he is dragging it behind him walking forward.

Continuity: When Dennis pinches Mr. Wilson when Mr. Wilson is pretending to be sick, you can see Dennis pinch but he doesn't use his index finger. When it cuts he is using his index finger.

Continuity: In the scene where Dennis and his mother are on their way to Margaret's house, the lock on the passenger's side door is locked and then unlocked when the camera view changes.

Continuity: One of the first shots of Switchblade Sam is a closeup of his face, in which the viewer can see he is wearing contact lenses. Kinda hard to believe this homeless-type villian with blackened and missing teeth, old torn clothes and unwashed stringy hair maintains contact lenses.
