Continuity mistake: When Mouth walks into the Walsh's house, there is a jacket hanging on one of the four hooks in the hallway, but when Mouth opens the door and sees Chunk at the gate the jacket's gone. We know it didn't just fall down, because we can see the floor below the hooks in later shots. (00:06:25)
Continuity mistake: When Chunk waits to be let in at the gate, Mikey pulls the cord to release the bowling ball and there is a long blue handle (broom?) leaning against the window, but it isn't there in previous and following shots. (00:07:30)
Continuity mistake: When Mama Fratelli says, "Follow me," and begins to walk along the side wall, past the skeleton's bone keys, her body faces the skeleton as she holds a large flashlight in her left hand and the wall with her right hand. Next overhead shot she is turned around to face the wall and the flashlight has switched hands. (01:24:10)
Continuity mistake: Aboard the Inferno in One-Eyed Willy's quarters, when Brand says, "Don't know. Who cares?" he's holding a candlestick with a candle. When he fills his pockets with the riches in the previous and following close-ups, the candlestick style differs and it's loaded with melted wax. (01:30:25)
Continuity mistake: When Mrs. Walsh, Rosalita and Mouth go back downstairs, after Mouth's interesting interpreter skills, in the first shot Rosalita holds her umbrella in her left hand upside down, but next shot it's in her right arm, right-side up. (00:12:25)
Continuity mistake: Just after the police chase passes Chunk at the window, the lead police car swerves and hits the road block, knocking it over in the wideshot. Next close-up that swerved car stops right beside the road block, not touching it. (00:04:20)
Continuity mistake: Up in the bedroom, when Mikey jumps on Brand who's bench pressing, he grabs hold of the bar and his hand is on the outside, with Brand's on the inside, but close-up their hands have switched. (00:05:50)
Continuity mistake: The large '007' with smiley faces that are painted on Data's utility belt cover changes throughout the shots, from the time we first see it at the start when he practices with the suction cup dart. (00:03:50 - 00:48:10)
Continuity mistake: When Data does the 'bully blinders', his utility belt is high up on his waist and the flashlights are at the same height. Next wideshot the belt is much lower and the right light is much higher than the left. (00:48:10)
Continuity mistake: The red bandana that Brand wears during the first half of the movie repeatedly changes the way it is folded around his forehead. Note the white/black distinctive designs that constantly change between shots. (00:40:30)
Continuity mistake: When Data's blue suction dart is stuck to the orange drum and the string is retracting, the thin orange string we saw being released from Data's belt has turned into a thicker brown cord, which pulls him toward the drum. (00:03:55)
Continuity mistake: At the start, when Data practices with the orange drum, just as the blue suction dart is released, the stick part remains on his belt while the suction cup and string go flying off, but in the next close-up the stick is between the string and suction cup, then the next shot of the belt shows the stick is gone. (00:03:50)
Continuity mistake: During his escape from the County Jail, when Jake tries to open the locked car door, in the interior shots looking out, the window between Francis and Jake is completely covered in water droplets, but in the exterior shot facing Francis that window is spotless. (00:01:45)
Revealing mistake: On Inferno's deck, when Data takes a stand against the Fratellis before he shoots the blue suction dart/string, the close-up of his utility belt is the same one seen at the start when he practices on the orange drum. Note the differences in the background and clothing/inventions under the coat. (01:31:50)
Continuity mistake: When Mouth lets the air out of Brand's bike tires, the reflectors on the spokes are in different positions in the close-ups. (00:23:35)
Continuity mistake: In the Walsh kitchen, after Mouth gets wet, Mikey unfolds the map and holds it in front of him. In the next close-up facing Mikey, Chunk, Data and Mouth, take note of their hair, particularly Chunk's and Data's. It is much shorter than previous and following shots. (00:22:30)
Continuity mistake: When they are with Chester Copperpot's remains, Mikey hands Data six sticks of candles and dynamite, but in the next shot Data takes hold of nine. (00:55:15)
Continuity mistake: After Andy kisses Mikey, when she tells Stef about it, her long hair is at her back, but in the close-ups her hair is in front of both shoulders, but next wideshot it's all behind again. (01:14:10)
Continuity mistake: In the attic scene, right when Mikey scolds Mouth for ruining the painting, you can see Brand standing next to the plasma lamp which is turned off. In the next shot of Brand reading the book, the plasma lamp is on. (00:14:50)
Revealing mistake: When the bats escape from the fireplace, it's obvious they are just black pieces of material.
