Continuity mistake: During Danny's drunken yelling scene he swoops a table ALMOST clear of its papers, meaning there are still a few papers messily left on the table. However, a few shots later, those papers are mysteriously missing. (01:47:20)
Other mistake: Just before the Charger crashes, a tow bar connecting both vehicles is visible on the Mustang's front bumper.
Visible crew/equipment: When the Mini Coopers jump out of the sewage tunnel, you can see the black ramp they launch off of to give the tunnel exit more of a dramatic effect. (01:36:15)
Revealing mistake: When Jim hits the brakes in his stolen patrol car, the two pursuing police cars turn and flip over and over. As they roll, the 'roll cannon' is visible on the underside of one of the cars (a round steel tube in a hole in the floor) and at left, the two cannon slugs from both cars bounce down the road. This device fires the slug downward, and the force behind it lifts the car when the slug hits the road, launching the car over.
Other mistake: When Big Momma is taking a shower, you can clearly see that the shower head is a mirror, with the water coming only out of the top, and when Big Momma bends over, you can also see her reflection in the shower head. (00:12:00)
Continuity mistake: After Gromit runs away he starts looking at signs. In one shot, a blue sign goes over the one Gromit is reading (Room to Let), but in the next shot it's not. (00:12:20)
Continuity mistake: When Robin steps foot into Poison Ivy's lair she is laid out on her flower bed. If you look at the sleeves of her costume, the ends of the sleeves are fringed in a simple leaf like design. Robin spurns Poison Ivy's affections, and an enfuriated Ivy pushes him into the lily pad pool. She is then confronted by Batman, and a soon to arrive Batgirl. Now - look at the huge, obvious, black rubber "thorn" bracelets that suddenly appear on each of her wrists. (01:37:25)
Continuity mistake: When Amsterdam arrives in New York City and is talking to his new friend, the bag he is holding switches from being held under his arm (camera shot from front) to being carried on his back (camera shot from the back). This happens at least four times in a row during the same scene. (00:22:55)
Visible crew/equipment: After Bond received a lighter from Felix and Della, he uses it and the flame is big. In the beginning and the end, you can see a tube is connected to the lighter and the tube goes into his suit. (00:15:00)
