Revealing mistake: At the beginning of the film when a Judge is thrown out of the airplane, you can see a parachute is attached to him.
Visible crew/equipment: When the cop car chasing the tow truck does a complete flip in the air, a roll bar is clearly seen where there was none before.
Continuity mistake: In the "Corn Scene" when Pepto is eating with the bums, and he tells the bum that he has a piece of corn on his face, during cuts a white plastic knife suddenly appears beside his bowl.
Other mistake: After Nora leaves with the wrong bag, Snaps calls the Underwood home to ask someone to come over and switch them back. Later, Nora herself returns and Aldo makes the switch for her. Then the Underwood chauffeur comes to trade the bags, and Aldo does this for him. But Aldo would've known that Nora had already retrieved the correct bag, so why would he change them back?
Visible crew/equipment: During the scene where the grandmother and the monsters stop at a variety store in the tinted bus a camera man can be seen. As the bus pulls away, you can see the camera man standing there filming the scene quite clearly in the reflection of the bus windows as it pulls away. (00:24:30)
Continuity mistake: When Alec Baldwin finds Kim Basinger in Las Vegas, she is wearing a white dress with thin straps. One strap is continually off her shoulder - except for one shot after he has followed her into her dressing room. They shoot her back, and both straps are up. All other shots have the one strap off her shoulder.
Continuity mistake: In the first meeting with the man with the hat, Ice puts one foot on the portable cooler, but the position of the foot on the floor changes when there's a cut. Even more obvious, when she steps in front of him, the tip of her red stilettos touch his feet, but at the cut their tips are distant, and she moves in with her right foot first, as opposed as before.

Factual error: Hawking explains how time slows as one approaches a black hole's event horizon. To illustrate this a CGI-animated analog wristwatch is shown ticking away the seconds progressively more slowly. It's the kind of watch that ticks intermittently: once each second the hand sweeps one second-long increment around the dial and then waits one more second to sweep another increment. In the animation, the frequency of the ticks lessens, but the speed at which the hand sweeps each increment stays the same. To be consistent, the sweep-speed needs to slow down just as much as the tick-frequency. (00:36:30)
