Revealing mistake: The blonde model, who is always getting surgery done to change her body, one day has two eye patches on. If you look closely, you can see the eye patches have peep holes, made to look invisible to viewers, but she was falling all over the place and bumping into things and said she couldn't see.
Revealing mistake: In the beginning, Gordon is driving his truck and "drinking" something out of a thermal mug. He's be-bopping around so much it would have spilled all over him. If you look closely, you can see he's not really drinking at all.
Revealing mistake: When Diane and Jack are coming back from the store to get groceries, Diane throws a piece of paper out of the car and you see it fall straight down. If they were actually driving it would have flown backwards.
Revealing mistake: When Liv Tyler is washing the car, after she squeezes the sponge onto her chest and leans down, the next shot is shown in reverse - the soap and the water travel upwards. (00:36:00)
Revealing mistake: When Chabot and Vlad are on the ceiling, one of Chabot's fake nails falls off.
Revealing mistake: In the last shot of Elwood machine gunning his Mercedes, he's run out of ammo - there's no belt left.
Revealing mistake: At the beginning of the movie when Gordy is doing the voices of the drawings, he creases one of the pictures and it lifts up. You can see that the picture is a photocopy of the original, although apparently these drawings are original. This happens several other times in the movie.
Revealing mistake: In the opening scene Vinnie Jones is driving the red Mercedes CLK convertible. As the scene switches views of him driving, the view of Vinnie and the car changes in a flipped shot.
Revealing mistake: When Beverly is trying two throw herself down the stairs after she finds out she's pregnant, the padding on her behind to go down stairs shows through her pajamas. (00:30:40)
Revealing mistake: When Hubert breaks the tooth on the first transexual you can see light reflected on the lacquer covering the real tooth in his mouth. (00:06:40)
Revealing mistake: In the scene where unit 91 is calling in the Spurbury Police car, it is obvious the car's ignition is not turned on.
Revealing mistake: In the intro (or one of the intros, rather), they narrate Pootie Tang's origin. A fake newspaper called "New York Pone" is shown, with the front page dedicated to baby Pootie and his invention of a new language. All fun and everything, but the prop is sloppy; you can read below the name of this fake 70s newspaper the URL of the New York Post' s website and the date in April 2001. (00:08:35)
Revealing mistake: Grandma handles the remote control in clumsy fashion, sending the model helicopter too close to the buffet and ruining the party. That's the idea at least; in truth, the cakes are catapulted in the air by devices placed under them. They are easy to spot because of the wrong timing, the geyser-like puffs of smoke they create, and you can even see marks at the bottom of a tray. (00:07:30)
Revealing mistake: In the movie when they are setting up the new junket hotel for reporters, it's stated there is a brand new Hyatt in the desert that is just opening. However, when it's shown for the very first time, the white line and word "stop" written on the pavement are faded, indicating they've been there a while.
Revealing mistake: At the start, when the girls in the bunk are standing in front of the mirror, the first shot of them looks as if the camera is facing the mirror and we're seeing their reflection, but note that neither the buttons on Alexa's blouse nor her white bracelet are on the opposite side. The "mirror" is actually regular glass with the girls standing behind the glass to mimic a reflection, though Alexa's blouse and bracelet reveal the secret. (00:03:05)
Revealing mistake: When the group comes across the first ass-blaster, it hops out from behind the fence. Pay attention to its right leg when it jumps out and you'll see a rock on the ground just appear behind it. After it spots them, it stomps a few times. While it's stomping, pay close attention to the rock and you'll see it and some of the ground around it just disappear after a few frames. This rock also isn't visible in any other part of the scene. (01:01:10)
Revealing mistake: The tentacle slaps the Captain, but he's already got the wound.
Revealing mistake: When Corky (as Agent Pissant) is taking the perp in and starts to sing, the car makes a full 90° left turn (you can tell by the background), yet he never turns the wheel and both hands stay on the top of the wheel.
