Revealing mistake: When Troy says "I'll sing with her," Ms. Darbus turns around "in response" to his voice before he even says anything.
Revealing mistake: When the driver is taking Amanda to the airport at the end, all the dials on the car are at zero, so obviously the car is not moving at all.
Revealing mistake: When the truck leaps off the ferry, the underside is seen, exposing the still-flaming 'roll cannon' opening in the rear floorboard. This cannon is what caused the rear of the truck to rise, sending the truck flipping through the air. (01:52:30)
Revealing mistake: In the scene where Tristan and Isolde have their first secret talk in the market, when the camera is on Isolde, you can see that she is wearing contacts.
Revealing mistake: Jorge misses scanning the barcode on the tire by several inches at the end of the competition, but it rings up anyway.
Revealing mistake: When Gary and his friend are drinking Bud in the bar, the Bud label moves between shots to keep facing the camera. Gary doesn't touch the bottle.
Revealing mistake: In the scene at Frankie's house, Vanessa panics when she awakens and realizes Frankie and the children are away. When they re-enter, Frankie is heard telling the children that the carton he is carrying is "ice cream for Mommy." Frankie asks to speak with Vanessa in another room and sets the carton on a table. The sound of the connection makes it obvious the carton is completely empty.
Revealing mistake: When Julia does her dance for the firemen, they hit her with the fire hose and she gets knocked back. In a few shots after that, especially in the close-up of her swishing her hair back, you can see on her neck that the neck-fat piece has come loose.
Revealing mistake: When Harry Judd drops his drumstick down the trapdoor backstage, watch him carefully - He actually opens his hand and chucks it forward slightly.
Revealing mistake: In a scene where Fido is turned around, you can see a part of his head that is pink. However the rest of his body is grey.
Revealing mistake: In the scene where Rooster is driving/running away from the gangsters, he is supposed to be alone in his car but in one shot a hand appears and is holding on to the passenger side door from inside the car.
Revealing mistake: Kate's birthday is July 10th. When she is (with long hair) outside on the patio with Alex, you can see their breath as they talk, and there is not a living thing in the back yard, it's all dormant (as in late fall/winter).
Revealing mistake: Near the end of the film when Amanda and Dr. P almost take off together, there is a shot of them boarding. Look to the top right corner of the screen and for just a split second, you can see a glimpse of Roger chasing after them, along with Amanda's facial expression turn shocked. I'm pretty sure this happens because in the alternate ending Roger caught them when they were boarding.
Revealing mistake: When David Arquette is preparing to drive his rocket car, he does a u-turn to get pointed in the correct direction (towards his friend who is filming). The image is reversed at that point, so that he appears to be driving from the passenger side of the car.
Revealing mistake: Uhl talks about Eisenheim's childhood, and about the vanishing tree. Problem is that not only the tree disappears, but also his very own shadow, making him look as if he's floating in a landscape, thus giving away the green screen effect. (00:06:50)
Revealing mistake: In the badminton scene when Sadie flashes her breasts, her chest and abdomen are much more tanned than her hands and face are. The makeup people didn't match up the body double's skin tone to the actress'.
Revealing mistake: Throughout the scene when it is revealed that Jack has been offered a six month trial with the local team, the wall clock is stuck at the same minute and second. (00:18:30)
