Continuity mistake: When Madison is speeding away in her Shelby Cobra with the Angels hanging on, she crashes into a theatre. While in the theatre, there are shots of the car in the background. It is a completely different car than the Shelby that Madison was driving a few minutes before. The racing stripes are thicker, the wheels are different and the car is actually a lot bigger. (01:31:30 - 01:33:10)
Factual error: Helicopter rotor blades do not unfold by themselves and there is no way to unfold them from inside the helicopter. A trained mechanic with the right tools and equipment (including the proper ladder for the job) will take a minimum of twenty minutes to rig a four bladed rotor, and that's if (s)he's in a hurry. An airborne (i.e. falling) helicopter? Forget it. (00:07:40)
Continuity mistake: When Demi Moore shoots the Angels off the side of the observatory, the bullet intended for Drew Barrymore hits her in the lower abdomen. Later in the movie when the Angels wake up on the lawn below the observatory, the only bullet hole in Drew's shirt is on her upper left chest. (01:17:05 - 01:20:25)
Continuity mistake: In the dirt bike racing scene, there's a long "slow-motion" shot that includes a large section of a very patchy-cloudy sky. In all other shots of the race, the sky is clear blue. (00:32:45)
Continuity mistake: When the Angels get shot off the observatory, Natalie is between Alex and Dylan. When the next shot shows them on the ground, Natalie is on the far right, past Dylan. (01:17:15)
Revealing mistake: Just after Madison says to the Angels, "Looks like one of the three amigos has gone adios" and Drew gets thrown by Madison, Drew hits the wall. For some reason, the camera vibrates.
Continuity mistake: After the car scene where Drew and Lucy fall off the car, it bounces at least 13 times and then goes through a theater. It is no longer dented or smashed at all. (01:32:05)
Continuity mistake: When Dylan tries to roundhouse kick Madison from behind, Madison catches her foot and twists it so her toes are pointing down. In the next frame just before Madison throws Dylan over her shoulder, Dylan's toes are pointing up. (01:15:25)
Deliberate mistake: Bosley is a school crossing guard trying to help the Angels. The children behind them say they are gonna be late for school. Of course they're going to be late because there is not a school within 10 miles of where they are standing. There's trees and what looks like a huge mountainside on the other side of the street. You can see this more visibly as the car that is about to run over Bosley is approaching. Done for a gag, but still ridiculous. (01:09:05)
Continuity mistake: When the Angels encounter Madison at the observatory they are supposedly wearing bullet-proof vests. You can tell through Nat's shirt she isn't wearing one. After they are shot, you can see the shirt is bulky from the vest. (01:17:00 - 01:20:00)
Audio problem: In the scene at the orphanage, when the boy runs down to the other boys reading the pornographic magazine, none of their mouths move when you hear "Look at those knockers".
Other mistake: When the Angels are in the bar in Mongolia, and Alex is trying to get out of the trapdoor with Ray Carter, a guy falls over the trapdoor entrance. When Dylan tries to move him, and sits down on top of him, the trapdoor falls in. Wouldn't that crush Alex and Ray Carter? (00:04:55)
