Continuity mistake: When the Angels are describing how to break into the computer vault, they show the first guy putting his left hand up to the reader to gain entry. When Dylan (Drew's character) puts her hand up later on to gain entry when they're actually breaking in, it's also her left hand. But when they lift the prints from the beer bottle in the restaurant, he clearly lifts the bottle with his right hand, takes a drink, then puts the bottle down, never touching it with his left. This same mistake is repeated when they show Dylan looking at the fake hand being created and lifting up out of the goo - it's a right hand that pops up (even though Dylan correctly flexes and looks at her left hand as she admires her work). (00:34:50)
Continuity mistake: When Natalie is in the room preparing to enter the chamber to install the device on RedStar's system, she is wearing a white outfit from head to toe with a small oxygen mouthpiece for breathing. However, when the door opens to the room and she begins her gymnastic flips over to the system, the outfit no longer covers her hair and the oxygen mouthpiece is gone. There doesn't appear to be a hood attached to the outfit. (00:39:50)
Continuity mistake: The shards in the broken window, from which Drew hangs with her sheet, look different after the repetition. In the original take it's made up of many more fragments than after the slow-motion. (00:57:25)
Continuity mistake: Just after the explosion at the Angels' headquarters, Drew has soot all over her face, but in the final shot of her she's clean. Her hair's a lot neater too. (00:59:20)
Continuity mistake: When the girls figure out that Knox is after Charlie, and Dylan thinks of the picture and they zoom in onto "Townsend." The shot before the final shot of the photograph shows Knox's father's arm around Charlie, when in all the other shots, he has his arms above his head. (01:00:05)
Continuity mistake: How did all three Angels manage to get blown through Alex's grey car's window? Not only did Natalie park her red car in front of the grey car, but her car disappears totally before they are all blown backwards by the building explosion into the grey one. (01:00:47)
Continuity mistake: When Bosley is in the dungeon towards the end of the movie he is seen ripping his sheet to shreds trying to make a rope. If you look in the window where he throws his rope there is light coming in from outside - not necessarily daylight, but a floodlight or similar. From outside though, the wall is pitch black, with no light coming from the room either. (01:01:10)
Continuity mistake: In the scene where Tom Green's character is giving the Angels a ride in the boat, look behind the boat and you will see that the "frothy" ocean water churned up by the propellers only goes back a very short distance. The boat was obviously sitting in one place (drifting, actually) for a period of time and only started moving immediately before they started filming. (01:04:05)
Continuity mistake: When the Angels are driving in the tunnel, before they make a U turn they stop the car and cause a terrible traffic jam behind them. When the car has turned around, camera changes angles and the lane that was jammed with cars is now completely empty. (01:06:30)
Continuity mistake: After the Angels come out of the sea, they start walking towards a cave, dumping their rucksacks behind them and strip to their waists. Very attractive, and a dramatic view, but in the next shot they're crouched on the beach, getting equipment out of the backpacks they just dropped. If they needed stuff from out of them, why did they dump them and keep walking? (01:06:45)
Continuity mistake: As Lucy Liu is climbing up to the place Bosley has been kidnapped and brought to she is wearing a back pack. The first shot of her it is just a knapsack, then she has a large collapsible bow and arrow, far too large to fit in the pack. Where was it before? (01:07:50)
Continuity mistake: At the end of the movie, when Knoxx tracks down Charlie's phone call, Lucy Liu is up in the attic, trying to hack into the system that's locating Charlie. There's a satellite antenna right up in the attic, to which she connects her laptop. It's the same antenna Knoxx is using for the satellite uplink. It would be much easier to rip off the cables that connect Knoxx's computer to the Redstar satellites, wouldn't it? (01:11:50)
Continuity mistake: In the first fight between the girls and the Thin Man, he grabs some red hair - we see him with it at the race track. However, towards the end of the film he's creeping up behind Lucy Liu and we see him with black hair. Now, the point is that at no point has he fought with Lucy Liu and grabbed her hair - yes, he fights with her AFTERWARDS and grabs some of her hair, but when we see him holding the black hair in the bell tower, he has it before he's had a chance to get any. (01:11:50)
Continuity mistake: When Lucy Liu is fighting the Thin Man in the tower, the bell falls. Soon afterwards he heads towards her, sword swinging, and we can see the bell again on the right. (01:13:40)
Continuity mistake: When Lucy Liu is climbing a rope up the walls of the bad guy's castle lair, you can clearly see that she is wearing shoes without heels. But later on when she's fighting various bad guys, she's wearing four-inch heels. (01:13:50)
Continuity mistake: In the scene where the Angels are fighting on top of the tower, Lucy Liu and Crispin Glover do a spinning move. There is a close up on Lucy before she does the move and then in the next shot we see her and Crispin spinning out of the way. In the close up shot, we see her starting to spin to her right, but in the wide shot she's spinning to her left. (01:15:25)
Continuity mistake: In the finale when the girls are climbing up the helicopter, we see Cameron Diaz sitting down on the helicopter's leg. However, AFTER that scene, from a far shot of the helicopter, Cameron Diaz is still clinging on the leg, trying to climb it. (01:20:30)
Continuity mistake: During the helicopter scene at the end, the rope as well as the clamps they used to pull themselves up on suddenly disappear from underneath it. It's visible in most of the close-ups underneath the helicopter, but missing in others. (01:20:35)
Continuity mistake: When Dylan jumps from the copter, she has her jacket unzipped, and you can see her yellow shirt underneath, but when the Angels get out of the water, her jacket is zipped up. It's not like she had time to zip it while being blown out of the sky and washing ashore unconscious. (01:23:15)
Continuity mistake: At the end of the movie you see Charlie walking down the beach, then looking back at presumably the Angels, at that time it's sunset. When it goes back to a shot of the Angels and Bosley, there's still a bright blue sky as if it were still the afternoon. (01:26:15)
Suggested correction: Knox wasn't a trained pilot. Either he had no clue to what was going on, or he thought something may have been wrong, but didn't know what to do about it.
Taking off and landing a helicopter are by far the most intense and difficult part of a pilot's training. Seriously, 99% of learning to fly is learning how to land and take off. If the pilot is skilled enough to take off in a Huey he is easily skilled enough to notice a massive additional drag on his helicopter due to the additional weight of the angels and the air resistance put up by such a bulky protrusion on his aircraft. If he isn't skilled enough to notice that, he isn't skilled enough to take off in the first place.
