Factual error: In the Indycar scene, both Cameron Diaz and Crispin Glover couldn't jump in their cars and drive off without help from the pit crews because CART cars don't have starters installed. The cars must be started manually from the back by one of the crew. Also, Indycars must be kept at a very high RPM or else they will stall out, so the quiet scene on the bridge wouldn't happen because both cars would have died. And without a crew member present, they couldn't get the cars restarted for the game of chicken. (00:30:35)
Factual error: The airplane they jump out of at the beginning would be travelling at cruising altitude where it is roughly -30 outside with a wind chill of -30 and -10 for travelling at terminal velocity. They do so without using the Extreme Cold Weather clothing that parachutists must use at this height due to the fact that any exposed skin would be frostbitten within seconds. Also they have no means of breathing the amount of oxygen that a human needs as they are too high up to get an adequate supply.
Revealing mistake: When the Angels are driving through a tunnel and decide to turn around to get to the marina, there are distinct skid marks the exact same way the girls U-turn. Evidence of previous takes. (01:03:50)
Factual error: When the Angels are chasing Creepy Thin Man down the alley, he turns and fires approximately 20 shots at them without reloading. The luger pistol has an 8 shot magazine. (00:23:35)
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)
Factual error: At the end of the movie, the villain shoots a missile from his helicopter at a beach house. Just before he fires, Lucy Liu changes the missile (upon which she is sitting) from laser-guidance to heat-seeking, causing the missile to circle around and blow up the chopper. The heat-seeking missile would have locked onto the strong return from the beach, and not pursued a target that was behind it. (01:21:50)
Other mistake: As the girls learn about their assignment from Charlie, he shows them a film. The film shows Knox in a tree. His sweatshirt says "BOSTON" in white letters. It is backwards in that shot, and the scene following. (00:13:34)
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)
Factual error: When the two are falling from the plane, they achieve terminal velocity or 125 miles per hour. The parachutist from the helicopter grabs the bad guy and pulls the cord opening the parachute, which means achieving 4Gs or weighing four times your normal weight as deceleration from 125 mph to 18 mph takes place under a second. There is no way that that Angel could have held on to someone weighing four times their normal weight.
Factual error: Given that the Angels are all about stopping crime and so on, is it not a bit reckless that they would just rip the door off a flying plane? Anyone not wearing a seatbelt would have been sucked out and killed, which would undoubtedly cause Charlie a spot of bother in law cases and so forth. Just a thought. (00:03:15)
Continuity mistake: At the beginning when the guy with the bomb and Drew Barrymore's character, in disguise, are falling out of the plane the guy with the bomb has it still strapped to his chest but after they land in the boat the vest has disappeared. It reappears a few moments later but then again disappears. (00:04:10)
Other mistake: During the five man fight sequence with Drew, she does a split kick in the air and "kicks" two guys, but her foot is clearly a good distance away from even grazing the guy on the right anywhere on his body. (01:16:45)
Continuity mistake: After the two cars hit each other, and Crispin Glover's car is catapulted over the bridge, as his car falls, take a close look - there's no damage at all. Even though he skipped over Cameron Diaz's car rather than ploughed right into it, you'd expect there to be some indication... (00:32:30)
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.
