Continuity mistake: When Natalie is talking to the surfer by his car, Alex and Dylan are under the car looking through his belongings. After he gets into the car to drive off, it cuts to Natalie and she says something, cuts back to the surfer pulling away in his car and then cuts to a shot of Dylan but you can see the surfer's leg/towel in the shot. Shouldn't he already be in the car? (00:28:45)
Continuity mistake: This is during the fight between the Angels and O'Grady's thugs. Seamus has Dylan against a container. He aims to punch Dylan but misses and hits the container to the right of her face instead. There's white writing on the container. Cut to the next shot and the writing is now to the left of Dylan's face. (00:56:25)
Continuity mistake: In the roof fight, Dylan gets knocked off the roof and grabs the fallen E. Her hands were holding on to the lower piece, but in the next shot her hands are at the top.
Continuity mistake: When Natalie jumps into the boat she is wearing flat heeled shoes, but in the earlier fire scene she is wearing black stiletto boots. (This is visible in zoom and slo-mo.) (00:58:55)
Continuity mistake: At the end of the Angels' last fight with Demi Moore, we get a closeup of Demi's mouth. It is bloody and her teeth are covered in red. A few seconds later, after she falls backward through the floor and begins to scream, there is no blood on her face and her teeth are pearly white. (01:35:10)
Visible crew/equipment: When the Angels are racing in the "Coal Bowl" we can see a camera on top of the bridge structure. Watch for a wide angle shot and you can see the camera moving at the same speed as the dirt bikes, at the very top of the screen.
Visible crew/equipment: When the O'Grady mob are fighting the Angels, Alex turns off the lights. Just after they flip over the men, you can easily see the harnesses at the top of the screen. (00:54:25)
Continuity mistake: When Alex is rescuing Ray Carter, the blood on his shirt is on the right hand side. When Ray says, "Ah, my ribs", the blood is on the left hand side. Afterwards, the blood's on the right hand side.
Plot hole: Why would Madison Lee put the bomb in the car if she was so convinced that the Angels were dead? If she wanted to off them just in case, she could have shot them while they were unconscious. (01:21:50)
Continuity mistake: When Seamus surprises the Angels in the hull of the ship, Natalie drops the champagne bottle, which explodes spraying champagne everywhere. But for the rest of the scene, the champagne and the shattered remains of the bottle are gone.
Visible crew/equipment: As the Angels are all hanging on the blue car that Madison is driving in the end, you can briefly see the small hook at Lucy's stomach, that was keeping her secure. (01:31:45)
Continuity mistake: When the Angels are dancing at Natalie's place, Alex is wearing very high wedge heels. When they tip over the couch, Alex is suddenly barefoot. (00:13:30)
Continuity mistake: When the Angels are sitting at the desks talking to mother superior, she asks the Angels to move forward. Watch Cameron Diaz. The first time she grasps her desk to bring it forward, it's on the front bit. Then it shows a shot from behind and she is grasping it from the sides, then back to the front shot and she is grasping it from the front again. (00:41:45)
Factual error: In the scene where the helicopter falls off the bridge there isn't enough time to start the helicopter, let the systems get enough pressure and get the blades rotating fast enough to provide enough lift to fly plus at the angle the helicopter was falling it couldn't even auto rotate. (00:07:40)
Continuity mistake: At the start of the rooftop fighting scene, Madison opens the door and leaves it open. When the Angels pull her guns apart, the door is closed.
Continuity mistake: At the beginning when Natalie kicks the door open, there's a pretty bad blizzard outside, but when they jump out the window minutes later, it's bright and sunny outside.
Revealing mistake: When the Angels are fighting on the rooftop, Demi Moore stands on another building nearby with a dress and a thing around her hands. Her hands aren't free obviously, but as she peeks through the telescope you can see the ocular moving around following the Angels and when the shot ends, her hands are still in the thing. (01:26:10)
Character mistake: Close to the end, Madison is looking over the H.A.L.O. list on her laptop. When Dylan's profile pops up, her last name, Saunders, is misspelled as Sanders.
Factual error: When Lucy L. is using the gas pipe as a flamethrower, it is suddenly turned off afterward. This could be because of one of the other characters turning the handle, but if they turned it off in that way (or any way), the flame would go inside the tube and make the tank blow up. (00:58:40)
Continuity mistake: When the Angels find the photos on Emmet's body at the coal bowl, the picture of Helen Zaas shows her holding her Lucky lighter. If you look closely, you can see that it is completely different to the Lucky lighter which Dylan carries. The stars part of the 'Stars and Stripes' design cover the whole lid on Dylan's lighter, but on Helen Zaas's lighter it only covers half of the lid. (00:59:50)
Answer: It is making fun of the show CSI. Even still, there are ways of telling if someone had a knee problem by the way they walk and put pressure on the foot. Being able to tell if it was a torn tendon, I don't think so. Check out the way people run and you can tell if they have hurt something in the past because of which leg they favor.
