Factual error: When performing CPR on Elena, Robert doesn't tilt her head back. As a former firefighter, he would know one of the first steps of CPR is to tilt the victim's head back to clear the airway. His rhythm is also way off.
Suggested correction: Tilting the head back to clear the airway isn't practised any more, due to exacerbating possible neck/spinal injuries. Instead, one would do a chin lift to clear the airway. But alas, he didn't do that either.
Paramedic here. The head tilt-chin lift is absolutely still practised today and is definitely our go to manoeuvre for CPR. You're thinking of the jaw thrust manoeuvre where we do it when we suspect spinal injury, which Elena did not have.
Former Volunteer First Responder and Ambulance driver part-time but also volunteer here. It actually depends on the SOP of the company in which you serve. Liability purpose has us practising caution in otherwise duty-to-act scenarios. While you are always to remain either Red Cross or American Heart certified in CPR, ALS guidelines and SOPs still govern the practice in which you are performing and can be effected by the decisions of your local Medical Director, but I digress.
Factual error: The poem Isolde recites, John Donne's "The Good-Morrow", is a 17th-century work, which is centuries later than the movie's time period.
Continuity mistake: When Magneto lands the Golden Gate Bridge on the island, as it hits land it is still very light. When the Brotherhood start to walk toward the island, it cuts to a wide shot of them still walking on the bridge, and it's suddenly dark.
Plot hole: There are six metal bars mounted around the circumference of the water wheel's axle. In the wheel's interior, when Jack frees himself he lands on his feet, begins to run and promptly hits his head on one of those mounted axle bars, then falls out. Moments later, when Jack returns and runs in the wheel, he is shorter (way more than a foot) than all six of the mounted axle bars spinning with the water wheel, which would make that previous shot impossible, however humorous it is. (01:52:40 - 01:53:55)
Continuity mistake: In a scene towards the end of the movie, where Bond and Vesper are lying on the beach, Bond has sand on his back throughout most of the scene. When they start to kiss, in the distant shot towards the end of the scene, he has no sand on his back at all. (01:57:10)
Other mistake: When Jaguar Paw is running to reach the corn to escape and gets knocked down by an arrow; Middle Eye was about to whack him when Blunted intervened. You can hear Middle Eye say in English "Get off me!" while he's being held back. (01:27:52)
Factual error: Dexter the capuchin is in the African mammal display. Capuchins come from South America.
Continuity mistake: Right after Queen Latifah hits her head and is having a fantasy, LL Cool J is unbuttoning his shirt. The scene cuts to Queen Latifah and when it cuts back his shirt is buttoned up and his tie is tied properly. It cuts back to Queen Latifah and back to LL Cool J where his shirt is now once again completely unbuttoned. (00:14:00)
Visible crew/equipment: When Lois pulls up to the house where the blackout was traced to, she hears some music coming from the boat down at the dock. As the camera pans upwards over the car, as she steps out, the whole camera and a crew member are reflected in the side of the car.
Factual error: In the beginning of the movie William supposedly boards the train in Lincoln, Nebraska. All the vehicles in the train are from Europe and never rolled in the United States. (00:03:35)
Continuity mistake: Right before battle, Nasuada is showing Eragon Saphira's dragon armor. The helmet is full face, with two little slits for eyes. When it shows Saphira wearing it, the helmet covers only the top part of her head and cuts off above her eyes. (01:20:35 - 01:22:30)
Continuity mistake: In the shot after Robin Williams has been sprayed to wash off the crap from the RV he is bone dry after the spraying is complete. They only show his upper body at this point but the spraying would have been over his entire body.
Continuity mistake: During the scene where Rita hugs Roddy for giving her the jewels,When it shows Rita's back, Roddy's hand skips from Rita's upper back to Rita's lower back. (01:00:30)
Deliberate mistake: Bare shoulders are forbidden in the Vatican premises, so the sexy dresses in the party would not be allowed.
Other mistake: Whenever Verne is inside his shell, he has a tail (and references to it "tingling" are made throughout the movie), however, when he is out of his shell he has human-style buttocks and no tail.
Factual error: In the scene in Kono, one of the child soldiers is seen with a Game Boy Advance SP, which was released in 2003, but the movie takes place in the 90's.
Plot hole: The whole plot of the first "Brother Bear" was that Kenai had to go to that mountain to become human. But at the end of this movie, the spirits were about to change Kenai back into a human in the middle of a cliff, which makes the entire first movie completely pointless.
Character mistake: When they arrive at the motel, the mother says that the grandpa is in room 13, but when he opens his door it is room 208.
Audio problem: Near the end when Drake is playing Hollywood Girl and gets into the bridge (the steady drum beat part) you can obviously tell he's mouthing the words.
Continuity mistake: When Jerry and the Dr. are talking in the tent the first night on the way to the mountain, the Dr. shows Jerry a notebook with a picture of his wife and son. Jerry hands the notebook back twice in a repeat of the same shot.
