Factual error: During CONTROL's paintball training session, a barrel view of a bullet exiting the gun is shown as it travels to its target. However, the entire bullet is shown, casing and all, instead of just the bullet. (00:09:10)
Plot hole: If Bradley Cooper was able to "quintuple" his money every day in the market as he claims to have done, he would have been able to earn the $100k he borrowed from a loan shark within a few days, starting from $800. Alternatively, he is shown in one scene winning a pot in poker where he could presumably also make a large amount of "seed" money from gambling. There was no need to borrow such a small sum of money from a loan shark, making the entire sub-plot unnecessary.
Continuity mistake: The tyres on the crotch rocket motorcycles they were riding kept changing from knobbly tyres to road slicks, back and forth depending on what terrain they were on. Easiest to see when Ethan skids on the road to avoid the white van - clear shot of slick tyres - then about 30 seconds later they're on the dirt, he skids into the old car and you can easily see that he's got off-road tyres front and back.
Revealing mistake: When Dracula flies into the room to stop his brides from devouring Jonathan, the board carrying him is visible. (00:34:10)
Plot hole: Necros had absolutely no way of knowing that Bond and Saunders had arranged to meet at the café when they did and wouldn't have had anywhere near enough time to track them down and set up his elaborate booby trap. Saunders only suggested the meeting place and time a few hours earlier, and it was kept strictly between him and Bond. The scene in Tangier, where Whittaker tells Necros to kill another British agent, takes place on the same day Bond arrived in Vienna; meaning that Necros got from Tangier to Vienna (a 5-hour plus flight), tracked down Saunders, acquired the materials to booby trap the café doors (or had planned this ahead of time - unlikely), and set the trap up well in advance of him and Bond getting to the fairground. There was nowhere near enough time for all of that to happen without Necros having psychic knowledge of Saunders' movements.
Factual error: The movie is supposed to take place in and around New York City, however during the car chase where Angelina and Brad are fighting off the three BMW's, a wide shot clearly shows a street sign announcing Los Angeles.
Plot hole: There is a barely credible explanation for the fact that a guest cannot be injured or killed by being shot in Westworld, but what about the vicious fistfight we see in the bar? People are injured or killed in bar brawls all the time, and this one was incredibly violent. How do they prevent guests from being injured or killed by the cutting and stabbing weapons we see in Medieval and Roman World? Guests are supposed to fight each other, not just robots - they cannot be 'programmed' to lose! Delos is going be sued into bankruptcy within a week of the first guest arriving. Quite apart from the legal position, think about the bad publicity! Who is going to pay the huge fees demanded by the parks owners when the media is constantly reporting on the guests who wound up dead or with life changing injuries?
Suggested correction: The explanation given in the TV show would seem to easily apply to the original film as well: guests can be injured, but not to the point that it would leave a lasting mark. The park has access to futuristic medical techniques, so they can heal most non-life-threatening injuries easily. Also the guests almost certainly sign waivers, so in the event of serious injury the park isn't liable.
Suggested correction: It's easy to nitpick the factual details of "Westworld," the screenplay of which was written on-the-fly on a fairly limited budget, even by early 1970s' standards. Author Michael Crichton (who also wrote "The Andromeda Strain," "The Terminal Man," "Congo," "Sphere," "Jurassic Park" and several other technological thrillers) himself acknowledged that Westworld was more a visual story (like a comic book) than a cerebral piece of science fiction, and he learned on this movie that suspension of disbelief outweighed technical or even factual details, if he wanted to expedite the story in an hour-and-a-half. Crichton said he was having more fun and devoting more time to shooting the film than actually writing it, comparing the experience to playing cowboys and indians as a child. So, yes, Westworld is not much more than an adult fantasy with a number of plot holes that we are supposed to gleefully overlook, rather than analyze.
Except for blatant continuity mistakes you just invalidated every single entry on this site.
Suggested correction: Westworld ensure that any interactions with the robots are entirely safe for the patrons of the park. They cannot prevent humans fighting amongst themselves, just as Disneyland can't prevent people fighting there. People are also injured or die all the time in horse-riding accidents, but that won't lead to people suing Westworld. Due to the nature of the park, all the guests likely sign a waiver stating that any injuries are not the fault of the park.
Utter rubbish. Guests who were completely innocent bystanders could be killed or injured by the actions of other guests, notably in the bar brawl or by the explosion used in the jailbreak. We see one guest smash a barstool against the back of another guest - not a robot - which could easily have broken his spine. There is no question whatever that the owners and managers of the park would be held liable in this and many other cases, just as amusement park owners and managers nowadays are held liable when roller coasters or other rides go awry, injuring or killing guests.
The most plausible explanation would be a waiver that visitors to the park have to sign. The waiver would explain that while the robots cannot harm humans, other humans can, and the park is not held responsible. In the event of death or serious injury, the guest who caused it would face criminal charges and possibly a civil lawsuit. But a waiver would protect the park. Also, the rules of the park may be similar to those in the HBO Westworld series, where the robots cannot cause a "permanent mark", meaning they can injure guests as long as the injury is repairable.
Continuity mistake: In the British Museum, when Rick and Ardeth are saving Evie, Rick gives her a .45 pistol and they start to shoot the guards, her pistol fires once and the slide locks back meaning the pistol had no ammo, but she keeps firing as if the magazine was still full. (00:39:47)
Continuity mistake: During the infamous leg un-crossing scene when Sharon Stone is being interrogated, a cigarette in her hand disappears and then reappears.
Factual error: Based on the films being shown at the theater, the movie appears to be set in 1981. One of the TV commercials shows the Energizer Bunny, which didn't make its first appearance until 1988.
Plot hole: Why on earth would the military be interested in a soldier (sailor, aviator, whatever) who has to go into combat naked and unarmed, and who is detectable by an enemy equipped with a pair of cheap, mass-produced goggles? How would you treat them if they were injured? They would be utterly useless in any form of military operation, even espionage.
Suggested correction: Presumably the military are interested because Sebastian's research could lead to advanced forms of invisibility technology, such as the ability to turn materials and weapons invisible for use in combat.
You cannot second guess the film like that. Sebastian is making no effort to make non-living items invisible and throughout the film we see that is not possible (why else would Sebastian have to walk about naked?). His research is on animals (and later humans) not "materials and weapons" and is based on their physiology, anatomy and metabolism. How would you inject a rifle or a tank with a serum? They don't have a bloodstream. The military wouldn't see any value at all in this research - maybe they would be interested in invisibility, but not if it was restricted to living creatures as we see here.
You know how easy it would be for an invisible person to infiltrate an enemy's compound undetected and take out powerful leaders or dictators? Especially if no-one knew the technology existed.
Easy? Impossible. First, they would be naked and unarmed. Too bad if you are trying to knock off Vladimir Putin - a taekwondo black belt - with your bare hands during a Moscow winter! Being invisible doesn't mean you can avoid making a sound or triggering a pressure plate or an infrared detector and so on and so on. Final answer - a naked, unarmed combatant would be about as useful as a chocolate teapot in any form of operation, covert or otherwise.
Factual error: The hat that Brad Pitt wears in the 1985 scenes is a Padres hat with navy, orange and white as the colours. In 1985, the Padres' colors were brown and yellow. The color change didn't come until late 80's or early 90's.
Visible crew/equipment: At the end when Sidney's dad falls out of the closet, if you look closely you can see the hands of a crewmember who was in there too, pushing items out after him. (01:42:40)
Revealing mistake: There are supposed to be two dead young Asian males sitting in the back of the car, but in this shot, it is so obvious that there are two dead 'dummies' riding in the back. Also, in the crash, a few seconds later, very blatant dummy heads are flying everywhere. (00:40:40)
Other mistake: In the slaughterhouse scene, after Harrigan has injured the Predator with his shotgun and Keyes reappears, the Predator throws its disc, and severs Keyes in half at the waist. We see his legs flop to the ground, and blood pour from above, but his upper half (torso, backpack and weaponry) mysteriously remain hovering out of sight. (According to the director, the MPAA made him cut the footage of the top half of his body hitting the ground because it was too gory, creating this odd error). (01:21:50)
Suggested correction: We don't actually know if the disc completely cuts Keyes in half (or just passes through him and leaves a gaping hole). You see the blood, but the movie is edited so that it cuts back to Harrigan looking on in horror for a split-second, then back to Keyes' body on the floor (mostly obscured by a cement pillar).
They blatantly show his legs hitting the ground without the top half! I can only assume you watched an edited-for-TV version or something. It's VERY clear in the movie that he was cut in half. (In actuality, the scene was the victim of the MPAA according to the director... they had to cut the bit where the top half of his body hit the ground because it was too gory... creating this odd movie mistake).
Factual error: Towards the end of the film, Solomon is trapped in a small Plexiglas box and fires his gun into the bulletproof sides numerous times, but the bullets don't ricochet or get embedded in the glass.
Visible crew/equipment: When Mrs. Peacock turns on the cellar lights, a piece of lighting equipment is visible to the left of the screen. (00:47:45)
Character mistake: The last time Doc tries the defibrillator on Norris, he uses it on the abdomen instead of on the chest.
Continuity mistake: When Annie and Laurie leave the hardware store to go to their babysitting jobs it is broad daylight. When they reach the houses apparently just a few blocks away, it is already dark.
Continuity mistake: When Tim and Lex first arrive, Lex is wearing a purple tank top with a colorful design, and in the following scenes or even between consecutive shots her tank top changes to completely different designs, though it's the same style of tank top.
Suggested correction: The main character says he did quintuple his money four days in a row, not that he could continue to do so. "Presumably" he could do anything, like robbing a bank. Gambling is not a secure source of income, even with knowledge of the odds and every tell, he could also lose a lot of money.
