Factual error: Gorillas are almost exclusively herbivores. They have been observed eating small insects and grubs but nothing larger. So why does Isabelle eat a rat at the beginning of the film? The serum may have turned her into a crazed killer, as it does with Sebastian, but it hasn't changed the structure of her teeth and palate, biochemistry of her digestive system and so on, all of which would be required. She might kill or torture the rat, but she'd never eat it.
Suggested correction: This entry is wrong. Gorillas can, and do eat meat, so the actions of the gorilla are believable. From feedingnature.com: "Gorillas will sometimes eat meat. They can catch small animals such as mice, rats, or birds and will eat these animals if they lack protein in their diet. The silverback gorilla has been known to eat meat and might even attack and eat other primates." Even if you dispute this fact, most people would believe that a gorilla is certainly capable of eating a rat.
Suggested correction: Gorillas do sometimes eat meat, especially small animals. Also, Isabelle may not be getting fed the right foods resorting to her eating a rat. Humans will resort to drinking their own urine without access to water for a period of time, it's not far fetched that a gorilla will eat something that will be harmful to its body in a similar circumstance.
Gorillas do NOT eat rats. Inventing Deus Ex Machina explanations for a factual error (Isabelle was underfed so she was desperate for food!) does not invalidate the error. The posting needs a little more detail but is absolutely correct.
But she didn't eat it regardless so everyone is making the same mistake (she bit it, perhaps from the rage side effect?).
Nonsense. She picks up the rat, bites it in half, and swallows it. If she spat it out, we'd see it. As we see later in the film, anything ingested by an invisible creature instantly becomes invisible, so why don't we see a bloodied half rat splatter on the cage floor? Because Isabelle chewed it up and swallowed it.
Wild gorillas have been documented (on camera) feeding on freshly-killed monkeys. Like chimpanzees and humans, gorillas are omnivores and are perfectly capable of eating and digesting raw meat.
I think speculation about her eating it because she's not fed a proper diet isn't valid. But it's plausible the serum made her vicious where she ate the rat. To say her teeth and digestive system are the reason why she wouldn't/couldn't eat the rat isn't valid either. My dog once ate my sock despite not having the teeth or digestive system required to eat socks.
To add, it was noted that the gorilla's mind has been affected by being invisible for so long causing her to be more aggressive. Especially when she bit Matt's hand.
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.
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.
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).
Character mistake: When Ripley interfaces with Mother for the first time and sees the special order, an instruction reads as "Insure return of organism" rather than "Ensure return."
Character mistake: The last time Doc tries the defibrillator on Norris, he uses it on the abdomen instead of on the chest.
Factual error: Basic physics - Hancock throws Michel from a dead stop to above cloud level in about eleven seconds. The clouds are bog standard cumulus which form at around 7,000 metres in temperate zones. This means that Michel accelerates to about 700 metres per second instantly, from a dead stop. Obviously he cannot accelerate during his ascent, so his starting speed has to be at least that. (In fact he would have to start his ascent much, much faster than 700 metres per second as he would be constantly decelerating due to gravity and air resistance, but it will do as a start point.) Michel accelerates from 0 to 2,520 kilometres per hour - twice the speed of sound - in zero seconds. He would be accelerating at around 5000 Gs, turning him into a very long streak of fine, pink mist.
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: On the ferry, Rachel wears the purple/pink camouflage hoodie over her orange knit sweater with the colorful stripe sleeves, as usual. Now this is where things become strange. In the first shot as the trio come ashore, she is only wearing her orange sweater, she is not wearing the purple/pink hoodie - note the clear lack of fur hood. In the very next shot as they climb a bit more and then rest, Rachel is wearing the purple/pink hoodie - note the hood, but now it's on under her orange sweater. In the underwater shots she is also wearing it under the orange sweater. (This odd mistake has absolutely nothing to do with the very long wool cloak that Rachel wears in the next scene). (01:02:20 - 01:04:40)
Plot hole: At the end of the film Mardukas reveals that he has been wearing a body belt packed with cash - "in the neighbourhood of three hundred thousand dollars" - ever since Jack detained him in New York. Are we to assume that Jack Walsh, an experienced, hard-bitten ex-police officer, now a bounty hunter who routinely chases down violent and armed bail absconders who would kill him without a second thought, didn't even perform a perfunctory search of Mardukas when he detained him? This man used to work for the Mafia! What if he was carrying a weapon? A body belt with three hundred one thousand dollar bills in it would be uncovered by even the most casual pat down.
Factual error: The 15 bus in London does not go over Westminster Bridge.
Continuity mistake: When swimfan85 is trying to talk to Ben and he tells her he has homework to get done, she is talking with the nick name swimfan85 but when she signs off it says "swimfan has signed off." They forgot to add the 85.
Factual error: During the fight scene with Sandman in the armored car, the Terminal Tower can be seen in the background, which is a landmark in Cleveland, Ohio (where the scene was shot), not in New York City.
Continuity mistake: The T-1000 punches his body through the window of a helicopter to get inside. An instant later, the hole in the windshield is gone. (01:56:35)
Revealing mistake: When Dracula flies into the room to stop his brides from devouring Jonathan, the board carrying him is visible. (00:34:10)
Continuity mistake: He cuts a hole in her pants for insemination. When in the car moments before fighting the dog there is no hole.
Visible crew/equipment: After burning the car, when Dave takes the trash out there is a camera operator at the end of his driveway. (01:11:00)
Plot hole: Necros had absolutely no way of knowing that Bond and Saunders had arranged to meet at the cafe 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 cafe doors (or had planned this ahead of time - unlikely) and set the trap up well in advance of he 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.
