When Loki and Thor first meet up on Sakaar, Loki reveals that he's been there for weeks and yet despite this, Loki is somehow completely unaware that Hulk is also on Sakaar as shown by his reaction in the battle arena. This seems incredibly unlikely considering that not only is Hulk a huge celebrity there, but also that Loki had gotten in good graces with the Grandmaster. Surely he would have found out who the champion is. His likeness is even featured atop the Grandmaster's tower.

When Nick is finally invited to the party, he tries to find Gatsby but is told by several party-goers that no one has ever seen him and they don't know if he actually exists. Later in the movie,there are flashbacks of newspapers with front page stories of Gatsby buying up New York with several showing his picture as part of the article.

The downstairs assumes that Marty is killed by Judah Buckner. However, an earlier shot shows that the downstairs is monitoring everybody's vitals, so they should have known that Marty survived the attack.

Nobody brings up the idea of injecting Phoenix with the cure, which would be a way to stop her without killing her.

Edward is seen making various ice sculptures. Where does he get the ice from?

For the most part of the movie, Francis behaves like not feeling any pain equaled invulnerable. The injuries he suffers during the plot (like the motorcycle crash, or the blade stabbed in this leg, not to mention the container hitting him) should have a serious effect on his mobility even if he can't feel them happening.

Earlier in the movie, a comment is made that all of the animals are 'fitted' with a device to shock them in submission if they escape from their paddock [the device fails on the Pachycephalosaurus because their butting heads short-circuits the device]. When the flying dinosaurs escape from the aviary, the device should have stunned all of them as they flew from the enclosure. Or, the humans back in the control room should have activated the device to stun the creatures instead of watching them attack the crowds.

Dr. Gordon was the police's initial suspect in the Jigsaw killings. Yet it never occurred to them that these killings took a huge amount of time to plan, setup and execute, so a surgeon who is constantly working doesn't make sense as a suspect. The devices had to be custom built, the killing rooms configured and clues planed and hidden, the victims were under surveillance for weeks. So doing all of this required hundreds of hours. Dr. Gordon is an oncologist and a neurosurgeon, a doctor with dual specialties like this often works 90-100 hours a week easily so most of his whereabouts during the day would have been known by his coworkers. While it's possible that some of the work could have been done at night he certainly wasn't able to survey the victims at night, plus if he was frequently staying up all night to do all of this it would have shown in his surgical skills, his ability to perform surgery would have been severely diminished if he was suffering from sleep deprivation. Dr. Gordon made no sense at all as a suspect, which is something an experienced homicide detective would have realized right away.

Victoria is seen twice in the last scenes (at prom). In different parts of the movie it is shown that Edward can hear thoughts from great distances and in loud places. Thus, in these last scenes, Edward should have been able to hear Victoria's thoughts and should have acted on that.

Sam is regarded as a music fanatic, particularly in regards to artists belonging to the glam and new wave genres. Anyone with any significant exposure to this music would undoubtedly recognize a David Bowie song by his voice alone. It is not believable that it would have taken Sam more than a school year to identify the tunnel song as David Bowie's "Heroes."

In "Be Our Guest", Lumiere explains that the castle's residents "Have been rusting for ten years", which would imply that the twenty-one-year-old Beast was eleven years old when he was cursed (which contradicts his torn portrait in the West Wing).

Snow White is wakened by a true love's kiss from the Huntsman, yet there was never any hint of romance between them. In the sequel it is shown that the Huntsman's true love was his wife.

In a scene where a policeman shows up to pick up Kevin and bring him to his family, he kept knocking until he decided no one was home. In reality, a policeman wouldn't think no one is home when Kevin was in the house as they would actually get him to get out of the house so that they could bring him to his family.

Through official canon, the atmosphere of Pandora is toxic to humans due to the presence of Hydrogen Sulfide, a very potent toxin in even small amounts. Jake Sully is exposed to the Pandoran atmosphere for several minutes, long enough to cause complete respiratory shutdown. At this point, the effects of this exposure would not be reversed by simply donning an exopack.

The entire movie is about trying to stop Trask from acquiring Mystique's blood, and giving the Sentinels the ability to use mutant powers. However, Mystique can only imitate the appearance, and sometimes voice, of someone else. They would have to get Rogue's ability instead as she absorbs and obtains other mutants' powers.

If the twelve tribes of the Medjai number in the thousands, why weren't they able to stop the excavation of Hamunaptra in the first place?

Watney claims that nothing sent on the mission will burn, which is why he has to destroy the crucifix which Martinez had in his personal items. Yet Watney is often shown writing on paper in the Hab and paper, obviously, burns.

When the group goes into the parking garage to turn on the generators they never make it. They are instead confronted by zombies who they douse with gasoline from a pump and set on fire. If there was no electricity in the garage then the gasoline pump wouldn't work.

Earth is shown to be a desert planet with the oceans and such dried up, yet there is a torrential downpour rainfall.

Since Senator Kelly died in the middle of X-Men, his subsequent appearances have been impersonations by Mystique. But any U.S. Senator's personal and political obligations occupy nearly every hour of each day. Given that there is only one Mystique, and that she impersonates several other characters in addition to appearing as herself, "Senator Kelly" must frequently disappear for hours or days at a time. In the real world or even the comic book world, her intermittent use of Kelly's likeness would be quickly uncovered as bogus by his family or staff.

For reasons unknown, the monkeys, buzzards, bees and little fox-like creatures are the only animals that do not speak at all.

If Bilbo ages rapidly without the Ring, why hasn't Gollum suffered the same effect?

Before Ethan jumps into the cooling system, he's told that the system can detect metal. Hence, he cannot bring in oxygen tanks. We see Ethan inside the system wearing a sleeve with a computer-based screen showing his vital signs. This screen and computer would not be possible without metal.

The rebels cannot jump to light speed because the First Order can track them, but the First Order cannot catch up to them, they can only keep pace. But, it would be a simple matter for the First Order to have a couple ships go to light speed a short distance and immediately return just ahead of the rebels. The First Order could easily and quickly destroy the Rebels with this simple tactic. The resistance would have been trapped in a flanking attack and overpowered by the First Order.

When Ennis receives Jack's first postcard it's sent general delivery because Jack didn't know Ennis's address. When Ennis writes back all he says is, "You bet," and leaves no return address, thus Jack still doesn't know where he lives (just the town). In the next scene Jack arrives at Ennis's apartment without this vital information.

At the end of Rocky IV, Rocky's son (born in 1976) is 9. However, at the beginning of Rocky V, which in the movie's time-line takes place only a week after the end of Rocky IV, the boy is already 12 or 13. In addition, Rocky IV is set in 1985 (we know this because it is nearly the 9-year anniversary of Rocky and Adrian, and they were married in 1976), yet in this movie, Rocky Jr. and his friends are watching the 1989 movie National Lampoon's Christmas Vacation.

It is stated that aliens make people forget their sight of them every time they make contact and even repair whatever is destroyed in minutes. But, since Jupiter's phone kept the photograph of the aliens she saw even though they erased her memory, how come nobody took a photograph of the battle in the city skies and thus kept a non-erased proof of their existence?
