Visible crew/equipment: A reflector screen is visible on Hawkeye's sunglasses at the very end when Thor and a restrained Loki are returning, presumably, to Asgard. (02:06:10)

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.

Continuity mistake: In the beginning scenes, where Milo Thatch is practising his proposal, he slides over (face forward, chest against the board) a chalk drawing of a map detailing the location of Atlantis. When he realises he wiped off the drawing, and sees it on his clothes, he stands in front of the blank part of the chalkboard, "filling in" the space with the map that rubbed off on his shirt - the only problem is, that the image should have rubbed off backwards as he was facing the board when it transferred to his clothes. He could not simply stand in the place of the missing map face forward and have it read properly.

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)

Plot hole: When the group is walking through the jungle for the 2nd time, they have nothing more than their backpacks and a horse to accompany them. Suddenly we see them rowing down a river on a boat and raft. After making peace with the savages, when they have to let a group member go to get medical help, they have been washed ashore as they have been traveling on a single raft since the canoe was damaged by spear attack. How is it that they had a horse and an Indian guide to send away with their injured man? (01:16:55)

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.

Other mistake: When the Japanese planes take off for Pearl Harbor, some of the 3 man torpedo planes only have a pilot.

Factual error: Rob Base and DJ E-Z Rock's "It Takes Two" was not released until 1988. This movie takes place in 1987.

Factual error: An An-12, the aircraft the main character uses to fly all over the world, has a maximum range of about 3,500 miles. Hardly enough to fly from the US to South Korea or from South Korea to Israel. The An-12 also miraculously transforms into a C-130 in a couple of filler scenes. And why is this ex-Soviet aircraft marked in USAF markings, assigned to McGuire AFB?
Suggested correction: Can't speak to the second half of your paragraph (should really post as 3 separate mistakes) but as for the first, a range of 3500 miles, aircraft such as the kc-135 exist and aerial refueling is fairly common place. Considering it's a mission supported by the acting UN Secretary General to stop a world crisis, resources could have been diverted for refueling.
The initial launch from the carrier is a C-130 which can do this (if empty, minimal fuel, has the full length of the flight deck and the carrier is steaming full ahead into the wind). It then morphs into an AN-12 and back to a Hercules. They make the point that this small fleet is what is known to remain of allied forces so not sure where any tanker support will come from. Many movies have ridiculous range issues with aircraft anyway.

Continuity mistake: After being chased by soldiers after talking to his uncle, Dastan gets into a swordfight with Garsiv. As soon as it starts, Garsiv hits a pillar with his weapon knocking a significantly large chunk and a another smaller chunk out of it. In the immediate shot, the size and locations of the two chunks differ.

Revealing mistake: When the team descends to the bottom of a hole and one female member is first wounded and then dies. After checking her pulse, the others pronounce her dead and begin moving out. As the last one is leaving, the "dead" actress lifts her head up off the ground and looks left. (01:13:10)

Continuity mistake: When the two female characters enter the fancy hotel room, they make a point to say they will only be there for a couple of minutes. It is daylight when they go in. The visit is cut short (the one that's supposed to be a few minutes long) because of a gun battle in which one of the women dies and the other escapes. The escaped one gets out through the roof into an evening's sky. There's still light visible, but for a visit that lasts all of 4 minutes, it's far too quick a change. (00:23:00)

Continuity mistake: When Johnny Cage is fighting Scorpion, and he does his human spear, Johnny runs until he stops at the tree. The spear then catches up, and becomes wrapped around the tree in front of Johnny. When the camera changes view, the spear is just leaning on the tree. The camera changes view again and the spear is wrapped around the tree again. When Scorpion pulls the spear back, it goes straight back, and doesn't unwind around the tree.

Plot hole: Harry tells Doc Ock that in order to find Spider-Man he must find Peter first. Doc Ock finds Peter with Mary Jane in the cafe and throws a car through the window straight at them, then later throws Peter against a brick wall. Any normal person would've been killed instantly (or very badly injured), and Doc Ock doesn't yet know that Peter is Spider-Man. Given that Peter is his only lead on Spider-Man, it makes no sense that Doc Ock would try to kill him.
Suggested correction: Doc Ock is being controlled by the arms. They aren't behaving rationally.
Creating a series of silly explanations for obvious plot holes never resolves them. These arms were not behaving irrationally. In many scenes they were shown to be very intelligent. A good example is the scene where they attack doctors who try to remove them from Doc Ock's body. Saying that they weren't behaving rationally is absurd.
He may not have been trying to kill Peter, he could've been trying to make more of a scene of his entry, so Peter would take him more seriously and tell him where Spider-Man was. He could've been thinking of it as a risk of killing Peter though, but his arms made him go crazy.
This is only a theory. Theories never resolve mistakes.
It's not a theory. When Otto is first giving his demonstration to everybody at his apartment, a woman asks if the advanced AI for the tentacles would make him susceptible to being controlled. Otto says that yes it would so he shows everybody the inhibitor chip that he designed so he would not fall under its control. After the inhibitor chip gets destroyed, it's seen that the tentacles have not only taken control of his mind by forcing him to commit crimes, but have slowly driven him insane.
This scene is much too confusing for many people. This entry is correct. This is a mistake.
If these tentacles wanted him to finish the experiment then they wouldn't make him kill the person who has valuable information for him.
The arms are influencing his thoughts but not controlling every part of him. Doc Ock still seems to have control when defending himself but they seem to work in tandem with Ock. The only time they work on their own is when he under anesthetic. As we don't see him before he throws the car, we can only speculate the arms were trying to hurt Peter by themselves.
It's a cool scene regardless man.
Killing Peter would probably send a message to Spider-Man as well, so Ock probably wasn't concerned about being gentle.

Visible crew/equipment: When the Kurgan is fighting Ramerez he hits the wall and stones fall on him. A crew member can be seen pushing the stones out. (00:56:35)

Visible crew/equipment: After the Terminator arrives in 1984, he begins to walk over to a short concrete wall and looks at Los Angeles over it. A second before the shot ends, the shadow of a camera is visible to the left of screen. (00:05:05)

Factual error: Before receiving the North American P-51D Mustangs, the Red Tail squadron was using the Curtiss P-40E Warhawk. The movie shows the Warhawks being able to keep up with the German Bf 109 G-6s quite easily, fighting on even terms. In reality, the Bf 109 G-6 could easily outperform the Warhawk, being able to easily outrun and out-turn the Warhawk. Still, the Bf 109s are no match for the Warhawks.

Continuity mistake: When Nick is sitting on the bed talking to Jessica, her position changes from lying on her side to lying on her back, as the camera angle changes.

Revealing mistake: When Mr Witt rides out of the Zulu camp in a 2 horse cart at the beginning of the movie, just before it exits, you can see it's a stunt double at the reins.

Factual error: When it's 00:00 on January 1st, it's not night in Sydney, it's 11 AM. When they 'reveal' stuff at the end of the movie, and they show that things happen exactly at 00:00 in the night in London, it can't possibly be dark in Sydney, Australia.
