Factual error: A group of people are traveling in a pickup truck escaping earthquakes and volcanic eruptions. They come across a mist that they identify as sulphur dioxide, mainly by its smell and effects on people. Then the plastic interior of the car starts to melt, and they attribute it to the sulphur dioxide. Sulphur dioxide can attack plastics and rubber, but only in its liquid form. It turns gaseous at -10° C. After that it is a gas. So the melting of plastic is not correct at ambient temperature.
Continuity mistake: Man-seob smears some cream above his upper lip after a few smoke grenades are deployed. The amount of cream shown over his upper lip changes between shots.
Factual error: In the movie the professor's assistant says thst the professor was in OSS in the great war (WWI). OSS was first formed in 1941 by President Roosevelt.
Factual error: The musicians in the (real) Band of the Coldstream Guards that plays Happy Birthday for Christopher Robin are wearing their 21st-century uniforms and medals.
Other mistake: The Space Agency is trying to use an android mechanism (Human 2.0) to go to The Void and make first contact. Their first attempt at putting a human brain into the android fails. The solution is to make the android mechanism imprint human cells to facilitate the brain/android connection. The Agency is up against a time constraint, and someone comes up with the idea of using military Humans 2.0 to go on the voyage. Wait a minute! So now we learn there are other Humans 2.0 in existence? Wouldn't whoever made those already know how to solve the human brain/android interface? Why is the Space Agency reinventing the wheel?

Factual error: Emmanuelle Devos goes to the airport to get her husband and daughter. Their plane landed at 7 PM (18:58 to be precise) as shown by the airport monitor. They get a cab to a hotel downtown, and then there's a scene when she books a restaurant from the hotel room. She tells her husband, who just took a shower, that they need to be at the restaurant at 8 PM. Her husband says that there's no rush then, since it's only 7 PM. Of course that's impossible, the Turin airport is about 20km away from the part of the city they are driving through, which at that hour has also significant traffic; if their plane landed at 7, at 8 PM they would hardly have any time left to spare.

Factual error: Just after feeling the explosion from the south tower, Eddie's watch shows 17:37 whilst others and himself are stuck in the North tower elevator. The planes hit the towers in the morning. (00:35:00)
Continuity mistake: When Megan is outside the supermarket asking people to sign her petition, a woman walks up and begins writing on the clipboard. In the first shot, the cap is on the back side of the pen. From the next angle, the woman is scribbling and lifts the pen to show the cap covering the tip that she was "writing" with.
Factual error: The black leather chair of the Home trust banker is more modern than the movie setting in 1922. (00:59:35)
Continuity mistake: When the woman is sunbathing topless, the sun goes from being overhead in the far shots to in front of her in the closer shots. See also the difference in exposure.
Factual error: The scene with Queen Victoria in Florence happens too early since it is supposed to happen in the spring of 1888 but Abdul Karim was not yet her official "Munshi", being appointed to that title in August of the same year.
Continuity mistake: During the Memorial Day toast, Katie's hand is on and off the glass between shots. The level of wine in the glass also changes inconsistently. (00:12:20)

Factual error: Engine 463's firebox is seen in a close-up, revealing a cast in date mark of 1914. The caption near the start says it's set in 1892. (02:02:00)
Continuity mistake: Izzy gets out of the car of her one night stand and lights up a cigarette. She begins to type on her phone, phone in the left, cig in the right. A jogger bumps her and in the next shot she coughs on purpose to try and make her put the cigarette out. From now on, Izzy's phone is in her right hand and her cigarette in her left hand. (00:08:05)
Continuity mistake: Charlie was standing in the hole he dug and his head was below ground-level, but when Eliza was talking to him, Charlie's head was above-ground. Half of Charlie's back was above-ground when his mother [Toni Collette] was outside. Front views of Charlie standing in the hole still showed him against dirt (head below surface-level) even after he was just shown with his head above-ground. (00:51:10 - 00:51:46)
Factual error: At the end, it is stated that Mary was buried with her parents. Mary was not buried with her mother and father upon her death despite wanting that for herself.

Continuity mistake: The glass bowl of spaghetti is filled within about 2" from the top, but the mound in the center almost reaches the rim when Janice carries it to the table. After Tim serves at least 1 cup servings onto 4 plates, the bowl looks just as full as it is when Edwin leaves the table. (00:14:27 - 00:16:17)
Continuity mistake: Lynn Jackson collects things from the desk and looks at George Pierce, who tells her "I'll talk to him", clutching his smartphone to his chest. Next shot and his arm is down his side. (00:18:10)
