Factual error: Since the movie was set in the 60s, David Senak couldn't have gotten in trouble for shooting the man running away. In the 60s, the police could legally shoot any criminal running away. This didn't change until Tennessee v. Garner in 1985.
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: 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.

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.
