Character mistake: To compliment Xander Cage's physique, the overexcitable Becky tells him that he has 'guns' like 'the second terminator', specifying she means the 'liquid metal guy'. Robert Patrick surely didn't have 'big guns'. (00:29:40)
Character mistake: Toni Collette tells XXX that their plane has "Fuel tanks big enough to circumnavigate the globe three times without ever landing." The plane is a Boeing C-17 Globemaster III, which while having remarkable tanks, can go for 5,200 nautical miles, around 10 thousand km, 1/4 of circumnavigating it once. Even if someone made a tank 'big enough' to back the bragging of the snotty CIA boss, it would weigh so much that it'd be impossible to take off (and consume a lot more fuel too), which is why you can refuel that plane in the air.
Character mistake: The astute Xander Cage is able to guess that the fake tourist approaching him is, in fact, a fake because he spoke to him in English and he couldn't have guessed he was not a local. Of all the possible hints, given the fact that everything about a guy who randomly sits next to you and starts talking to you saying vaguely ominous things is suspicious, especially if you are a former CIA agent on the run, Xander's reasoning does not hold much water there when you consider that he was reading a map in English, with notes scribbled all over also in English. Anyone could have guessed that, and the guy takes a good look at the map, in fact comments on it. Besides, the tourist could have simply been looking for someone in this foreign country who'd knew his own language, and someone who has obviously been abroad a lot could be a good candidate for that.
