Continuity mistake: When the gang bids a silent farewell to Xander, look at Nicks in his close-up; in the background, Tennyson Torch is turning around towards his right, but in his own close-up, Tennyson turns towards his left, and Becky is close to him while she was nowhere in sight before. (01:33:10)
Visible crew/equipment: During Gibbons' funeral, when the camera pans up to eventually catch Vin Diesel sitting in the gallery, a few extras (such as the woman two rows behind the one with the flaming red hair) look up following the movement of the crane. (01:36:10)
Factual error: When Xander Cage is chasing Xiang on the dirt bikes, he lets his bike get entirely submerged, which would flood the engine.
Continuity mistake: When we see Serena for the 1st time leaning against the column she is wearing high heeled black boots. Later when she is on the beach after Xander took Pandora's Box, she is wearing low square heeled boots.
Continuity mistake: Just before Ruby Rose spins down from her sniper shot, it's still night time. As she comes down it's suddenly much brighter, and very seconds later as the chase continues, it's broad daylight.
Plot hole: Ice Cube's cameo is really neat for the fans of the series, but does not make a lick of sense. Brushing aside the fact that the fangirl knows who he is when in theory his involvement in XXX 2 was never officially sanctioned and he gets no mention, presidential pardon or anything in his own movie, the fact that dialing 9 he just shows up in the space of minutes in Detroit with no reason for him to be there is nothing short of supernatural.
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.
