Factual error: During the bike chase, Henry is able to neutralize the first bike that Junior is riding. The bike falls down and explodes inches to the right of Henry's, who is riding at top speed, and is completely unfazed by it, does not even wobble. (00:39:15)

Continuity mistake: Junior confronts his fake dad in his office. Clay puts his glasses down and they are initially on a sheet of paper by his keyboard. But in a closer angle after junior names "The lab guys who made me" the glasses have changed position, being on the desk by the folder Clay Verris was working on with his awkward typing. (01:18:00)

Continuity mistake: The first time we see Baron there is a little introductory dialogue with him. At the end he ask for one of Danny's (expired) crackers. He then turns around and her right hand rises to pick a new one - but in the next shot she is holding the box with that hand and the cracker is in her left. (00:27:55)

Continuity mistake: Will Smith and Mary Elizabeth Winstead react to the explosion of the van with different speed between shots. From behind, she raises her arms first, but in the frontal view her reaction is delayed compared to Smith's. (01:27:55)

Continuity mistake: When Will Smith's clone decides to try and kill him by beating him up with his bike, the shadows next to the car change wildly; it is particularly obvious when the middle-aged one springs into air from lying down on his belly into a huge shadow that just was not there. (00:40:40)

Continuity mistake: The morning after escaping from Brogan's house, Danny is eating some crackers. In the first shot she passes the box from her left hand to the right, in the next, Brogan points out that they are long expired while she is holding the box still in the left hand and a new cracker in the right. (00:22:50)

Continuity mistake: Henry shoots the tire of a car to slow down his pursuing clone. Junior is trying to pass the car to the right as it sways out of control.The zone of asphalt he is speeding through is in the shadow, but at the next cut, when he actually manages to pass in ridiculous fashion, the road is uniformly lit. (00:40:00)

Revealing mistake: During the drill that follows Junior's return 'home' in Georgia, the extras who flee from the building and run in the street split in two, left and right of the camera position (one guy even slows down his run quite obviously to avoid tripping the offscreen equipment). (00:48:30)

Sammo ★

Stupidity: Spoiler. In a typical 'why didn't he do it before?' twist that kinda invalidates the rest of the movie, it turns out that the villain has had a third Will Smith clone all along, ready for deployment in Yemen and with fear and pain genetically removed, ready to blindly kill anyone, combined with so much body armor that even point blank AR-15 carbine shots barely faze...but he sent the 'prototype' he raised like a son instead, in a hoodie and baseball cap.

Revealing mistake: Henry is being chased by Junior on his second bike. In a POV shot as Junior crosses the bridge, you can see he is dodged by a guy wearing a yellow baseball bat and a red Hawaiian shirt. Only, in the reverse angle (the bike coming out of the bridge) the cap stays yellow but the shirt turned inexplicably grey. (00:39:30)

Sammo ★

Continuity mistake: When Junior takes a swing at his 'dad' with the rear of his bike sending him flying against the car, notice how at the beginning of the shot with the camera positioned overhead the side mirror is folded, either to make the stunt easier or because during some take it was knocked back that way. The same mirror is in its normal outwards position in the rest of the scene. (00:40:50)

Sammo ★

Continuity mistake: On his second bike, Junior passes a bridge, cuts a corner with an acrobatic jump and begins chasing Henry through a second bridge, longer, wider and crowded with people with hats and shirts.The position of a few of those guys (like the one with the green shirt) doesn't match between POV and reverse. (00:39:40)

Sammo ★

Continuity mistake: At the culmination of his bike-fu Young Will Smith torpedoes the motorcycles at his older self; the move initiates with a wind-up time marked by a huge skidmark on the asphalt. But in the next shot there's no mark, and the kamikaze run starts from a different point. (00:41:25)

Sammo ★

Stupidity: Despite the fact that the villains know exactly where Brogan is for the better part of the movie thanks to a tracer, and that they display constantly that they are able and willing to hit with bold military operations even to the point of hitting an urban area overruling law enforcement (apparently Clay has authority to do that too), Brogan is able to get undisturbed back in the US through his friend's plane. Considering he was officially marked as a rogue agent and killed 8 DIA operatives, it's hard to see how Baron's plane could ever land on American soil after a long intercontinental flight.

Sammo ★

Plot hole: Apparently, in 20 years Junior and his dad never once discussed the subject of his birthday, aka "If I am an orphan, how do we know when my birthday is." It is something that can have so many perfectly innocent explanations that Junior can't verify ("It's the day I found you" being one) that would be tremendously odd and inconsiderate of the manipulative villain to not even have conceived a shred of a back story for it (in fact he should have been the one feeding it to him first at a young age). (01:18:00)

Continuity mistake: In the movie ending, the three main characters (and two main actors) are walking off together following Will Smith Sr. That 'knows a place' to eat. Notice on the left part of the frame, along the path they are traveling, a couple of students; he has a beige jacket, yellow-ish sneakers and jeans, she has a blue jacket, and they are talking with another girl with a lighter blue jacket. In the next shot Danny asks him "So you settled down on major yet?" and the two aforementioned students are behind them, standing at the beginning of the walkway. (01:45:35)

Plot hole: The villain is hellbent on killing Henry, or his secret cloning project may be exposed. His 'son' Junior fails to kill Henry in Hungary in a train of events starting at midnight, local time, and that takes at least an hour between action and mundane offscreen necessities like flight preparations. He then shows up in his office in Georgia to inform him of his failure. It was a flight over 8,000 kms long; let's factor in the 6 hours time difference between Budapest and the EST and assume he took off right away; his dad is at the office at 3 or 4 AM, unsuspecting and quietly doing other work apparently unrelated to the most important matter his whole business hinges on, not a worry about Brogan being obviously not dead (he knows where he is due to the chip). And there is enough time left in the night for all the big climax of the movie to happen, including mobilizing a large force for urban combat without a soul in the streets.

Plot hole: Mending the wounds Junior received in the Colombian mission, Clay asks him "Did you get a look at his face?" And Junior replies "Not really. I saw him at the stairs through a dirty mirror." First big issue; do we have to believe that the guy was sent to kill Henry without knowing how he looks? We do learn later in the movie that Henry has been chipped, but Junior is stalking him as a sniper/hunter and is not using a HUD to track him. Plus, the movie explicitly negated it earlier; Henry himself in Cartagena asked Junior "Did they show you a picture of me?" to which he replied "Yeah, you look old." So Clay's question is really odd and suspect (if anything draws attention on something he should be trying to hide). Second problem; Junior fought Henry in a close-up fight at the end of the chase, the mirror bit was not their only encounter! Why would he lie to his supposed father, especially when he is trying to get answers from him? (00:47:00)

Sammo ★

Continuity mistake: At the traffic lights, Junior receives a 'call' through his ear bud from Clay Verris. In close-up the young Will Smith has his raised hand with his fingers curled, but in the next shot they have straightened up some. (01:27:10)

Sammo ★

Continuity mistake: Junior's DNA-laden baseball hat changes position on the ground the first two times it is shown, slightly, and it is in a different spot where big slabs of asphalt meet as Danny retrieves it. (00:41:30)
