Plot hole: In the last car-chasing scene, the timekeeper had switched his car to chase them, then how could Justin Timberlake get the timekeeper's salary (a day's time) from a car that the timekeeper picked up from the streets?
Suggested correction: I think it is the car of another time keeper. Hence, it may have a time transfer system.
Other mistake: Will did not have enough time to place into the pot at the poker game. For those at the end of a hand, they each have contributed a minimum of an equal percent based on the number of people in the hand. There were potentially 5 people at the start of the hand, and Will did not have enough to cover 20% of the final pot. He would have needed well over 200 years available, and we know he had a little over 100.
Suggested correction: It's suggested that Will was at the table for a while, and we, the viewers, return later to see the stakes have increased. This is established when the camera shows his wrist as having over 250 years available, when he entered with barely over 100.
Continuity mistake: When Sylvia shoots Timekeeper Leon, the S&W 945 in her hand has a magazine inserted into it. But in the next shot where she quivers and rushes over, the magazine is gone.
Continuity mistake: Justin Timberlake drives over a spike strip which leads to losing control of his car and falling into the LA River under the 105 Freeway bridge. After Timberlake and Amanda Seyfried awaken, Amanda walks away from the wreckage and the tires on the wrecked car are still fully inflated and supporting the weight of the car. (00:50:00)
Other mistake: At the end of the film, as Will and Sylvia run from the time mission after giving away the million years, they run out of downtown and towards the border of the Zone. Raymond drives to that border, gets out of his car and runs towards them. The area is a desolate, empty road, with no buildings or other obstructions to the view - one can see miles across the landscape - yet Will and Sylvia don't see Raymond running towards them until they are within 50 feet of each other. (01:33:55)
Continuity mistake: Toward the end of the movie, when Timberlake and the girl are running on the empty road, her shoes keep changing between pumps and sandals.
Continuity mistake: After Fortis loses the time fight and dies, Will takes Sylvia by the right hand and starts running dragging her after him. In the next frame, Sylvia drags him.
Continuity mistake: Toward the end of the movie, after the TimeKeeper dies and Timberlake and the girl start running toward the TimeKeeper's car for more minutes, in the background, as they are running, the TimeKeeper's body has vanished.
Continuity mistake: When Henry Hamilton dies his body falls directly down from the bridge, but when Will sees him from that same point on the bridge, the body is now roughly 50 feet from the base of the bridge. Additionally, his body splashes, and then 'bounces' back up, as if the river were at least several feet deep - but when Will looks down, Henry's body is in mere inches of water. And the current was flowing towards the bridge when he fell, but when Will looks down, it's flowing in the opposite direction.
Continuity mistake: When Will escapes the party with Sylvia as hostage, he barely avoids an accident with an armoured car, into which the Timekeeper Raymond crashes. As Will leaves the scene, he is driving on the left side of the road. The camera shifts to Raymond for a moment, then back to a rear view of Will's car, now driving on the right. The camera angle changes again, and he is once again driving on the left. The right is the 'correct' side of the road, evidenced by all the traffic around them.
Continuity mistake: When Timberlake is escaping in his new car being chased by the timekeepers, they are driving along a busy bridge, swerving in and out of heavy traffic. After the timekeeper crashes into the truck, Timberlake then drives off with no traffic in sight.
Continuity mistake: In the scene where Will is eating at the hotel, Sylvia is in the background. Several times her position changes oddly, but a second or two between shots technically makes the changes feasible, if implausible. Towards the end of the scene, though, between angles her position changes from her head looking down, with her bodyguard 10 feet away, to her head straightened and the bodyguard beside her.
Continuity mistake: When the Timekeepers Police car is sideswiped by the truck, you can see the drivers door bursts open, and the panelling where the door would latch onto to close is dented severely which would prevent the door closing again, but when the camera cuts to an inside shot of the car, the door is shut as if there is no damage.
Revealing mistake: When Wil is showing Sylvia how to shoot, and she fires, Justin Timberlake can be seen wearing earplugs. When the scene cuts, he no longer is wearing them.
Continuity mistake: When Will Salas is being chased by the time keeper near the end of the movie Will crosses from time zone 12 to time zone 13. At the end of the movie when Timekeeper Jaeger is looking at the map there are only 12 time zones. (01:35:30 - 01:41:48)
Continuity mistake: When the car crashes after hitting the spikes, the amount of damage sustained doesn't match what we see happen. Then once the car has stopped moving, damage appears in areas that didn't even get damaged.
Continuity mistake: When Henry and Will are settling down for the night, Henry passes Will the hip flask again with the lid closed. When Will takes it the lid is open. (00:14:10)
Continuity mistake: SPOILER ALERT: When Henry Hamilton is first visible through the window by Will Salas he is sitting on the bridge and located on the very center. This bridge is the 7th Street Bridge in Los Angeles, which is a three arch viaduct design. After Will runs outside the building, the camera cuts back to shot of Henry, who is now sitting over the west bank of the river. The next shot, Will is directly in front of an electrical utility tower which obviously would never be placed over the center of the river. Then a closeup with Will's feet visible where you also can see the east-side arch and that he is still sitting over the west side arch of the bridge. Then when Will falls off the bridge he is back over the center arch of the bridge. It's most likely that the movie crew needed to relocate "Henry" to the west side in order for a camera boom to reach him for the close-up shot from the ground. (00:16:00 - 00:17:00)
Factual error: Spoiler alert - When Henry's body is recovered under the 4th Street Bridge in Los Angeles, the 6th street bridge and the 7th street bridge (the one that he fell off) are each visible in the background. Meanwhile the water is visible moving towards the 7th street bridge which indicates that his corpse floated against the current. (00:22:20)
Continuity mistake: When Will and Sylvia's car hits the stingers (spike strips) that blow out the tires, they are driving on the 'right' side of the road. Off the edge of the right side is a grassy area. Will veers to the right trying to stay in control, then the camera angle changes, and we see he is on the other side of the road veering left, where the concrete river is. The camera angle changes, and they are back on the right side, just before another angle change where they fly over the edge... Of the left side. Perhaps there was originally a wide shot showing the car veering way across the road and back; but in the final edit, what we see is a big continuity mistake. (00:46:15)
