Will leaves the party at night with <2hrs left on his life, by morning, after driving far enough to outrun the cops/dragnet, fall into the ravine, get mugged for more time (having to split his time with Sylvia), walking to his friend's house, walking to a pawn shop that's about to close (5pm?), he still has a minute left. That's a lot of mileage in 2hrs! He should have died.
At the end of the film Will takes Raymond's per diem, yet when he splits it to save Sylvia he still has one day on his timer.
During the "arm wrestle" scene, despite the clear audio cue counting down the remaining seconds on Will's clock (down to 4 seconds), in the next shot there are still 10 seconds remaining on his clock.
After Will buys the Jag, he drives to the party along the coast road; you can clearly hear the V6 engine roaring and purring. After he escapes the time keepers and takes off from Weiss' mansion, you can hear it again. After the Timekeepers lose him and he gets away, however, his car is making the exact same 'futuristic electric/eco engine' noise as the other vehicles.
When Will is having breakfast at the hotel in New Greenwich, Sylvia is sitting a few tables away watching him. In the close-up shots of Sylvia, there is a guard standing directly behind her, but when the shot is zoomed out and viewed from behind Will, the guard is either standing at the table in front of Sylvia or behind the low glass wall behind her.
Will and Sylvia should have been ejected from the convertible Jaguar as they were not wearing their seat-belts.
Will's story about his father tricking his opponents by letting them drain his time makes no sense. Will says that they would be so focused on his father's timer that they wouldn't realize they are now losing their own time, but they would obviously notice this when they see his father's timer go up again. This would leave them with enough time to fight back. However, the point was not that looking at the opponent's watch would make them not notice, only that they would lose focus so that Salas could get the upper hand.
At the start of the film, the character Will Salas is seen getting out of bed and his time clock is on the left arm. Shortly after, he is seen looking through a window and when he turns to walk away, his time clock is on his right arm, switching back to the left arm after this scene.
The scene showing him turn away from the window is filmed in a mirror and therefore correctly reflects his left arm with the clock.
The pawn shop woman holding the shotgun has no time counter on her left arm.
When the E-type Jaguar crashes and is traveling inverted down the ditch, it is quite obviously a toy car.
During the car chase, the leading car is rammed in the back with the inside view showing the heads of the characters in the rammed car being knocked forward. This is physically incorrect as, in an accelerating collision, inertia would cause their heads to move backward relative to the car.
When the lead is being chased and a police roadblock is set up, the gauntlet is staggered so that the car can drive right through; there is no barrier at all. They are being shot at an angle with the front windows all open and not one bullet from the hail of machine gun fire makes it in.
In the beginning of the poker scene, the pot "clock" shows 600 years, and only 2 players remain out of the 4 players at the table. Yet when they show Philippe Weis time on his arm, it shows ~9860-51-6-00-02:09.
Since the arm timers can only go up to 9999-51-6-23-59:59 (13 digits), how did the pot get up to 600 years? Each player would have to have put in a MINIMUM of 150 years, which Mr. Weis could not have possibly done with "Table Stakes" as his timer is only a day less than 140 years from maximum.
Jaguar with Will and Sylvia loses control and crashes into ditch after all wheels are punctured by spikes. Hovewer after the crash it is clearly seen that all wheels are inflated as usual.
Sylvia correctly tells Will that Charles Darwin was born in 1809. This statement had to be dubbed because her mouth can be seen flubbing the line by saying 1804.
The casino across the street of Will's luxury hotel in New Greenwich is the Monte Carlo Casino, located in Monaco, Europe.
The time transfer ability appears to require conscious effort on the part of giver. People can think of a specific amount and it is granted. This would make sense in that people can't just run up and steal your time or accidentally trigger a transfer just by holding hands. This causes two problems.
First, when Wil and Sylvia crash, Fortis would not be able to steal Sylvia's time.
Second, the strong-arm contest would simply not work. At any point someone could just cancel the transfer.
Will did not get his deposit reimbursed going back to Dayton time zone (though it might be to discourage people going through).
If you drive a van through the glass window of a bank the massive steel vault does not just magically open.
When congratulating his mother with her 50th birthday Will says: "25 for the 25th time". However 25 for the 25th time would be her 49th birthday. On her 50th birthday she turns 25 for the 26th time.
Rachel's decision to pay a 2-day loan and leave herself with only one and a half hours, one hour of which would have been spent if the bus fare had still cost that much, is far too reckless for someone who managed to survive to 50.
Wil is shown to be both intelligent and possess a lot of street smarts. He would know better than to give his alcoholic friend so much time unsupervised.
