Revealing mistakes
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.

Incorrectly regarded as goofs
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.

Continuity
During the car chase scene, as the car is rammed and begins to spin out of control, during the spinning, the pursuing police car is nowhere to be seen despite the 360 degree camera pan. It then re-appears when the car ceases to spin.

Revealing mistakes
After the car is hit by the stinger trap and plummets down the embankment, there are clearly no people in the vehicle as it falls.

Continuity
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.

Revealing mistakes
When the E-type Jaguar crashes and is traveling inverted down the ditch, it is quite obviously a toy car.

Continuity
When the two main characters are sitting in the stolen limo under a tree, the opening shot has them facing the sun, but while watching TV, in the back seat the sun is over Salas's right shoulder.

Revealing mistakes
The rear view mirror has been removed from the car that Will purchases.

Errors made by characters
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.

Audio/visual unsynchronized
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.

Revealing mistakes
The pawn shop woman holding the shotgun has no time counter on her left arm.

Continuity
In the poker scene Will is seen to pick up a glass of champagne with his right hand. Less than 2 seconds later he is shown to be playing with his chips with his right hand.

Warning: Spoilers
Goofs below here contain information that may give away important plot points. You may not want to read any further if you've not already seen this title.

Plot holes
When Rachel goes to get the bus to meet Will, she expected the cost to be an hour and had an hour and a half remaining. The bus journey must have been less than half an hour if it was to get her there in time. The distance was said to be a two hour walk. Will heads back towards Rachel when the bus arrived without her. If Rachel starts walking when the bus leaves and Will starts walking towards her half an hour later they will meet after one hour and fifteen minutes and she will have fifteen minutes left.

Continuity
When Henry Hamilton is sitting on the bridge, there is no water in the drain below him. When he times out, there is water flowing through it.

Continuity
Near the end of the film, when Will drives through a hail of police gunfire at a roadblock, the bulletproof window on the driver's side is down. A few seconds later, it is up, showing at least three marks where where bullets supposedly bounced off the glass.

Continuity
When Will looks out the window and sees Henry sitting on the railing, Will is forward, and to Henry's left. Yet when he runs to the bridge to try to give Henry more time so he won't die, Will runs up from Henry's right. This means Will either ran left out of his building to another bridge off in the distance, then back to Henry's bridge, or he ran across the water flowing in the drain without getting wet, across the railroad tracks, and up the incline to run across Henry's bridge - all in less than a minute, going by the time we see on Henry's arm.

Continuity
In several scenes where Will and Sylvia are running, the heels of Sylvia's shoes shrink and grow in between shots. Most notably in the final scene where she runs into Will's arms her heels are several inches taller when she stands up than they were just seconds before. The strap on the shorter shoes is also further down the foot than the on the taller ones.

Continuity
After Henry gives Will all but five minutes of his own time, Will wakes up to see he has a bit over 116 years on his clock. He then gives a decade to his friend, buys some flowers for his Mom, spends years, as the timekeeper says, crossing time zones, and then gets a suit in a fancy hotel. Yet when he wakes up the next morning his clock still reads a little over 105 years.
