In Time

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 Will is escaping after being chased from the party, he drives over a 'stinger' which causes him to lose control of the car and crash.

'Stingers' don't do this.

they are designed to let the air out of tires slowly and bring the car to a safe stop.

This is why the police use them.

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.

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.

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.

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.

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.

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.

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

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.

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

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.

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.

As Sylvia gives Will the combination to her father's safe, she audibly gives him Darwin's birthday ending in 1809.

Visually, you can see her mouth as she says, ".

1804, right?" 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.

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.

None of the cars in the movie have license-plates.

- PLOTIf none of the cars have license-plates, how are the cops able to tell which car Will is driving? Everyone in the movie has their clock on their left arm.

However, when Will and Sylvia are at the pawn shop, the woman holding the shotgun has no clock on her left arm.
