Goofs

(at around 1h 25 mins) When Damian crashes Martin's SUV into the car in front, the airbags of the SUV (as seen from a long distance shot) clearly inflate. On the next shot from inside the car, Damian is still driving with no airbags inflated.

While talking to Anna at the edge of the fountain at Martin's house, Damian's watch can be seen skipping back and forth during the conversation between 7:30 and 8:00.

At the start of the chase from Martin's house, the driver's side window is down, but it's suddenly rolled up the next instant.

When young Damian comes to Madeline's house, he pushes the door open completely and calls out "Hello?" In the next scene, while Damian is getting in, the door is not even half-way open.

At Madeline's house, the bullet hole in the bathroom door changes, not position, but to the point of it seemingly not being there at all.

Albright says the room was built to withstand a lot of radiation. When using magnets, no radiation is released so there is no need for this. Also, lead lined glass used for shielding radiation is incredibly delicate and could not be bulletproof.

The main characters find a Wikipedia biography for "Dr. Francis Jensen". Wikipedia biographical articles do not allow professional prefixes or suffixes in their titles; it should have just been named Francis Jensen.

Early on, it is revealed that the mirror in the transfer chamber is actually a two-way mirror. Upon turning on the light on the inside, the mirror gets transparent. The flamethrower in the finale should have been light source enough to reveal what was going on inside.

The reverse-engineered pill recipe consists of a number of antiepileptic medications but contains spelling mistakes (e.g. Valporic acid instead of valproic acid).

One may question when St. Louis started building levees. The levee was shot in the New Orleans area, but the mistake was showing the levee during the water tower scene. There are 89 levees in the St. Louis district...compromising more than 700 miles of structures. (U.S. Army Corps of Engineers St. Louis District Website.)

The active ingredients in the pill recipe add up to only 90% and not 100%. 25%+30%+15%+15%+5%=90%. This is incorrectly regarded as a goof as most pills contain a percentage of inactive ingredients, called excipients, often making up even more than 10% of the composition. Furthermore, as this is a reverse-engineered recipe, it may simply reflect an inability to identify the remainder 10% of the original formulation.

When Damian awakens in his new body, his British accent has mysteriously disappeared with no explanation. Yes, there are some traces left of the body's former American owner Mark, but it's clearly Damian's mind controlling the body, and accents are not genetic. If this was indeed due to Mark's mind remaining in the body, Damian should have immediately noticed something was wrong.

However, Damian wasn't British. Setting aside that there's no such thing as a "British" accent, Sir Ben Kingsley does make an effort in the early part of the film to conceal his natural English accent.

Near the beginning, the make of the black SUV tailing Damian changes from Chevrolet to GMC depending on the camera's point of view. This is very noticeable, as the two makes mainly differ in the front grille area, which is very prominent.

In dozens of car crashes and collisions in the movie, none of the air bags in the cars ever inflate.

The Panarai Laminar Marina watch worn by Edward does not have an alarm option, though it continually gives off an alarm multiple times.

Damian uses his smartphone in his car to call someone, and his phone screen stays on the whole time.

After they run away from the rest house, the girl asks to pull over to a petrol station. In the car, the car handle is missing, but when they pass by the shop written "time clock", in the front glass, the handle is visible.

Scenes set near St. Louis all have obvious landmarks that are actually located in Laplace, Louisiana, where much of the movie was filmed: Troxie's Motel, the levee, and Fatty's Restaurant (across from Anna's school). Hobnobber's, a prominent New Orleans bar/restaurant, can be seen across from Damian's daughter's non-profit, supposedly set in NYC.

When old Damian's consciousness got transferred to the new body, the doctor asks him name to confirm that the consciousness has got transferred correctly. As Mark's body was a dead body, and it starts moving and showing awareness and is able to speak, there is no other way a dead body can do so unless the consciousness has got transferred. So the question about his name was superfluous.

Damian was a billionaire. After he "died", all his wealth should have been inherited by his only daughter Claire, but at the end of the movie when Claire is visited this is forgotten.

Damian's new identity, Eddie, was born September 20, 1980 in Phoenix, Arizona. Anton's phone shows the date is "Saturday, September 20". At the nightclub that evening, when he recites his birth date, no one comments, or even seems to notice, that's it's his birthday.

When Eddie is looking at Damian's obituary, the text is about an NTSB probe into a train crash. Also, the story is listed under the tab UK on the website.

When Damien goes to Martin's house to ask for use of plane they don't believe it's Damien. If they had gotten their own son through the shedding process, they would have believed him right away. Damien wouldn't of had to being the evidence (old deed) out. The wife wouldn't have wanted to call the police either if they wanted to keep their son's existence so secretive.

When at Martins house while searching for Anna, Damian calls out Hannah.

Despite being credited as "Young Damian" in the credits, the name of Ryan Reynolds' character is revealed to be Mark Bitwell.
