Goofs

When Steven comes around the truck to remove the gas pump hose, there is no hose going to the truck. They are all still in their holders on the pump.

When Steve is in a brutal fight with Burke at Burke's home, Steve crawls toward the fireplace and grabs a brass ash shovel and smacks Burke in the knee and head. But when he starts stabbing him with it, it becomes a black iron fireplace poker.

After Arthur's first hit in the movie, the (now deceased) victim is seen floating in the water, then suddenly, with help from Bishop, swimming forward. The camera pans underneath, showing Bishop's hands around the wrists of the corpse, but when seen from above, nothing is, as probably intended, visible.

When being chased on the roof, Steve McKenna shoots someone next to a gray door. He fires two shots but there are three bullet holes in the door.

After the first hit, when Arthur jumps from the bridge from the above angle it looks like he is going to land on a barge, and in the next shot from angle below he falls a few meters in front of the barge - apparently two different shots.

Epinephrine and Adrenaline are the same thing. In the movie they are portrayed as 2 different compounds.

Ketamine does not counteract Adrenaline

During Harry's escape from his office, he sticks scissors into the outlet to kill power to the floor. In reality all this would do is trip the circuit breaker the outlet is wired to, not the entire floor.

The doctor gives the character Vaughn an IV of 1000cc of 0.9% ketamine, or what will be a total of 9,000 mg of ketamine - enough to produce fairly deep general anesthesia in approximately 18 horses.

At shooting practice the slow motion brass shell casing that rotates towards the camera is a blank cartridge not a live round.

During the weapons training montage, slow motion footage of the final round shot from the .50 Cal ejects a bullet casing with a crimped end, clearly revealing it to be a blank.

The scope mounted on Jason Stathams' FN F2000 is mounted backwards

Towards the end of the movie, when Steve pulls out a record to play on Arthur's record player, the cover has "Jazz" written in the corner, however when the music starts, it is Schubert's Trio n#2, which is classical music.

After the first hit, when Arthur jumps into the river and grabs onto the barge to escape, he is clearly moving at the same speed as the barge before he even grabs it.

In the music credit for Schubert's Trio in E-flat (Andante con moto), 'Schubert' is misspelled as 'Scubert'.

When they are hiding in the wall after killing the televangelist, the one security guard hears the ¼" brass nut hit the carpet.

In the basement parking lot the chrome 45 handgun turns into a black one.

At approx 17:45, Arthur is reading an article from the Cape Town Herald about the foiled assassination attempt. In the last sentence of the article, the first part of the statement says that "All five insurgents were stipped of any form of identification..." It should have said "stripped," not "stipped."

During the Cult Leader Assassination Job, the scene is supposed to be set in Chicago. There are shots of the Chicago skyline but the hotel where the action is set was in fact shot in New Orleans. Quick shots of palm trees, external building details and skyline (when the characters are fighting on the rooftop) gives the illusion away.

Although Arthur is supposed to be meticulous, he leaves a highly incriminating gun in a place where it can be found by someone who isn't even making a search.

Hotel room of the Cult Leader is equipped by design with two way mirrors. It may be quite unusual even in Chicago. :-)

While Bishop is exchanging money with the gun dealer when McKenna tags along on a hit, mike is clearly visible for several seconds in the top center frame.

When Arthur is on the phone with Dean and announcing he is coming for him, a boom mic is visible throughout much of the scene, directly above Dean's head.

After Steve McKenna's first kill Arthur Bishop tells him 'I told you to make it clean'; the mic and boom are clearly visible behind Arthur's head extending from round the corner.

Mic is visible when Arthur calls Dave from the conference room in the building.

After the scene when Arthur is leaving money on the table for the girl he slept with in the bar, a boom mic is visible above him.

After Arthur strangles the arms dealer and he sets the laptop to play an erotic clip, he touches the computer with his hands not wearing gloves, leaving his fingerprints on it, which would implicate him. They also both touch the door while leaving.
