At the beginning of the tournament, Bogart's odds are listed at 9-1 and, after he cuts out his tracking device, Powers tells his assistant to shorten his odds even further. However, during the "Ev'ry Time We Say Goodbye" montage, they are shown as 20-1, before being down to a more logical 4-1 during the climactic chase on the freeway.
During the final highway chase, Joshua's truck appears both with the headlights smashed and on, several times, going back and forth until the truck rolls over and even then, the truck still has the right headlight on.
When Anton tosses his tracker into the coffee pot it is seen to immediately sink to the bottom, however when Father MacAvoy drinks the coffee containing the tracker he only takes one quick drink from the top which would not have been enough for the tracker to enter his mouth.
When Lai Lai opens the suitcase and holds up the 9PM there is a close up of her hand. Then the next shot is of her turning off the shower, with a noticeably very different hand.
When the scene of all the random assassin's dying to the music is taking place, one scene shows the clock at 6:38 and change remaining, but 2 scene flicks later it shows the clock behind the Host, and it's at 7:01 remaining.
A common mistake in cheesy action films is when characters fire endlessly without ever reloading or running out of ammunition. That happens a lot in this film, one example being when Slade uses a pump action shotgun in the stripper club. He fires ten shots in total, but even the biggest pump action shotguns have an absolute capacity of eight+one (eight in the tube magazine and one in the chamber).
When they showed that 6 players left in fact there were 5 - Harlow, McAvoy, Lai Lai Zhen, Bogart and Topuzov.
Miles Slade's face had extended burns after Joshua Harlow split alcohol on him. But no hair from his beard and eyelashes was burned, as clearly visible on his first contact with Father MacAvoy in the car.
(at around 1h 12 mins) When Joshua follow Lai Lai Zhen by a oil container he hits the passenger bus several times which Lai Lai Zhen was in and father MacAvoy was driving. But we cant see any excitement among the passenger though so many shooting took place. Some passengers were sleeping even after Joshua hits the bus several times.
Around 1h14m34s the smoke trail from the pyrotechnic used to flip the vehicle is visible during the motorway chase after the red car is launched into the air following one of the crashes
In the High street scene a shop with the phone number 0161 displayed which is a Manchester phone number. Middlesbrough is 01642 where the film is set. The card that Lai Lai Zhen refers to when she gets off the phone also has a postcode M14... which is also Manchester. Middlesborough would be a TS postcode.
In the closing scenes, areas are shown cordoned off with yellow "police line - do not cross" tape. This is from the US ; English police use blue and white tape, with just the word "police".
At the end of the opening contest an announcement comes on the screen stating 'Middlesborough, Teeside' with a background scene of chemical works then there's a shot of blocks of flats. If the image (if watching on dvd) is frozen the Get Carter car park is recognisable in the background and the blocks of flats, now demolished, were near by. Robert Carlyle is then seen walking along the old High Street in Gateshead and at one point is thrown out of Ye Old Fleece pub.
An early twist is a contestant able to remove the tracker. But qualified surgeons ought to be able to place it somewhere impossible for a single individual with a pen knife.
When Anton is chasing Lai Lai, the second time he pulls out his guns and puts them away, as he's running up another set of stairs and pipes on the side, the gun in his "left" holster actually falls out.
