Revealing mistake: In the first 'LONDON' scene Turkish discovers Tommy has a gun. Turkish has a bottle of milk in his right hand and when they're talking about the gun, Turkish reaches for it. If you watch carefully here, he subtly passes the bottle off screen to someone so he can use both hands when handling the gun.
Suggested correction: He can just be seen moving the milk bottle off screen to the lower right, but it's not clear that he's "passing it off." He could be placing it on an unseen surface. Not enough information about the layout of the location is available to make a definite statement about what happens to the bottle.
Continuity mistake: When Bullet Tooth Tony is shooting at Boris in the hallway, notice the second shot he takes - no muzzle flash. All of the other shots have one.
Suggested correction: Muzzle flashes have such a short duration; they're often lost between frames in a motion picture. As you know, the camera shutter closes between frames while the film stock is pulled down.
Factual error: At the end of the film when Turkish and Tommy are at the spot where the caravan site use to stand, some police officers come and ask them what they are doing. When the police officer shows his badge which is held in a leather wallet, the badge he shows is one of the royal crest and in London a police officer carries a badge with portcullis symbol on.
Suggested correction: They might have been the Metropolitan Police, whose badge features a royal crown.
Continuity mistake: When Brick top first visits Sol and Vinny, Brick top's henchmen are lining the outer office with plastic sheeting, and laying out their fat accomplice, yet nobody inside hears this.
Suggested correction: They are listening to Bricktop and there is a smaller room in between with both doors shut.
Other mistake: Why does Boris remove and carefully wrap Franky's arm after he's cut it off? It would have been easier to cut at the wrist, therefore removing the need to take a bloody and very odd shaped parcel with you.
Suggested correction: It's a pretty good point you bring up, and as many times as I've seen the movie, I never thought of that. And apparently, neither did Boris. This was a character decision, and one that falls right in line with his flair for the dramatic. We later see him casually walk out of his house with a huge gun and proceeded to walk down the street. I'm sure an arm attached to a briefcase was of no concern to him.
Suggested correction: A character choosing to do something in an arguably non-ideal way isn't a mistake; it's just a decision.
Plot hole: The final boxing match when Mickey is supposed to go down in the 4th is wrong. In the 3rd round, when Mickey is down, Turkish says that all he has to do is stay down. That would be just as bad as Mickey knocking him out.
Suggested correction: Because of the style of the film, as the fight progresses, it gets increasingly unclear when each round ends and starts. The filmmakers simply blended the 3rd and 4th rounds together to add to the blurring of the passing of time. It's similar to how they don't specify or mark the ending of one day and the start of the next, but we know the film doesn't all take place during the same day.
