Adam's hair is noticeably longer during the scene where he and Jo search Pollard's office than in previous or subsequent scenes.
When Adam meets Harry at the Greyhound racing, in the first shot it shows Harry eating something from a polystyrene cup in his hand, in the next shot however the cup has disappeared. Later on in the scene the cup reappears.
When Louis Khurvin is being handed back over the Americans we see Zaf standing by the helicopter shouting and directing him, however in when the camera angle changes on the same scene, we see Zaf is stood totally still and is silent.
