Continuity mistake: Near the end of the movie, when the helicopter sets down on top of a tall building, the registration mark of the aircraft changes noticeably several times, from G-ORMA to G-ICSG and back again.
Continuity mistake: At the start of the movie, Ian Rider is killed by two bullets shot through his side window. The glass then shatters and forms the word, 'Stormbreaker'. However, when Alex spots his uncle's car in the breaker's yard, there are bullet holes all in the door. They were put in so Alex knew his uncle didn't just die in a car crash, but still.
Continuity mistake: During the scene after 'Training', Alex is at HQ being told he will take the place of Kevin the 'computer nerd'. When Mrs Smith first hands Alex the Computer books in the wide shot, they are being held so that Alex can read the titles. In the close up shot of them landing in his hands, they are parallel to his body. Then, in the next shot, they are back to being the 'right way up'.
Continuity mistake: When Alex walks down the side of the building on his yo-yo, he stops above a window as someone draws the curtains. Then the guards walk past and he is instanly below the window instead of above it. There is not enough time off-screen for him to have walked past it.
Continuity mistake: When Alex climbs out of the chimney in the house at the training camp, there are bits of straw on his woolly hat. In the next shot, they are all gone.
Continuity mistake: When Alex is tied to the chair and Sayle explains about his virus, Alex says "You're not being serious". The shot cuts to Sayle, who is putting a cigar in his mouth. In the shot immediately after it is a close up of Sayle and the cigar is gone.
Continuity mistake: In the scene after Alex is captured, Darrius is doing a monologue with Mr. Grin and Nadia watching and Mr Grin throws a knife into the chair Alex is sitting on, impaling it above his head. All throughout the scene, the space between the knife and Alex's head changes between shots (and, no, it's not just Alex shifting in his seat), and after Darrius says, "Actually, it was a near miss," the camera cuts to a wide shot of the group and the knife is gone altogether.
Continuity mistake: During the conversation at the helipad at the end of the movie, Alex's hair changes between shots, and more than the wind could do.
