Factual error: There is a point when the boy and girl are travelling to Canary Wharf. A couple of shots before they arrive there, you see the DLR train approach a bend (There is a white building to the left). This is approaching "South Quay Plaza" station. This station is two stations past Canary Wharf.Brian Holmes
Factual error: The route the children take to their house on the moped doesn't make sense - this is just to show the London landmarks.
