Continuity mistake: When Judy is walking past the shops, parked behind her is a pick up truck full of junk. In front of it is a grey Triumph 2000 estate and a white Citroen, but seconds later when Judy is ambushed by Jackie Heron's gang, the triumph and Citroen have gone, and there are milk floats parked in front of and behind the pick up truck.
