Continuity mistake: On the closeup with Sid sitting on the chair, you see two knitting needles, one on either side of his jacket. When Hatty and Sid are in view, the jacket completely covers the knitting needles, next shot, closeup again, needles seen again. (00:18:40)
Continuity mistake: A suited and booted chap with a flyaway mop of copper hair can be seen walking down the street when Bernie first pulls up outside the Spanners' house. Soon after, the same man can be seen across the road from the parked motorbike. A few seconds later, there he is again, back walking down the street behind Vic.
