Continuity mistake: In the final scene when the three squad cars, a Granada, a Triumph and a Cortina, are chasing the villain's Jaguar across the field, the angle changes and the Cortina has disappeared. When the chase changes to a lane the Cortina reappears. (00:46:36 - 00:47:22)
Visible crew/equipment: When the squad cars are chasing the Jaguar across the muddy field you can see the camera vehicle in front of them is spraying up water from the wet grass. (00:46:36 - 00:47:14)
Continuity mistake: During the car chase at the airfield, after the Triumph crashes into the villain's Jaguar, spinning it round, the chase suddenly changes from the airfield to a lane.
