Visible crew/equipment: As Brannigan sits the drunk man he is questioning down you can see a man with a mustache and glasses in the reflection in the glass as the shot goes to the outside looking in on Brannigan's sweater.
Continuity mistake: During the car chase the jaguar goes over Tower Bridge. Look at the landing - there is no skip or roadworks to be seen, but when the Capri comes over it ends up in a skip surrounded by roadworks.
Continuity mistake: When the cars go over Tower Bridge there is a skip and road works on the take off side but not on the landing side, but the Capri ends up in the skip revealing that the jaguar jump and the Capri jump were done on opposite sides of the bridge.
Factual error: The route to Tower Bridge is completely wrong - there are no duel carriageways approaching the bridge from the Tower of London side of the Thames, it's all single roads in that area.
Continuity mistake: The line of traffic on the landing side of Tower Bridge is completely different to when the jaguar lands and the capri lands.
