Revealing mistake: In the roof top chase between Bond and Mitchell, it is obvious that both characters are wearing black running shoes, when in the previous scene both wore smart black suit shoes.
Revealing mistake: During the opening car chase the police shoot at the bad guy's car and the back window shatters, we then see a close up from the outside of the back window of the bad guy turning around and then returning fire, shooting out the back window. The back window is not shattered but does have bullet holes in it, this is so we can see the men inside the car returning fire.
Revealing mistake: At the end of the opening car chase Bond approaches the safe house. Just before the gates open white tyre marks are visible from previous takes, the white being chalk from the quarry.
