Revealing mistake: While in the police car, immediately after the driver hangs up the phone, he makes a sharp turn to the left (screen right).

Grant is then forced to push him aside and physically nudge him.

Revealing mistake: When Thornhill's cab arrives at the UN there's a couple behind him, a rear projection. Later on, when Valerian's car arrives at the UN the same projection is used, with the couple a mere two meters away from where they were before.
