Near the start when B and Sophie are driving along the cliff, the aerial shot shows the cliff to be on the left of the road. Then a shot from inside the car shows trees in the background where the cliff was. The when they stop in front of the dead cow, the cliff is on the right side.
When the vehicles go to Dokovo to find Nikolai's house, one overhead shot shows the vehicles driving along with flags flying on the driver's side of each. Every other shot (overhead and ground level) shows the flags on the passenger side, indicating that this overhead shot has been reversed.
