Anachronisms: When Ivan and Carole have a brief talk on the banks of the Danube near the bridge, we see evening traffic on the quay at the opposite side of the river, with a considerable amount of cars passing by, headlights on. There would not have been this amount of traffic in Budapest in the 1950s.
Anachronisms: When fencing for the gold medal, Adam Sors' opponent has his foot way across the line at the start. This would never be allowed at the Olympics.
