After Marta has finished her attack and she is returning from the opponent side, the wire is still running behind her.
Nelis was not arrested after the fencing tournament in Leningrad.
Endel Nelis arrived in Haapsalu in 1950, not in 1952, and he started teaching in the 1st High School, not in the 2nd.
Endel Nelis was already married when he arrived in Haapsalu.
Nelis never wore street shoes or boots inside the gym, he was barefoot or wore sporting shoes.
Children who participated in the fencing classes were actually older, the youngest were about 13 or 14 years old, not 5 or 6 as shown in the movie.
When Endel returns from Russia and steps out of the train, there are 2 camera angles showing the train from both ends. Though there is steam coming beneath of the carriage, there is no locomotive seen.
