An important episode in the story of Walraven van Hall is his narrow escape at the barbershop, one of his many escapes. He had a meeting with a resistance fighter in the house located above the barbershop. On his way up, Van Hall was stopped by the hairdresser. The hairdresser forced him to have a shave. While he was sitting in the barber's chair, the Germans arrested the other resistance fighter. Van Hall escaped. This scene can be seen in the film, but with a huge shooting, in which a resistance fighter is murdered in cold blood in the street. In reality this never happened.
in the film Van den Bosch is shot with a number of other people. All are wearing concentration camp suits, complete with the red triangle that political prisoners wore at the time. Such clothing was only worn in concentration camps. In the Netherlands, 'terrorists' were shot dead in their own clothing.
The film contains a meeting raided by the Germans. It culminates in a huge shootout in which at least two resistance fighters are shot. These deaths never happened and furthermore the filmmakers confuse two stories: the betrayal of the later 1940-1945 Foundation and the subsequent betrayal of the National Support Fund. In reality a lawyer named Johan van Lom betrayed the resistance fighters.
It wasn't Walraven but Gijs who invented the switch trick with the promissory notes.
In the film, the co-initiator of the National Support Fund is called 'Van den Berg'; in reality it was Iman J. van den Bosch.
There's a NS 2200 diesel locomotive used in this film which takes place during WW2, the NS 2200 is being operative since 1955, ten years after the war.
