Continuity mistake: In the scene where Jakob discovers Mischa sabotaging the cattle cars and tells him the first news from the radio, Mischa is struck by a guard and knocked off the train, rolling to the ground. He is then bare-headed, but when Jakob runs up to him, Mischa's cap appears on his head.
Revealing mistake: In the beginning of the movie, when Jakob is chasing the newspaper, there are several times you can see the string they use to drag it.
Factual error: In the very last scene the train is stopped by the Russian army and their tanks. The tanks are T-54's, which were not produced until 1955. (01:53:28)
Other mistake: In the scene of Jakob's execution, there is a crowd of prisoners watching (extras). If you look carefully, you can notice a boy that is laughing.
