Factual error: At the end of the movie they say that Bill Kraus died on January 26th, 1986 but he actually died on January 11th, 1986.
Continuity mistake: Towards the end of the movie when Don cannot sleep and goes to the cafe where he sees Jim, he enters the cafe and it is dark and raining. A few minutes later during the shots where the camera is on Jim, the window is behind him and you can now see it is very light outside.
Continuity mistake: When Don is in the cafe he is wearing a wedding ring then throughout the movie he is not. (02:00:17)
Other mistake: When the child takes Don and his colleague to see a pile of Ebola fever victims, the camera lingers on the "corpse" of a man who is breathing.
