Other mistake: In the bedroom scene before Dan Evans leaves his family, there are two petroleum lamps attached to the wall and lit up although there is still daylight. Given their financial distress, they would have never done anything like this. Moreover, the light is not flickering because the film crew used light bulbs.
Other mistake: During the film the narrator states: "He also had a condition that was referred to as "granulated eyelids" and it caused him to blink more than usual as if he found creation slightly more than he could accept." However, this never occurs once in the movie and in fact the opposite happens, Jesse stares into space hardly blinking throughout the entire film.
