Factual error: Evita Peron died in 1952. In this movie, the doctor finishes embalming her during the Coup d'état that deposes her husband...in 1955.
Continuity mistake: Charlie's mock trial: the latina maid walks up the stairs, with Sebastian saying "OhmahGod, thank you." In the foreground, London is holding her goblet with her right hand, but in the next shot she has it in her left. (00:05:15)
Character mistake: The protagonist is reading the review of his book "Bitter Tulips." The influential literary critic publication apparently has zero proofreading, since the article says that the novel "can be described as AN failed experiment." (00:45:00)
Continuity mistake: When Nicolas Cage is standing on a roof top patio with the oil industry financier, an orange disappears. The oil guy is peeling an orange as he talks to NC and then when Cage leaves the scene the orange is gone without it ever being eaten or discarded. (01:00:00 - 01:05:00)
Other mistake: When Tilly confronts the teacher Buelah in the classroom, thr letter R is missing from the alphabet across the top of the chalkboard. (01:10:00)
Continuity mistake: Spoiler alert: About halfway through the movie, we see Emma Roberts coming out of the shower, and the camera focuses on the gunshot wound on her shoulder, with the round scar of the entry wound on her back, and the much rougher, ragged scar of the exit wound on her front. Then at the end of the movie, where it's revealed that Kiernan Shipka and Emma Roberts were actually playing the same character, just nine years apart, Kiernan Shipka gets shot by the police officer when he finds her in the room with the severed heads. Problem is: she was facing the officer. The scars on Emma Roberts are the wrong way around. (00:31:05 - 01:15:35)
Revealing mistake: In one of the opening scenes the platoon of the captain is gunned down by a MG42. You can see the crimped fronts of the blanks in the belt.
Continuity mistake: The drawing of the church Kelly shows is different than the one she started to draw, even if she erased lines. The whole thing is shifted over to the right and both top lines go from angling towards the horizon to one being straight.
Factual error: The movie is set in the late 90s but in the parking lot scenes, the pair are surrounded by cars as new as 2012.
Continuity mistake: When the young boy loads his bow and arrow while talking to his older brother, he does this twice without firing it. (00:53:55)
