Character mistake: Near the end of the movie, when Newt and Minho and Frypan and others are all being checked by WCKD's scanners to identify the subjects.

Character mistake: When Gaby's car becomes wedged between two buildings, she says, "Good plan. All we have to do is get over two twenty-foot walls and a minefield." While minimal backstory is given, I think it reasonable to assume that she has lived in what was East Germany all her life. It is thus highly unlikely that she would express a measurement in English units (being bilingual doesn't mean you automatically convert measurements). She would have said something like "six meters."

Character mistake: The poster on the wall near the start reads "Our Egg Donor's [sic.] are helping to fulfill the dreams of women across America." There is an unnecessary apostrophe in the word "Donor's." (00:10:05)
Character mistake: In the exchange at the train station in district 2, Katniss says how she killed Cato in the 74th games, and Cato killed Thresh and Thresh killed Clove etc However Cato didn't kill Thresh - he was attacked by the mutts and killed by them. (00:14:50)
Character mistake: At the truck stop, Mark (young Damian) meets with Martin. Martin tells Mark that he had the shedding pills reverse engineered and hands him a piece of paper. The percentages of the 5 ingredients only add up to 90% rather than 100%. (01:29:25)

Capacity of Goodison Park is 40,000, and even allowing for people in the "pitch" area around the ring there's nowhere near space for that many, unless there was another layer of fans standing on people's shoulders.
