Plot hole: When Quinn is in the airplane, trying to get away, they are already above land, with civilization (you can see some buildings). There goes the whole isolated theory.
Continuity mistake: The blanket covers of the baby change colors from white at the arena field to multicoloured at the arena hallways. (01:22:43)
Continuity mistake: At the very end, when Quinn looks at this newborn baby, he has a little bandage around his right thumb. But earlier, when he was plotting his escape, he sliced of the thumbprint from his LEFT thumb.
Other mistake: You can clearly see Mickey's stunt double's face at the fight in the nursery scene. (00:21:09)
Plot hole: When Quinn wants to escape, he takes a scalpel to slice off his thumbprint. A scalpel is a medical instrument, where did he get it?
Factual error: In the last combat scenes you can see Dennis Rodman firing an AT4 while being in the stadium, but if you know your guns, you sure know that there's at least a 15m minimum safety range BACKWARDS, or you'll get fried.
