Continuity mistake: Peacemaker and Bloodsport are following Amanda Waller through the female section. There are two girls at the table in the center, one with patchwork colorful skin, the other whistling at them. When it cuts to a close-up, neither is in the appropriate position; the whistler's hand dropped and the Kaleidoscope, who already got up, still has her forearms on the table. (00:20:40)
Other mistake: Javelin already appears amongst the deceased (red layer) on the monitors, but only intermittently, in different shots his status is normal - at the very least he should have the 'critical condition' brown overlay that TDK has. (00:14:00)
Continuity mistake: In the suicide mission on the beach, Flag makes a run for it behind Harley who just ducked behind a rock. Harley is in a dark corner; Flag dives by her, and the camera angle changes showing her into the spotlight. Sane later when TDK's arms are floating and pass by them in bright light. (00:09:55)
Continuity mistake: Blackguard is panicking because of 'the werewolf' but Rick Flag interjects that he's 'harmless'. He then has to add that he's not -that - harmless, having slaughtered a couple dozens of kids; when the camera angle changes before he says that, the actors have changed positions. For instance, Margot Robbie had her hands clasped together before her chest, then she has them in her lap. (00:05:45)
Character mistake: David Dastmalchian is the Polka-Dot Man, hyphenated in the comics, and in the end credits of the movie. Then again, when Waller threatens to kill everyone off, the name of the character appears in print as Polka Dot Man, no hyphen. (01:49:40)
Answer: Yes, it did.
