Continuity mistake: After Batman shoots Reverse Flash through the head, Flash rushes over to Batman and catches him before he falls over from his wounds. As Flash is lying him down slowly, there is no blood on Batman's face. It then cuts to a close up as Batman reaches up to pull off his mask and there is suddenly blood on his lips and chin.

Continuity mistake: After catching the rocket and saving Cyborg and Batman from it, Superman turns and drops the exploded rocket and begins lifting into the air. It cuts to a wide angle as Superman is hovering above the ground, and the rocket he just dropped is nowhere to be seen. (00:52:05)
Continuity mistake: After Aquaman finds Orm dead and sees the carnage of the battle, Wonder Woman comes up behind him and stabs his back with her sword. He falls to his knees and she walks around in front of him, and as she does you can see there is no blood on her sword. But then she holds the sword to his neck in a close up and suddenly the sword is covered in Aquaman's blood. (01:10:15)
Trivia: After the ending credits, there is an additional scene showing an alien invasion appear from a temporal rift. This is likely an homage to the upcoming movie, Justice League: War, which is the story of the Justice League first forming in order to combat an alien invasion. (01:20:50)
Deathstroke: That's a lot of death... Even for me.
Barry Allen: War? What? No mom, I'm fine. But everything else has changed, and I have to find out why. I think it probably has something to do with me being-
Nora Allen: Gay?
Barry Allen: What? No.
Nora Allen: It's okay, I love you no mater what.
Question: Barry returns to his fixed timeline, meets Batman and gave him the letter Thomas Wayne's Batman wrote. Then, the post credit scene shows the portals appears that will lead to Darkseid's invasion. The question is in the following Justice League War movie, the heroes seems like they never know each other. Did Barry return before the Justice League ever assembled? If so, why does Barry in the Justice League War movie seem to be so amused when he knows Batman is real? He even greeted Batman for the first time and addressed him as "Sir Batman." I cannot find any good articles on net to explain this contradiction.
Chosen answer: Despite the ending in Flashpoint to indicate a Darkseid invasion, War is not a sequel. It's a reboot. While both films were part of the DC Universe Animated Original Movies series, War is the first movie of the series that is now part of the DC Animated Movie Universe. This is also why the voice actors are different.
Question: What did Cyborg do with Yo-Yo after he catches her? Right after he catches her, he suddenly jumps up on the roof with Batman and talks with very little time in between.
Chosen answer: He probably turned her over to the police. There's no knowing how much time passed between when he caught her and when he jumped on the roof to chat with Batman.
Answer: Flash couldn't travel through time later in the movie not because Zoom was alive but because Zoom was also tapping into the Speed Force, preventing Flash from gathering enough of the Speed Force to break the Time Barrier. When Flash originally went back in time it's likely because Zoom was in custody, therefore not tapping into the Speed Force at that time.
