During a SnyderCon Q&A session, Batman v Superman: Dawn of Justice director Zack Snyder revealed some details about a storyline that his Justice League 2 would have continued.
When asked if fans would have seen the other side of The Flash‘s cameo appearance in Batman v Superman: Dawn of Justice at a later point in Snyder’s DC Extended Universe, Snyder responded. “Absolutely.”
The director elaborated on what would have been shown, stating, “The idea was that in whatever Justice League that would have been — Justice League 2, I guess … there was a scene where … Flash was getting ready to go back in time, and the idea was that … Bruce said to him that there were two possible windows in which he could jump back through time.
“And Bruce said, ‘Well, which one would you have gone through if I didn’t say anything?’ And he [Flash] said, ‘We were going to go through this one,’ and he [Batman] said, ‘Don’t go through that one! Because you went through it and it didn’t work … So go through the other one.’ So you would have seen that. Then he would have gone to the correct moment.”
Did the Flash appear in Batman v Superman: Dawn of Justice?
The Flash had a cameo in Batman v Superman: Dawn of Justice, which featured the speedster hero coming back through time in a dream sequence to warn Bruce Wayne that “Lois Lane was the key.” The scene ends with the Flash saying he arrived too early to warn Batman, and that Wayne was right about Superman. According to Snyder, we would have seen this scene from the other side in Justice League 2.
Batman v Superman: Dawn of Justice first released in 2016. Directed by Zack Snyder and written by Chris Terrio and David S. Goyer, the movie would go on to receive a director’s cut release, which had an R rating and a minute longer runtime than the theatrical cut by 31 minutes.
