When Warner Bros. announced their DC Films slate, Justice League Part One and Justice League Part Two were among them. The mixed response to Batman v Superman: Dawn of Justice brought a halt to plans to shoot them back to back but it appears as if Zack Snyder still planned on finishing the upcoming November release with a cliffhanger ending which would have set the stage for the sequel.According to Slash Film , Justice League was supposed to end with Darkseid's arrival on Earth with the plan being for him to be the big bad in the follow-up. This was to be expected as Steppenwolf has always felt like a stepping stone to that iconic villain but that ending has now been totally scrapped.Apparently, Wonder Woman star Robin Wright has been brought in for a flashback shedding more light on Steppenwolf's origin and the looming threat of Darkseid is being downplayed with the reshoots (presumably to keep the door open for a new villain to take centre stage in the sequel or to give Warner Bros. time to reassess where the franchise goes from here if Snyder doesn't make his return).
