10. It’s only one film
First things first: there will only be one Justice League movie. Contrary to earlier reports and popular belief, DC are not doing the same as Marvel’s Avengers: Infinity War and splitting their big team-up event into two. Allegedly, this has always been the aim and statements that suggested otherwise were just false.
“We’re only ever planning and we are only doing Justice League, just Justice League,” said producer Deborah Snyder. “One movie.”
According to director Zack Snyder, there will hopefully be a Justice League 2, but it will be more of a separate sequel than a proper part two. That’s probably a good move, considering BvS suffered from having to set up another movie. It will be nice if JL is allowed to stand on its own two (or rather 6×2) feet.
