CW President Mark Pedowitz explained that revealing the crossover early was helpful, and it will be “the biggest” and “most complicated” crossover the Arrow-verse has ever done before.
All of this said, there are still a lot of pieces that need to fall into place before we can say for sure what’s leading up to “Crisis on Infinite Earths.”
The teaser that confirmed it’s happening didn’t give much away other than that Psycho Pirate has a part to play, Batwoman will contribute, and “nothing will ever be the same.”
