Although fans are still reeling from "Crisis on Infinite Earths," the Arrowverse's producers aren’t resting on their laurels. Crossover producer Marc Guggenheim explained he is already brainstorming “ideas for ideas” regarding another crossover event, before joking about how he is working with the equivalent to Avengers: Endgame’s catering budget.

“I would say I have ‘ideas for ideas,’ and I’ve sort of pitched to [The CW CEO] Mark Pedowitz and [executive producer] Greg Berlanti what, if left to my own devices, I would like to see us do,” Guggenheim told TVLine. “There is a rubric that is semi in place… and both Mark and Greg have signed off on that, and as we go onward, things will get more and more specific. I was emailing Mark just the other day, that we have to all get in a room together to talk about this. We typically do a post-mortem about what went right, what went wrong, what did we learn…. We always learn something.”

With fans eager to see their favorite superheroes continue to cross over, Guggenheim explained that, come what may, they don’t intend to “go as big” in their follow up efforts. “Look, I hate comparisons to [Avengers:] Endgame, beacuse it’s just not fair -- we’re working with Endgame's catering budget -- but Marvel didn’t follow up Endgame with Endgame 2. I think you’ve got to build to an event of this kind. The one thing we’re all in agreement on -- cast, crew executives, you name it -- is that we’re not going to go as big next year. In fact, Mark [Pedowitz] and I were talking about ‘returning to the roots’ of our crossovers, and I’ll leave it to people to interpret what that means.”

"Crisis on Infinite Earths," the latest five-show crossover between all the Arrowverse series, is now available on The CW's streaming service in its entirety.
