This week saw the conclusion of The CW’s ambitious Crisis on Infinite Earths crossover, with the DC Comics event saving perhaps its biggest cameo for last as Ezra Miller’s Barry Allen made the jump from the DC Extended Universe to the Arrowverse for a scene alongside Grant Gustin’s Flash – and it seems that Miller’s cameo came at the behest of Warner Bros.
“We were series wrapped on Arrow, and we were wrapped on the whole crossover,” executive producer Marc Guggenheim tells Variety. “We were in post and some episodes were locked, and some were soft-locked. I got a phone call from [Warner Bros. boss] Peter Roth saying, ‘I know you’re locked, but can you put Ezra into the crossover?’ And I said, ‘Yes.’ And he said, ‘How, you’re series wrapped? And you’re wrapped on the crossover.’ And I said, ‘Yeah, I know, but if you’re telling me Ezra Miller can be in the crossover, I can make it happen.’”
“I called Eric Wallace who who is the showrunner of Flash, and he called up Grant Gustin — because the one thing that was our only concern was the thought we didn’t want to do it unless Grant was 100 percent onboard with it,” Guggenheim continues. “And he was. He was incredibly enthusiastic and onboard with it. And then we got on the phone with Ezra Miller and told him the scene I had written and he was completely into it. And we just went. We put together a unit of the Flash crew on the Flash set [since Arrow’s team, which had produced the rest of the hour, was gone]. And much to our surprise, no one noticed Ezra Miller was in Vancouver and no one leaked it from the crew, which we appreciate. So we were able to keep it a surprise.”

Miller last portrayed The Flash in 2017’s Justice League, and it seems he’s finally set to reprise the role for his long-gestating solo movie, with It helmer Andy Muschietti taking on directing duties and a release date of July 2022 now pencilled in.
