Believe it or not, Ezra Miller's cameo as the big-screen incarnation of The Flash in last night's
Crises on Infinite Earths finale was actually Warner Bros.' idea.
Most fans assumed that The CW must have asked the studio if they could bring the
Justice League actor on board to film a scene with Grant Gusten's DC TV take on the Scarlet Speedster, but during an interview with
Variety, Marc Guggenheim revealed that WB boss Peter Roth called him after the crossover event had already wrapped to ask if he could fit Miller in.
"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 on-board with it. And he was. He was incredibly enthusiastic and on-board 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."
Could the studio's desire to get Miller's Flash into the
Crises event have anything to do with the upcoming movie? It was recently confirmed that the first solo outing for the Fastest Man Alive will be a "different" take on
Flashpoint, so there's a good chance some time displacement/reality hopping will factor into the plot.
Whatever the reason, it was a great moment for fans and a genuine surprise. If you missed Miller's scene you can check it out below, along with some behind-the-scenes shots and previously released stills from the
