The shock cameo in Arrowverse’s Crisis on Infinite Earths that brought the two Flash’s together was actually Warner Bros’ idea.


According to producer Marc Guggenheim, the studio asked to include Ezra Miller’s Flash in the first-ever crossover between the DC Extended Universe and the DCTV shows.

We were series wrapped on Arrow, and we were wrapped on the whole crossover. We were in post and some episodes were locked, and some were soft-locked. I got a phone call from Peter Roth Saying, ‘I know you’re locked but can you put Ezra in the crossover?’ and I said ‘Yes’

The CW’s December crossovers seem to get bigger and bigger. Last year we were introduced to Ruby Rose’s Batwoman, however, this year, DC and The CW pulled off easily the most shocking cameo ever.


While Oliver and Barry were in the speed force, Barry quickly ran to star-labs in search of good memories, however, the only good memory Barry found was the excitement of DC fans.

Standing in confusion was Ezra Miller’s Flash who was introduced in 2016’s Batman V Superman: Dawn Of Justice. Fans of the DC Extended Universe were in shock, especially fans of Zack Snyder’s work, as many asked the same question – how did the CW manage to pull this off?

I called Eric Wallace 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

Warner Brothers. reportedly stated that they don’t want movies and tv shows together on the same screen, which makes sense from a business perspective. However, it was actually Warner Brothers. who came up with the idea to give Miller a cameo.


They even went as far as to say that they wouldn’t add Miller in the series unless Grant Gustin who portrays The Flash on the small screen wasn’t one-hundred-percent on board.

DC fans are already storming the internet with hundreds of theories on why this happened and the most popular theory is that Warner Brothers. is indeed making a Flashpoint film and they introduced Miller to the multiverse so that he can erase other DC stars such as Ben Affleck and create a new timeline for Robert Pattinson.


Crisis On Infinite Earths, the latest DC-Crossover, is available to stream on the CW’s streaming service in its entirety.
