Way back when Justice League was announced, we got a lot of castings and rumors on who would appear in the movie. Then the re-script happened and things changed.
In one of the deleted scenes, we got to see Barry Allen save a woman from a crash. This woman was none other than Iris West played by Kiersey Clemons.
Kiersey Clemons signed on to appear in Justice League but was ultimately cut from the final product.
However, as recent reports suggest that Clemons hasn’t signed back on to appear in “The Flash” standalone movie. A casting call suggests the studio is looking for 21-25 years old to star opposite Miller.
As of now, Ezra Miller is the only one signed on to return to the Flash movie as Clemons and Billy Crudup have both not signed on yet.
It doesn’t mean this is official, the actress could easily sign on closer to production as the production has been delayed with the on-going pandemic.
