In a previous report, there were three contenders for the role of Iris West. Finally, Warner Bros. has made a decision. Kiersey Clemons joins "The Flash" cast, and she will portray the role of Barry Allen/The Flash's (Ezra Miller) love interest, Iris West.

The studio was eyeing three actresses, and among them were Clemons, Rita Ora, and Lucy Boynton. "Dope" actress has been the top choice, according to the insider of Variety.

Originally, Seth Grahame-Smith was set to helm "The Flash" movie, however, due to creative differences, he left the productions, and replaced by "Dope" helmer Rick Famuyiwa. Some reports suggest that filming will start this year. The studio keeps Smith's recent draft of the script, which said based on a treatment by Chris Miller and Phil Lord.
