Ezra Miller, who has played The Flash since Batman v Superman: Dawn of Justice, is now said to be writing a version of the script for The Flash with comics author Grant Morrison.
As reported by THR, this move is in response to a “clash of creative visions” between directors John Francis Daley and Jonathan Goldstein, who want a more light-hearted approach, and Miller who “is said to want a darker take on the material.”
Additionally, these sources say that the script may be ready to submitted to the studio as early as next week.
It is said that if WB decides to go against Miller and Morrison’s take on The Flash, “the actor could part ways with the project,” as “Miller’s holding deal on Flash expires May.”
