According to THR, this latest development on the script front comes as a result of conflicting creative visions between Ezra Miller and The Flash directors John Francis Daley and Jonathan Goldstein. The duo, who were tapped to helm The Flash early last year, want to go in a lighthearted direction with the movie, similar to what’s been done with Aquaman, which has grossed over $1.1 billion worldwide, and Shazam!, which is getting positive early buzz. Miller, on the other hand, wants The Flash to be darker, and he subsequently took the initiative to work on the script with Grant Morrison, whose DC Comics credits include runs on Batman, Justice League of America, Doom Patrol and, especially fitting here, The Flash, not to mention miniseries like All-Star Superman, Final Crisis and The Multiversity.
