But wait, that's not all: The actor is penning the script with superstar comics author Grant Morrison.

In a bid to keep himself involved as the Scarlet Speedster, actor Ezra Miller is taking a hands-on approach to The Flash. Miller is taking a stab at writing the script for the Warner Bros. project, The Hollywood Reporter has learned. He has teamed with Grant Morrison, the acclaimed comics author, to pen a draft that could determine if he stays on as star, playing crimefighter Barry Allen. The development has bubbled up from a clash of creative visions. John Francis Daley and Jonathan Goldstein, who have been on board the project since January 2018, have taken a light-hearted approach to the material (and even hail from that sort of background, with credits like Spider-Man: Homecoming and Game Night). And, as sources note, that is the general track favored by Warners, which scored a billion-dollar hit with Aquaman by going the fun spectacle route and is seeing strong buzz on Shazam!, which is wearing its “superheroics is fun” on its sleeve.

Miller is said to want a darker take on the material. The two sides have been working on compromises since last year, but Miller took the initiative to tackle the story himself. He partnered with Morrison, with Warners hiring the two to script their take. It is a rare move for an actor to be so invested in a superhero project that they switch hats, but Miller sees himself as deeply committed to the character. Despite its namesake, Flash has been anything but in its journey to the silver screen, going through several directors and writers. Miller, however, has been a constant, having been first cast by filmmaker Zack Snyder for the role in 2016’s Batman v Superman: Dawn of Justice and embracing the role fully in Justice League.
