Reeves...moved to the top of the shortlist and entered negotiations after meeting with Warner Bros. on February 10, 2017.
[93] Warner Bros. sent Reeves a copy of the script, but Reeves felt that Affleck's take, while "totally valid", was not the film he wanted to make.
[95] Reeves only wanted to join if he was guaranteed creative control, and Warner Bros. Pictures Group chair
Toby Emmerich—who wanted an "auteur" to make the next
Batman film—was impressed by his initial ideas.
[96] ...Reeves was hired to direct
The Batman on February 23.
[97][98] Reeves was not willing to share his full vision with the studio while he was working on
War for the Planet of the Apes (2017), and Warner Bros. agreed to delay production until he was available.
[95]
Reeves began working on the script in March 2017.
[100] He initially planned to keep
The Batman's connections to the DCEU, and spoke with Affleck during the writing process,
[101] but soon reworked the story to focus on Batman earlier in his vigilante career,
[102] with plans to cast a younger actor to play Batman;
[103] Warner Bros. was planning to replace Affleck by July 2017.
[104]
When Reeves decided to focus on Batman earlier in his vigilante career, he began writing a new script from scratch.
[102][104] Affleck's script had taken an action-driven, "
James Bond-ian" approach, but Reeves wanted a more personal narrative that "rock[ed Batman] to his core".
[95] He wanted to explore how the Batman
mythos could exist in the real world...
Reeves originally intended for his version of
The Batman to be set in the DCEU,
[101][115] but eventually decided that this would distract from Batman's character arc and asked Warner Bros. for the creative freedom to move outside of the shared universe.
[116] Reeves wanted to be able to create a version of Batman with a "personal aspect to it", and felt he should not be obligated to connect it to other aspects of the DCEU.
[117] Warner Bros.' incorporation of the
multiverse in its DC productions allowed Reeves to take the project in his own direction;
[116] as a consequence, the film takes place in a separate world known as "Earth-2".
