Filming
Filming took place in New York City, which was chosen due to being an inspiration for Gotham City in the comics. The film's visual style was primaroy inspired by the Marvel Television Netflix series Luke Cage.

The film made primary use of practical effects. Pace said she took this approach because she felt visual effects "only made things look real", whereas practical effects "allowed things to look and feel real. Because, in a way, they are. They are physically there, so you believe it everytime you see these things onscreen". For scenes featuring both Batman and The Batman Who Laughs, stunt double Vincent Bouillon served as body double was used so that Reeves could have someone to interact with; Pace wanted Bouillon to serbe as Reeves' body double in the role dye to previously serving as his stunt double in John Wick: Chapter 4 and, thus, was familiar with his acting. She wanted the final fight between both Batmans to be "gritty, brutal, and real", something she could be bedt achived if it was filmed between a stunt artist and Reeves, who is known for doing modt if his stunts. She drew inspiration on the climax of Spider-Man for the sequence.
