The live action debut of Damian Wayne, Bruce Wayne's biological son.
Alan Ritchson, Jensen Ackles, and Winston Duke expressed interest in taking on the role of Bruce Wayne/Batman for this movie. Ackles was previously considered to play Batman in Batman v Superman: Dawn of Justice (2016), and ended up voicing the character in Batman: The Long Halloween (2021), Legion of Super-Heroes (2023), Justice League: Warworld (2023), and the multi-part adaptation of Crisis on Infinite Earths.
Rumors spread that academy award winning screenwriter John Logan was going to write the film's script. However this was later debunked by James Gunn.
James Gunn stated he has been in numerous talks with Matt Reeves, the director of "The Batman" 2022. And that he will allow Reeves to have full creative freedom of his version of the Batman while a majority of their discussions revolve around not making both of their Batman projects too similar.
