How about a batman beyond with Michael Keaton as Bruce Wayne and a young potential actor as Terry mcgenus. Set in the Tim burton universe so batman 1989 and 1992 are cannon. Even referencing the anniversary massacre caused my notorious crime boss jack the joker Napier as that would no doubt still be a talked about incident In Gotham history. I would love to see this happen. Just a one shot not tied to anything else.
Idea for DC one shot movies
Yeah, That could actually work pretty well.
