I can see Jason vs Michael being the best choice for a live action DB too, so hoping that.
The most bizarre things that happened was in Jason X, which is campy even for a slasher film, so it can be 2-3 minutes and not feel like you need to include more
Both are more down-to-earth and the two are more brutal sluggers compared to Daredevil, Red Hood, Nightwing, and Winter Soldier so it could work with a lower budget and not feel gimped (like how DD vs NW feel it didn't use their acrobatics as well on top of possibly one of THE most underwhelming deaths in the entire franchise or how while RH vs WS worked and used a lot of stunts that felt really good, it felt less like the action flick you'd expect for even street tiers superheroes thats not on the CW).
Settings would be super easy - can film it in someone's house, in-studio, and even in a forest at night, allowing the atmosphere to feel right
