Is no one else excited about the prospect of this?
I'm surprised nobody else made a thread on this. If true, this is a huge deal. Michael Keaton's Batman helped shape superhero films. He is my 2nd favourite live action Batman, but the idea of him coming back to this universe is more exciting to me than the idea of Ben Affleck continuing the role.
Keaton is one of the greatest actors of all time (See his outstanding performances in: Birdman, Beetlejuice, My Life, The Founder), having excellent performances across pretty much any genre.
I know it's not a sure thing yet, but the idea is so freaking cool.
