While director Andy Muschietti teased Keaton’s Batman costume with his own photo on social media, a new fan photo shows Keaton back as Bruce Wayne, reprising his role from 1989’s Batman movie and its sequel, Batman Returns.
“This movie is a bit of a hinge in the sense that it presents a story that implies a unified universe where all the cinematic iterations that we’ve seen before are valid.
I don’t know why, but I am, and so, yeah, I mean, you know, to tell you the truth, somewhere on my iPad is an iteration of the whole Flash thing that I haven’t had time yet… I called them and said, I have to be honest with you.
The Flash movie also stars Sasha Calle as Supergirl, Kiersey Clemons as Iris West, Maribel Verdú as Nora Allen, and Ron Livingston as Henry Allen.
