The Flash script apparently is being worked on as we speak, because with several names on the potential director's list, the story will have to shift and grow to meet the needs of the storyteller who eventually is brought on board. Recently, names like Robert Zemeckis and Matthew Vaughn have been circled as possible directors for The Flash. What if they don't want to tell the Flashpoint story? What if they have other ideas? Yes, you introduced Billy Crudup as Henry Allen, but from the looks of it, he's in prison in Justice League. The Flash movie could leave him there. By the time we get to a Flashpoint story, DC could recast.
