Flashpoint: 10 Major New Details You Need To Know About The Flash Movie
7. Jeffrey Dean Morgan's Batman Hopes May Have Gone Out The Window

In June, it was reported that The Walking Dead star Jeffrey Dean Morgan was in early talks with Warner Bros. to join the cast of The Flash as the Thomas Wayne version of Batman. In the Flashpoint Universe Barry Allen creates when he races back in time to save his mother, it was Bruce Wayne who was gunned down in Crime Alley, and Thomas and Martha who survived.
While the latter would later become a twisted version of The Joker, Thomas became the new Batman, and realising that there's a world where his son lives inspires the Dark Knight to help the Flash restore things to the way they should be.
Morgan made a brief appearance as Thomas in Batman v Superman: Dawn of Justice, so this would have been very cool to see. Unfortunately, if any talks were ever taking place, they're not any more based on comments Morgan made during Comic-Con@Home. "Ever since Zack Snyder walked away, my whole kind of bit in that world has walked away with him. However, there’s always a chat going on."
Whatever that "chat" may be, it seems doubtful that it's anything serious based on this next entry...
