The candidate of the Armor of Hammer seems to be suitable at least because it was he who had to play Batman in the "League of Justice" George Miller. The project was canceled, but the actor can still try on a superhero costume. Hammer has experience filming in action films, he is young enough to sign a contract for several films forward, and quite popular to attract the audience. However, it is impossible to unconditionally believe Insiders of the REVENGEOFTHEFANS portal, because their information has denied the Wrap edition, whose sources claim that the studio is looking for an actor even younger army, which is 32 years old. It is worth noting, they repeatedly reported reliable information, which was later confirmed.
The director of the film Matt Rivz emphasized in one of the interviews that the new Batman will show itself primarily as a detective, and not an action hero, and his image will be far from the images of Ben Affleck and Christian Bale. Who will eventually play a cult character of comics, it will become clear quite soon, because the shooting process should start this year.
