He will be playing Atom Smasher, who is described as:
A character who can control his molecular structure and is able to manipulate his size and strength.
This interesting because we have seen this character before in an episode of DC’s The Flash. Now the production start date is still unknown, but this will be the centerpiece of DC’s fan event, DC Fandome.
This still isn’t a release date just yet, hopefully, it can eventually start filming within the next year or so.
