I mean, why can’t Plastic Man be in his 40s? We might get a movie for him someday, but I doubt it becomes a full-blown trilogy or epic saga—nor do I really want that, honestly. Maybe he pops up in a Justice League flick. Or a fun cameo here & there. Better yet, give him an animated series. Then who cares how old he is?
I get the need for strategic casting when it comes to the Trinity, sidekicks, and some
JL’ers— but 3/4 of our current Justice Gang characters are over 40, so I don’t think that needs to be a dealbreaker in the DCU. I wasn’t watching any of those actors in Superman thinking “oh, that’s the old one.”
