Plexico had a few ideas for the next big superhero on the screen, even if "Justice League of America" doesn't pan out.
"I think the Flash (from DC) has the potential to be a big hit, given his rogues' gallery and great years of history to work with," he said.
"For Marvel, Moon Knight could be their 'Dark Knight,' at least to a degree. And it would be great to see their 'cosmic' characters break loose on film -- Captain Marvel, Nova, Ms. Marvel and so on."
No matter what Hollywood comes up with next -- there are still rumors of an "Ant Man" film out there and a reboot of "Fantastic Four" -- fans know that after this summer the movie studios will keep trying to assemble the right elements for a superhero blockbuster.
