The reason WB hasn’t been advertising Superman in the new “Justice League” movie even though Henry Cavill is still casted as Superman in the film is ’cause Superman is dead. At least he’s faking it.
Remember in “Batman v. Superman: Dawn of Justice”, Superman was killed by Doomsday at the end of it. At the end of the film, we see dirt rising off the casket giving us a hint that Superman is actually alive still.
At the end of “Dawn of Justice”, Bruce Wayne says to Wonder Woman, “We have to stand together”. Meaning they are about to form the new Justice League ’cause Bruce Wayne/Batman can’t save the world by himself without Superman, ya know? That’s why he’s forming Justice League.
My prediction in “Justice League” is that we won’t see Superman for most of the entire movie. We won’t see Superman ’til the very end of the film. When the Justice League group are in trouble toward the end of the film, that’s when Superman will finally appear and save the day.
With that being said, though, “Justice League” looks fuckin’ badass and I’m gonna go see it for sure. Can’t wait!
