In case anybody wanted to know what that big blue thing was in the sky was during that one shot. It is a part of the story of the All-Star Superman comic, which this movie is going to be partially based.
I am also guessing Lantern and his group of heroes is gonna be kind of a take off of the Kingdom Come comic. The edgy superheros who don't play by the rules and are antithetical to what Superman is about.
My guess is they’re a Justice Society that is kind of corporately owned. Just based on all of their uniforms being essentially the same
"Krypto arrives on screens in 'Superman' this summer. Krypto was inspired by our dog Ozu, who we adopted shortly after I started writing 'Superman.' Ozu, who came from a hoarding situation in a backyard with 60 other dogs & never knew human beings, was problematic to say the least. He immediately came in & destroyed our home, our shoes, our furniture - he even ate my laptop. It took a long time before he would even let us touch him. I remember thinking, 'Gosh, how difficult would life be if Ozu had superpowers?' - and thus Krypto came into the script & changed the shape of the story as Ozu was changing my life. What better time to debut the not-so-good-good-boy Krypto than 'Adopt A Shelter Dog' Month. Btw, Ozu today, is, fairly often, a very good boy." From his og instagram post about it.
