A dark and evil take on the classic origin story of the world’s first superhero, Superman, “Brightburn” was met with mixed reactions from crowds. Being considered a good film but lacking in some areas, “Brightburn” still managed to quintuple their budget at the box office, basically ensuring that they will get a sequel (by modern Hollywood standards).
The world of “Brightburn” is said to have a lot more that can be developed within it. Perhaps instead of a world with superheroes, we only end up with a world full of supervillains. With every supervillain being a new take on the classic origin story. Perhaps an evil Aquaman, such as what was hinted in the credits of the first film? Who knows?
Right now James Gunn is busy working on “The Suicide Squad” and “Guardians of the Galaxy 3” so he may not be apart of these discussions for a new sequel. Yet, he may not have to be. The production for the first film was shrouded in secrecy, with no one knowing about it unless you were involved or until the trailer was dropped, so maybe the second is going to be somewhat the same?
