SUPERMAN Making-Of Documentary Hints at the Super Family vs. Brainiac in a Sequel

DC Studios and Warner Bros. have just released an hour-long documentary on the making of James Gunn’s Superman called Adventures in the Making of Superman, now available on YouTube. It’s a fascinating behind-the-scenes look at the process of relaunching the iconic character. And thanks to Comic Book Movie, we’ve learned that some eagle-eyed viewers noticed something interesting in the doc. There’s a storyboard that may hint at what we could see in the follow-up that Gunn is currently writing. It shows Superman, Supergirl, and Krypto flying together, and in the bottom left corner is the unmistakable head of Brainiac, one of Superman’s greatest foes. Is the new movie indeed a Superman Family movie, where the El family takes on the evil A.I. from space?

Well… that's interesting.

Gunn has said via social media that Brainiac was once considered for Superman. Which makes sense, as the character remains one of the Man of Steel’s most prominent enemies. In fact, we’d say he’s second only to Lex Luthor. And for some reason, we’ve never seen him in any live-action film before. This despite getting Luthor six times now, and General Zod twice. It’s about time the alien android from Colu (or Krypton, in Superman: The Animated Series) gets a big screen debut. The TV series Krypton did a pretty decent version of Brainiac, and they did that on a relatively low-budget series. We’re sure Gunn could do even better.

Brainiac has a long history with Krypton, shrinking its capital city, Kandor, and its inhabitants to keep in a bottle. So it makes sense that this could be an adventure for the whole Superman family together. In the comics, Kara Zor-El has memories of Brainiac coming to Krypton during her childhood, and has a connection to him that her cousin Kal-El does not. And we still contend that this would be the perfect opportunity to bring in Superboy/Conner Kent, and maybe even upgrade Lois Lane to Superwoman. At least for one big cosmic adventure. If Gunn has something even remotely close to this planned, we are very here for it.
