If you didn't know - Michael Shannon happens to be a big fan of Aquaman.
Shannon previously said if he could play a superhero, it would be Aquaman.
"You know who I really want to play?" Shannon said. "Aquaman. If they ever make a fucking Aquaman movie, I want to be Aquaman."
Shannon said that over a year ago, and now the actor has been spotted at the Sundance Film Festival wearing an Aquaman t-shirt.
Jason Momoa was recently cast as Aquaman and also attended the Sundance Film Festival where Michael Shannon wearing the Aquaman t-shirt was brought up. Momoa didn't have much to say about it other than "that's awesome."
Michael Shannon played Zod for Zack Snyder in Man of Steel. Various fan theories are speculating that Lex Luthor gets a hold of Zod's body and uses the Kryptonian armor to make the Lex Luthor Warsuit from the comic books.
