We're now exactly one year away from the release of Justice League (here's hoping Zack Snyder unveils something to mark the occasion a little later today), and while much of the movie remains a mystery, we do know that it will take us to Atlantis. While there, we'll meet both Mera and Vulko, with the latter set to be played by Willem Dafoe, an actor who is no stranger to the world of comic book movies.Talking to The Guardian , Dafoe confirmed that he'll return as the character in Aquaman and shed some light on how his role in that movie will differ to what sounds like a small cameo in Justice League.he told the site recently.Vulko is an interesting character who, in the comic books, has been both a friend and foe to the King of Atlantis. How his role on the big screen will differ remains to be seen for now, but we'll find out more when Justice League reaches theaters on November 17th, next year. What do you guys think?
