The Great Debate will be a touchstone of nerd culture. Vaughn will be joined by his robot sidekick, DB-8, and celeb panelists who will debate burning questions in science fiction, fantasy, horror, comics and general geekdom.
"Who'd be a worse boss, Darth Vader or the Joker?" and "Would you rather have a Green Lantern ring or a Wizard Wand?" Look out for the answers when The Great Debate premieres June 18 at 11pm EST.
