So a Superman/Batman team-up movie is happening. Director Zack Snyder's announcement at the Warner Bros. panel on Saturday was perhaps the biggest news out of Comic-Con this weekend. And while we know almost nothing about the film, it turns out Man of Steel co-writer David Goyer, who is also penning the sequel, let slip the likely name of the film at a different panel.

Goyer said the following at the Superman 75th Anniversary Panel , but the reveal was drowned out in the craziness of the day's bigger Hall H panels: “We aren’t sure if the title will be Batman Vs Superman or Superman Vs Batman, but they will face off.” (Snyder did say on Saturday that that the iconic The Dark Knight Returns -- wherein the two fight it out -- will "inform" the film.) Slash Film has looked into which website URLs Warner Bros. owns that track with those titles. The site reports that they own both SupermanVsBatman.com and BatmanVsSuperman.com, plus BatmanVsSupermanMovie.com -- but not SupermanVsBatmanMovie.com. So the current best guess is that the film will be called… Batman Vs. Superman.But hey, either title is great. Simple and evocative. And I, for one, can't wait to see Batman kick Superman's ass!
