When Zack Snyder's Man of Steel comes out next year, it will represent the second time that Warner Bros. has tried to bring back the most famous comic book character in history. When Bryan Singer directed Superman Returns in 2006 it was meant to spring new life into the franchise that had died when Superman IV: The Quest For Peace came out in 1987. Unfortunately the film was rejected by fans and the studio decided to start again with a new origin story. But what if Snyder's version fails? They can just start again, right? Apparently it's not that simple.
