The same month, DC published a Free Comic Book Day sneak preview of "Superman Unchained", an ongoing series written by Snyder and illustrated by Jim Lee, which was later published on June 12, 2013, and intended to coincide with the feature film "Man of Steel", which opened two days later. Snyder explained his approach to the series: "The way to approach a character as iconic as him is you just come at it from a standpoint of what you love the most about the character, and then write a story that explores that, tear it down and build it back up."
