DC Comics traces its own history, from the 1938 debut of Superman in Action Comics through the creation of Batman, Wonder Woman, and the sprawling universe that followed. Writers, artists, and editors including Paul Levitz, Jim Lee, and Neal Adams sit for interviews alongside archival art, early comic pages, and covers spanning eight decades, walking through the company's founding as National Allied Publications, the wartime boom in superhero titles, the industry-rattling Comics Code of the 1950s, and the character reinventions that kept Batman and Superman relevant across changing decades. The film gives real attention to the business side, including the creators who lost rights to characters they invented and the legal fights that followed, alongside the creative choices that turned costumed characters into a shared mythology. Silver Age revivals, the rise of Vertigo's more adult titles, and the push into film and television round out the account. It plays as both a fan history and a plain record of how a small pulp publisher became a mass entertainment company.
