The influence of Superman’s earlier comic book stories is made most obvious by the presence of Krypto the Superdog in the new trailer. However, other elements nod to Superman’s Golden Age stories, which are obscure enough to go largely unnoticed by fans. Looking to some of Superman’s earliest comic book adventures for inspiration is an excellent move on Gunn’s part, showing the writer/director is getting back to the character’s roots for this new movie, which has the daunting task of launching an entire cinematic universe. One particular blink-and-you’ll-miss-it moment in the new trailer recalls one of Superman’s very earliest stories from 1939, which could be a perfect point of reference for the DCU’s Superman.

David Corenswet’s Superman is Flying Back to Boravia

Boravia was last seen in a Blackhawk comic from 1958, but originally appeared in Superman #2 in 1939.
Superman #2 featured the Man of Steel in three separate stories — “The Redemption of Larry Trent,” “Superman Champions Universal Peace!” and “Superman and the Skyscrapers.” The second of these, “Superman Champions Universal Peace!,” saw Superman traveling to Boravia, which was a country locked in a bitter civil war. An arms dealer here had stolen the formula for a powerful poison gas created by an American scientist, which could even penetrate gas masks. Superman flew to Boravia to stop the formula from falling into the wrong hands.
While pursuing the arms dealer who had gotten a hold of the gas formula, Superman became embroiled in the civil war in Boravia. Soldiers from one side of the conflict captured the Man of Steel and attempted to kill him, only to find their weapons were useless against him. Upon escaping, Superman then destroyed the weapons being used by the country’s combatants. After recovering the formula and stopping the arms dealer, Superman took it upon himself to bring peace and ensure Boravia’s civil war was brought to an end. He interrupted a failing peace conference and threatened to bring down the building on the representatives from both sides of the conflict if a peaceful resolution was not reached — they soon overcame their differences.

This Early Superman Story Explores Superman’s Role in the Conflicts of Earth








Importantly, while this story showed Superman taking a stand against war, it also showed him pushing for those directly involved to decide their own terms for peace.
The trailer for Superman includes one sequence in which an angry crowd appears to be protesting Superman, with one onlooker even throwing a can at him. Although the context for this scene is yet to be revealed, clearly the people of Earth have some strong feelings where Superman is concerned. While there are those who see him as a hero, some presumably don’t want an alien meddling in their affairs. Superman will evidently explore the Man of Steel’s struggle to find his place and his role on Earth. There is plenty of discussion of this topic in the comics for the film to draw upon, stretching all the way back to the earliest days of Superman’s life in print, as “Superman Champions Universal Peace!” clearly demonstrates.
