Gunn marked the beginning of filming in February 2024 by posting a picture of Superman's shield, which commentators noted for its visual similarity to the character's costume in the Kingdom Come comic book, albeit with the classic yellow and red color scheme. Safran promoted the film on-stage during Warner Bros.' CinemaCon presentation that April, with Gunn, Corenswet, and Brosnahan appearing via video messages. The panel unveiled a full look at the film's Superman emblem and Gunn said he planned to attend the following year's event in-person with the cast to initiate the "Summer of Superman" in the lead-up to the film's release. Gunn released a first-look image of Corenswet in costume in early May, which depicts Superman suiting up while an alien-looking threat attacks in the background. Commentary on the image focused on the return of red briefs which were not included in the ''Man of Steel'' design. Elements of the costume were also compared to the design used in the New 52 comics by Jim Lee, while the character's pose and the attack in the background led to speculation about Superman's characterization in the film and what threats he may face. A display inspired by the film's Fortress of Solitude was included at Warner Bros.' Licensing Expo booth in Las Vegas later in May.
