Warner Bros. has released a behind-the-scenes look at Superman (2025) titled “Filmed for IMAX®,” giving fans their most immersive peek yet at the scale and ambition behind James Gunn’s DC Universe relaunch. Designed to be experienced in full IMAX 1.90:1 aspect ratio, the footage features sweeping set pieces, towering practical builds, and first glimpses of Superman in flight across expansive American landscapes.

Director James Gunn narrates portions of the video, underscoring his commitment to grounding the film’s spectacle in emotion and character. “We didn’t just want the action to be big,” Gunn says, “we wanted it to feel big—to mean something.” The featurette includes production shots of David Corenswet suited up as Superman, Rachel Brosnahan as Lois Lane, and Nicholas Hoult as Lex Luthor, hinting at the dynamic interplay between hero, journalist, and villain that defines the heart of the film.

The IMAX footage emphasizes natural lighting, large-scale sets, and vivid contrast between Clark Kent’s Kansas roots and the grandeur of his Kryptonian heritage. From cornfields to craters, and newsroom interiors to planetary transmissions, every detail feels constructed to immerse audiences in both myth and intimacy.

The clip ends with Gunn and the crew watching playback on towering IMAX monitors, visibly proud of the visual depth they’re delivering. It’s clear Superman is not just a film—it’s an event calibrated for maximum theatrical impact.
