The highly anticipated moment is nearly here as Superman prepares to launch into theaters next month. With excitement building, director James Gunn and actor David Corenswet have addressed a long-standing mystery in comic book lore: why does Superman wear his underwear outside his suit? This curious question has intrigued fans for decades, and now we have insights directly from the creators.
Why Does Superman Wear His Underwear Outside?

Since Superman’s first appearance in comic books, he has been sporting those signature red trunks on the outside of his suit. But have you ever wondered why? During a recent interview with Fandango, director James Gunn shared his initial thoughts. He revealed that he preferred a modern version without trunks, especially after discussions with Zack Snyder.
However, it was Corenswet who persuaded Gunn to retain the classic look. Gunn admitted that he found the trunks to be somewhat silly, to which Corenswet responded, “Maybe they’re supposed to look a little silly.” His argument was compelling; since Superman is an alien with immense powers, the trunks serve to make him appear more approachable, especially to children. Here’s a glimpse of their conversation:
“David Corenswet: My thing was, maybe they’re supposed to look a little silly. Maybe the reason he wears them is to look a little silly. Basically to undermine how powerful he really is.
James Gunn: In this version of the DCU, everyone knows he’s an alien. He shoots beams out of his eyes, he can blow things down with his breath, he’s sort of this terrifying creature. And David saying that was like… But he really likes kids, and human beings, and people. He wants kids not to be afraid of him. And so that was the thing that made me decide to keep the trunks.”
This perspective is not just charming; it highlights the cast’s deep commitment to representing Superman authentically. They’re not approaching this as just another superhero movie; they are respecting the legacy and meaning behind Superman’s character.
As we eagerly await July 11, 2025, the big screen will once again be graced with Superman’s iconic presence. Will you be there? I certainly hope to see you in the audience!
