James Gunn Found His Perfect Superman on Day One, Casting David Corenswet as Clark Kent for Legacy

In the summer of 2023, the search for the new Superman was in full swing, centered around James Gunn’s upcoming film Superman: Legacy. By May, several actors were shortlisted for the lead role, including David Corenswet, Tom Brittney, Andrew Richardson, and Nicholas Hoult, with Corenswet and Hoult emerging as frontrunners. Gunn conducted screen tests in June, matching the selected Clark Kent contenders with prospective Lois Lanes Emma Mackey, Phoebe Dynevor, and Rachel Brosnahan to assess chemistry and performance.

From Screen Tests to the Final Choice: Corenswet Triumphs

During the screen tests, these pairs filmed a compelling scene depicting a heated exchange between the Daily Planet’s Clark Kent and Lois Lane. The three Clark Kent candidates—Corenswet, Hoult, and Brittney—then took the next step by performing in full Superman costume for further evaluation. Shortly after reports narrowed down the contenders, James Gunn revealed that David Corenswet had been selected as the new Man of Steel.

In a revealing profile with GQ titled “Can David Corenswet Save Superman?,” Gunn expressed that Corenswet was his top choice from the outset, despite having auditioned around 400 actors. This immediate conviction lingered throughout the meticulous search.

Gunn’s Unwavering Vision of His Superman

From the very beginning, he was the guy to beat, frankly,

Gunn stated. He also reflected on the casting of Lois Lane, saying,

probably [only] the eighth Lois I saw read,

followed by the question,

You [think], God, is this really right? Can it be this easy?

This transparent surprise highlighted how quickly Gunn connected with Corenswet’s portrayal.

Gunn underscored his commitment to the project’s success by revealing,

I said from the beginning, If I don’t find Superman, I’m not going to do this movie. Because I knew that this was dependent on the guy that’s playing Superman.

Known for directing the Guardians of the Galaxy trilogy and The Suicide Squad, Gunn elaborated on his film’s tone as tonally complex, designed to balance

drama, comedy, and action — although I do think that some of the drama and action probably supersedes the comedy in a lot of ways.

Searching for the Right Blend of Appearance and Depth

This layered portrayal of Superman required an actor not only to embody Clark Kent’s mild-mannered persona, including his bumbling reporting style and signature hypno glasses, but also to convincingly portray the humble farm boy from Smallville, Kansas, and the iconic superhero who wears bright red trunks beloved by children around the world.

Gunn explained the challenge in these casting criteria:

I couldn’t go for someone that didn’t work,

he said.

I couldn’t go for someone that had the look, but didn’t have the chops. I couldn’t go for someone that had the chops but didn’t have the look. I couldn’t go for someone that had the looks and the chops, but couldn’t do the comedic parts, or couldn’t do the more vulnerable aspects.

David Corenswet’s Unique Qualities as Superman

Corenswet’s look has been compared to a mix of previous successful Superman actors such as Christopher Reeve, Tom Welling, and Henry Cavill. Gunn noted the rarity of an actor who truly resembles the comic book version, remarking,

Actually, a lot of people do not look like Superman.

Corenswet’s strong visual alignment made him stand out as someone who could seem to have stepped out of the pages of Action Comics.

Nicholas Hoult, who was cast as Superman’s adversary Lex Luthor in the film, shared his initial impressions of Corenswet:

When I first read the script, I had a slight instinctive feeling that maybe I’m more suited to Lex in terms of what this character is on the page and what I’d been doing acting-wise,

Hoult said.

But when I first met David at the screen test, he’d found a patch of sun in the studio and was relaxing in between readings, almost charging up like Superman does from the sun’s power, and there was something about meeting him in that moment…. I mean, he obviously looks exactly like you imagine Clark Kent and Superman to look.

Hoult praised Corenswet’s charisma and style as otherworldly, explaining,

He’s got this Old Hollywood persona which makes him feel even more relevant and timely to this version of Superman and Clark. It’s his charisma, his idiosyncrasies. He is what he idolizes, that silver screen era of acting and musicals.

The Character James Gunn Envisioned

Gunn designed his Superman to represent

truth, justice, and the human way

in a contemporary world that often views kindness as outdated. Corenswet’s performance in a key 10-page scene where Lois Lane interviews Clark Kent—not the cape-wearing superhero but the man beneath the suit—captured the old-fashioned charm Gunn sought to evoke.

Corenswet reflected on the humor he introduced to the character, saying,

James has told me that the one thing that surprised him, that meant something to him initially, was the humor that I brought to that first scene,

and added,

I immediately read it in the terms of the movies that I grew up on, which are Singin’ in the Rain and His Girl Friday, and the Fred Astaire and Ginger Rogers movies. Just the timing and the patter and the style of humor — and it turned out that that was what he was imagining.
