Just hours after the first teaser for James Gunn's Superman landed on December 19, a former Man of Steel waded into the online debate. Actor Dean Cain — who played Clark Kent in the 1990s series Lois & Clark — reposted a photo of Millie Alcock, 26, in her Supergirl costume with ear piercings and added a thinking-face emoji. Within hours, the comments section turned into a battleground over the casting of the upcoming DC film, according to a report on the exchange.

Dean Cain's 'Sushi Man' retort and the fan backlash

When a user urged Cain to show kindness to the young actor, Cain responded with a barbed callback: 'They called me Sushi Man,' referring to racist abuse he faced during his own Superman tenure. The remark, reported by the original article, drew a swift rebuke from the same fan: 'Bang out of order calling you that btw.' The exchange underscores how quickly past wounds resurface in casting debates — and how a single comment can derail a conversation about a new actor's merits.

Another user weighed in, arguing that the studio was releasing intentionally unflattering promotional images of Alcock and predicting the film 'is gonna suck anyway.' Cain insisted he never called Alcock ugly, but the damage to the narrative was done. As the source notes, the debate highlights the challenges of handing a beloved role to a new face in the age of social media.

Millie Alcock at 26: the fan-driven scrutiny over Supergirl's look

The core of the dispute was not Alcock's acting ability but her physical appearance in the leaked set photos — ear piercings and all. Fans compared her to Melissa Benoist's well-liked Supergirl from the CW series, while others defended the casting as a fresh take. According to the article, one supporter wrote: 'Millie Alcock isn't ugly. They just put out terrible pictures of her.' This fixation on appearance, rather than performance, is a familiar pattern in superhero fandom — and one that Gunn's reboot is trying to sidestep by focusing on character rather than comic-book-perfect physiques.

The film, originally titled Superman: Legacy, was announced in January 2023, just a month after Henry Cavill confirmed he would no longer wear the cape. David Corenswet (of Twisters) now steps into the role opposite The Marvelous Mrs. Maisel's Rachel Brosnahan as Lois Lane. The December 19 teaser was the first official look at the new universe.

Why the 'Superman: Legacy' title was dropped — and what it signals

Gunn's decision to rebrand the film from Superman: Legacy to simply Superman was a deliberate move to signal a clean break from the Snyder-era continuity. The report does not elaborate on the reasons, but the shift implies a return to the character's roots rather than a direct sequel or legacy story. That choice now collides with the reality that fans — and former stars — are still deeply attached to what came before. Cain's involvement in the criticism is a reminder that the legacy of previous Supermen will shadow Corenswet's performance long after the credits roll .

The open question, as the source leaves it, is whether the studio will engage with this backlash or let the film speak for itself. Gunn has been active on social media in the past, but has so far stayed silent on this specific exchange.

What the exchange says about social media's grip on casting

The entire debate unfolded in a single Twitter thread — no press release, no studio statement. A former actor's emoji became a news cycle.. As the original article suggests, this highlights how fan loyalty and social media amplify every wrinkle in the casting process. For Gunn,the challenge is to convince a divided audience that this Superman is not just another reboot but a sincere reimagining. For Alcock, the scrutiny is an early test of her resilience in the spotlight.
