Box office numbers for “Supergirl” look bleak after lead star Milly Alcock sparked backlash for mocking Christian dads.

According to Box Office Theory, the DC superhero movie — which comes out June 26 — is expected to make between $47 million and $65 million in its opening weekend and between $107 million and $181 million in its full domestic run.

The budget for the James Gunn-directed film was reportedly around $170 million, while the marketing spend is estimated to exceed $75 million, bringing the total to around $245 million.

To break even, “Supergirl” needs to make around $425 million worldwide, far less than Box Office Theory’s $350 million global estimation.

By comparison, Gunn’s “Superman” starring David Corenswet opened to $125 domestically in July 2025 and ended its theatrical run with $618 million worldwide. It cost around $325 million to make and promote.

The predicted “Supergirl” box office crisis isn’t helped by the stiff competition the film is facing.

Disney’s “Toy Story 5” comes out one week earlier, on June 19, and is expected to have a $130 million to $160 million domestic opening and $465 million to $600 million domestic total.

Then, just five days after “Supergirl” releases, “Minions & Monsters” will arrive in theaters with an expected opening weekend in the $100 million to $125 million range domestically.

Additionally, the live-action “Moana” comes out July 10, with experts predicting a huge $100 million to $200 million domestic opening.

“Supergirl” stars Alcock, 26, as Clark Kent’s super-powered cousin.

The supporting cast includes Corenswet, Jason Momoa, Matthias Schoenaerts, Eve Ridley, David Krumholtz and Emily Beecham.

During a recent interview with Variety, Alcock pushed back against online critics and suggested the hateful comments come from faceless social media users, including conservative men.

“It’s from a lot of people whose profiles have no photo, who are burner accounts,” Alcock said. “Or someone’s name and then ‘Dad of four, Christian,’ which is hilarious to me.”

The “House of the Dragon” star added, “But I mean, whose opinion do you really care about? If you’re pissing the right kind of people off, you’re doing OK.”

Alcock’s comments were met with further criticism online.

“And are those dads gonna take their daughters to see this movie after getting insulted? I know I’m not. And my daughter loved Supergirl,” one person tweeted last week.

“Pointing out that your critics are good dads is not a winning message,” another fan said.

A third person added, “No one is going to watch this movie now.”

Some fans also compared Alcock to “Snow White” actress Rachel Zegler, who sparked backlash last year when she described the original 1937 movie as “dated,” called Prince Charming a “stalker” and penned an anti-Donald Trump post on social media.

Zegler’s version of the classic fairytale bombed at the box office, which many attributed to her comments.

“Supergirl” flies into theaters June 26.
