LOS ANGELES — Helen Slater spent four months trampolining, fencing, and gaining 15 pounds of muscle to play Supergirl in 1984. Her film earned $14 million domestically, and Warner Bros. cancelled the two sequels she had contracted to make. When Milly Alcock’s version of the same character opened last weekend to $38 million, Slater did not equivocate.
She called Alcock astonishing.
“I loved the new Supergirl film,” Slater told The Hollywood Reporter on Thursday, describing Alcock’s performance as “fierce, strong and great comic timing.” The praise arrived with a weight no studio publicity department could replicate: not from a competitor or a publicist, but from a woman who had stood in the same position 42 years earlier and watched the franchise collapse around her film debut.
DC Studios co-CEO Peter Safran offered the official response. “While Supergirl didn’t meet our box office expectations,” he said, as The Hollywood Reporter reported, “it’s just one component of a broader, long-term strategy at DC Studios that we remain confident in.”
That broader strategy is the joint project of Safran and DC Studios co-CEO James Gunn: a deliberate long-cycle reboot of the DC Universe built on connective tissue rather than the standalone boom-or-bust model that characterized Warner Bros.’ pre-Gunn output. Supergirl, directed by Craig Gillespie, was the second major film in that slate, following Superman, which grossed $618 million globally last year on a $225 million budget. Alcock’s film opened to $68 million globally on a $170 million budget. In a different era of studio management, that discrepancy would trigger a restructure. In the Gunn-Safran model, it produced a statement of confidence.
Whether that confidence is strategic or performative will become clearer with the films that follow. Analysts have projected the total loss at between $85 million and $125 million, a figure accounting for production costs, global marketing spend, and expected theatrical trajectory. The domestic result makes Supergirl the weakest opening in the current DCU slate, sitting below even Joker 2, which was broadly considered the most commercially disappointing entry in Warner Bros.’ Elseworlds strand and still outperformed this opening weekend.
Alcock, an Australian actress who built her profile through the HBO series House of the Dragon before being cast as Kara Zor-El, generated controversy before the film even opened. Comments she made about her character’s religious background circulated widely online in the weeks ahead of the premiere and became the dominant pre-release conversation. Whether those comments materially dampened ticket sales or whether the film faced structural audience resistance of a different kind is a question the opening weekend data does not cleanly settle. She has not addressed the box office result publicly.
The entertainment industry has spent much of 2026 in an uneasy negotiation with its own legacy characters and the performers who originally inhabited them. Questions about AI-reconstructed voices and franchise revivals have run through the entertainment press all year, reshaping how studios think about what they owe the performers who defined their most durable properties. Slater’s remarks arrive in that context, with an unusual authority: her connection to the Supergirl character ended abruptly after 1984, through no choice of her own, and she built a subsequent career in television and theatre largely without revisiting the role.
The original Supergirl film, directed by Jeannot Szwarc, was a critical and commercial failure. The parallel between the two Supergirl openings spans four decades but remains otherwise intact: debut performance, box office shortfall, cancelled franchise continuation. What diverges is the response from the performer at the centre of the earlier disappointment. Rather than offer the careful non-comment that public relations protocol tends to produce in these circumstances, Slater offered unqualified admiration for the actress who took the role after her.
What DC Studios does with Alcock going forward is an unanswered question. Clayface, a body-horror adaptation starring Tom Rhys Harries, is scheduled for October 2026. Man of Tomorrow, the Superman sequel, arrives in July 2027. Animated and prestige television productions, including Creature Commandos and Lanterns, are in active development. The slate has sufficient forward momentum that a single underperforming debut does not demand an immediate architectural response. Whether it changes the calculus around Alcock’s role in future productions, whether a standalone sequel is quietly shelved or whether she appears alongside David Corenswet’s Superman in Man of Tomorrow, remains publicly unaddressed.
What the studio has offered is confidence. What the actress at the centre of the story received, from an unexpected quarter, is something more durable: the endorsement of someone who knows what a Supergirl box office disappointment looks like from the inside and chose, despite it, to say the performance itself was worth watching.
