In a recent television interview that sent shockwaves through the entertainment world, Milly Alcock, the rising star set to portray Supergirl in the upcoming DCU film Supergirl: Woman of Tomorrow, made a daring statement. The Australian actress, known for her breakout role in House of the Dragon, confidently claimed that her superhero flick could surpass the iconic Spider-Man franchise in next summer’s box office showdown. This bold assertion has sparked heated discussions among fans and industry insiders, raising the question of whether the Girl of Steel can truly swing past the web-slinger in cinematic success.
Alcock’s comments came during a lively interview with Extra TV, where she discussed the whirlwind experience of wrapping production on Supergirl: Woman of Tomorrow, set for release on June 26, 2026. “I think it’s actually gonna be a really good movie,” Alcock said, her excitement palpable. “We’ve got something special, and I genuinely believe we can take on anyone—even Spider-Man.” Her confidence is infectious, but it’s also a bold gamble, considering Spider-Man’s storied history of dominating the box office with its action-packed narratives and global fanbase.
The superhero genre remains a juggernaut in Hollywood, with films like Spider-Man: No Way Home grossing over $1.9 billion worldwide. Yet, Alcock’s claim isn’t without merit. The DCU, under the creative direction of James Gunn, is undergoing a transformative reboot, with Supergirl: Woman of Tomorrow positioned as a key player in the “Gods and Monsters” slate. Unlike its predecessor, the critically panned 1984 Supergirl film that earned just $14.3 million, this new iteration promises a gritty, cosmic adventure inspired by Tom King’s acclaimed comic series. The story follows Kara Zor-El on a vengeance-fueled journey through space, a stark contrast to the campy tone of past portrayals.
Industry analysts are intrigued by Alcock’s optimism. The positive reception to Gunn’s Superman, released in July 2025, has revitalized interest in DC’s cinematic universe. Box office discussions on platforms like Box Office Theory suggest that Supergirl could capitalize on this momentum, with projections estimating a potential $200-250 million domestic haul if reception remains strong. The film’s summer release, coupled with the star power of Alcock, Jason Momoa as Lobo, and Matthias Schoenaerts as Krem of the Yellow Hills, adds to its appeal. “There are some things in favor of Supergirl,” noted a Box Office Theory contributor. “The domestic audience still seems open to big DC movies, and the positive reception to Superman definitely helps.”
Alcock’s own journey to the role adds a layer of intrigue. In a June 2025 interview with Elle magazine, she revealed the intense emotions she felt upon landing the part. “I was kind of in disbelief,” she admitted. “I was initially like, ‘What have I done?’ I then invited all my friends over to the house and we drank champagne.” Her candidness about the pressures of stepping into a legacy franchise resonates with fans, humanizing the larger-than-life persona of Supergirl. This authenticity could be a key factor in drawing audiences to theaters.
On the other hand, Spider-Man remains a formidable opponent. The Marvel Cinematic Universe’s web-slinger has a proven track record, with each installment delivering high-octane action and emotional depth. The next Spider-Man film, expected to release around the same time as Supergirl, will likely feature Tom Holland’s Peter Parker navigating new challenges post-No Way Home. Marvel’s knack for crossovers and multiverse storytelling could give it an edge, especially with younger audiences who have grown up with the MCU.
Yet, Supergirl: Woman of Tomorrow offers something fresh. Directed by Craig Gillespie, known for I, Tonya and Cruella, the film promises a unique blend of emotional depth and cosmic spectacle. Early set footage leaked online in April 2025 showcased Alcock’s Supergirl in intense battle sequences, hinting at a visually stunning experience. The inclusion of Krypto, Supergirl’s loyal canine companion, adds a heartwarming element that could broaden its appeal.
As the summer 2026 box office battle looms, Alcock’s bold claim has ignited curiosity. Can Supergirl: Woman of Tomorrow truly outshine Spider-Man? The answer lies in the execution—strong storytelling, compelling performances, and audience reception will be key. For now, Alcock’s confidence has set the stage for an epic showdown, and fans are eagerly awaiting the chance to see if the Girl of Steel can soar to new heights.
