James Gunn’s Superman has become 2025’s highest-grossing superhero movie, a major win for DC Studios and a promising boost for the DCU’s next big release—Supergirl.
According to Box Office Mojo, Superman has earned $510.8 million globally so far, outperforming all of Marvel’s 2025 entries, including Captain America: Brave New World ($415.1M), Thunderbolts ($382.3M), and The Fantastic Four: First Steps ($241.3M and still in theaters).
Superman, starring David Corenswet, serves as the official launch of the DCU’s Chapter One. Its impressive box office performance is critical not only for franchise momentum but also for upcoming projects tied to this universe. One major beneficiary is Supergirl, set for a 2026 release.
Milly Alcock’s Supergirl made a surprise cameo in Superman, revealing her as the owner of Krypto and teasing her solo storyline. This early introduction has sparked strong interest in her character, making her the most connected DCU hero after Superman.
Adding further firepower to Supergirl’s box office potential is Jason Momoa, who joins the cast as Lobo, a fan-favorite bounty hunter. Momoa’s proven track record includes Aquaman ($1.15B) and Minecraft ($955.1M), establishing him as a reliable box office draw.
With Superman soaring above expectations, Supergirl is now well-positioned to ride that momentum. Between Alcock’s debut, strong franchise connections, and Momoa’s star power, Supergirl could become the next major hit for the revitalized DCU.
