James Gunn's reintroductory Man of Steel movie has taken flight again. Mere days before Kara-Zor-El propels herself through the planets, Gunn's Superman (2025) has shot up on Prime Video charts. Supergirl is the next major chapter in James Gunn’s revamped DCU. This high-energy space-faring adventure expands the Gods and Monsters chapter by introducing Milly Alcock’s Girl of Steel as the renewed franchise’s first female lead.

The film follows directly after the events of Superman, which relaunched the entire universe with David Corenswet’s Kal-El at its heart, and now sets the stage for a broader, more interconnected superhero saga.

But before Supergirl hits theaters, the original tentpole that kicked off this entire DCU reboot is suddenly surging again on streaming.

Just days before Supergirl’s June 26 worldwide premiere, Superman is experiencing a strong resurgence on Prime Video. The film has climbed back into the platform’s top 10 most-streamed titles in the United States, reflecting a renewed wave of audience interest. Viewers seem to be returning to revisit the foundation of the new DCU timeline.

Part of that momentum comes from curiosity around Kara Zor-El’s introduction. Fans are revisiting Superman to catch early connective threads and better understand how Supergirl will build on that groundwork. The strategy mirrors the kind of interconnected viewing habits that have defined major franchise storytelling in recent years.

The numbers also underline the film’s lasting appeal after its theatrical success, where it crossed $600 million globally. Streaming has extended its lifecycle, allowing it to function as both a standalone story and a launchpad for future installments. The renewed traction signals that audiences are staying engaged with the evolving DCU.

That renewed attention now feeds directly into how Supergirl is being positioned just days before release.

Despite being framed as a standalone introduction for Kara Zor-El, Supergirl is undergoing notable changes as it nears release. The film’s runtime has been reduced to 1 hour and 47 minutes, including credits, making it significantly shorter than earlier over 2-hour-long cuts. This tightening points to a more focused narrative approach.

However, the most telling adjustment is the addition of new material featuring David Corenswet as both Clark Kent and Superman. Even as the film becomes more concise, Superman’s role within it appears to be expanding. That shift indicates a strategic emphasis on the franchise’s central figure.

What emerges is a film that may be evolving beyond its initial concept. While Supergirl remains Kara’s origin story, the increasing prominence of Superman suggests a broader narrative alignment with the DCU’s core direction. As the release date approaches, the conversation is shifting from expectations to execution, and the steady streaming numbers are only pawns in the big picture.
