Milly Alcock is set to reprise her role as Kara Zor-El in the upcoming DC Universe film Man of Tomorrow, marking a significant expansion of her character following her debut in James Gunn’s Superman. As DC Studios co-CEOs James Gunn and Peter Safran continue to build their interconnected franchise, Alcock’s Supergirl is positioned as a central figure in future Earth-based narratives.
Milly Alcock’s Role in the DC Universe
Following her appearance in the 2025 Superman film, Milly Alcock will play a major role in the sequel, Man of Tomorrow. James Gunn confirmed to Extra that the filming schedule for the project is demanding, requiring Alcock to balance production commitments with international promotional work.

While specific plot details for Man of Tomorrow remain under wraps, the film is expected to feature a team-up between David Corenswet’s Superman and Nicholas Hoult’s Lex Luthor to face a significant threat, widely reported to be the extraterrestrial antagonist Brainiac. The inclusion of Supergirl in this narrative suggests a more collaborative approach to the "Kryptonian" dynamic within the new DCU, moving away from the isolated storylines often seen in previous iterations of the character.
Expanding the DCU Narrative
The integration of Supergirl into the broader DCU is part of a deliberate strategy by DC Studios to create a cohesive shared universe. Lars P. Winther, an executive producer on Supergirl, stated in an interview with The Hollywood Reporter that Alcock is slated to appear in at least one additional, currently unannounced DCU project.
This multi-film arc aims to contrast with the character’s origins in the Supergirl: Woman of Tomorrow comic series, which primarily takes place in deep space. By transitioning the character to an Earth-based setting, the studio is aligning her story with the central conflict involving Superman and his supporting cast. This shift mirrors the studio’s broader development strategy, which includes a new Wonder Woman project currently in early development.
Comparison of DCU Production Timelines
Warner Bros. and DC Studios have adopted a measured release strategy for their new slate. Unlike the rapid-fire release schedules of the previous decade, the current leadership is prioritizing individual character development before larger ensemble pieces.

|---|---|---|
| Superman | Released (2025) | Clark Kent’s early years |
| Supergirl | Released (2025) | Kara Zor-El’s journey to Earth |
| Man of Tomorrow | In Development | Superman and Supergirl team-up |
