Supergirl is the second film in which shared universe?

Supergirl is the second film in the DC Universe, the shared continuity launched by DC Studios under James Gunn and Peter Safran. It follows Superman (2025), which introduced David Corenswet as the new Superman and established the film series’ initial big-screen direction.

The DC Universe, often shortened to DCU, replaced the DC Extended Universe as the primary connected movie continuity. The DCEU included films such as Man of Steel, Wonder Woman, and Aquaman, but Supergirl is not part of that earlier franchise. Likewise, it is separate from the Arrowverse, the television continuity associated with shows including The Flash and Supergirl.

Supergirl expands the DCU beyond Earth with a cosmic adventure involving Kara Zor-El, Ruthye, Krem, Lobo, and Krypto the Superdog. Its story draws on Supergirl: Woman of Tomorrow while remaining a new cinematic interpretation. The phrase “second film” refers to the DCU’s theatrical film sequence, not the second movie ever made about Supergirl or the second DC Comics adaptation overall.
