DC films in theaters on September 12, 2025 included Superman ; it was still in theaters that week and was widely discussed in September 2025 coverage.

What was playing

  • Superman (2025) — the main DC theatrical release around that date.

Important note

  • I could verify Superman from the available September 2025 coverage, but I can’t confidently confirm a longer full slate of DC titles in theaters on that exact day from the material I have.

Extra context

  • September 12, 2025 was also a notable movie-release date for The Long Walk , but that was not a DC movie.

TL;DR: The DC movie I could verify as in theaters on September 12, 2025 was Superman.
