The recently released DC film Supergirl experienced significant behind-the-scenes turmoil, with director Craig Gillespie and DC Studios reportedly being "not creatively aligned." This internal friction culminated in competing test screenings for two distinct versions of the film, according to a report from The Hollywood Reporter. While some sources suggest the disagreements were merely "healthy friction," the conflict necessitated DC Studios taking control of post-production.
Filming for Supergirl concluded in May 2025. Following a poorly received test screening in December of that year, DC Studios assumed responsibility for the editing process. The studio also enlisted Jeremy Slater, writer of Mortal Kombat II, to assist with revisions, though the extent of his involvement remains unclear. Notable changes included alterations to the climactic battle sequence and the film's music choices. The final version features an acoustic cover of Jimmy Eat World's "The Middle" by Kelty Greye and KidMotel, a choice that has drawn criticism. James Gunn, however, had reportedly advocated for a cover of Cyndi Lauper's "Girls Just Want to Have Fun."
Ultimately, DC Studios orchestrated a "bakeoff" between Gillespie's director's cut and the studio's version. Gillespie's cut was approximately 11 minutes longer and included more of the villain Krem. The studio's iteration, however, achieved scores roughly two points higher in test screenings, leading to its selection for theatrical release.
Despite these production challenges, the DC Universe slate remains on track. The horror film Clayface is slated for release later this year, with a Superman sequel scheduled for 2027.
