The recent release of the film 'Supergirl' has prompted discussions regarding its reception, with a new report from The Hollywood Reporter shedding light on the production process.

The report details alleged creative differences between director Craig Gillespie and producer James Gunn, suggesting they "were not creatively aligned." While some sources downplayed these issues as standard, others indicated a more significant divergence in vision.

By the time filming concluded in May 2025, Gillespie and the studio reportedly recognized the film needed adjustments.

This led to script revisions, with James Gunn enlisting writer Jeremy Slater to collaborate with original writer Ana Nogueira on punching up the script, which included reconfiguring the final fight sequence.

Test Screenings and Editorial Decisions

The report highlights that 'Supergirl' underwent four test screenings, a phase where significant decisions were reportedly made.

The film had two editors: Fred Raskin, who has previously worked with Gunn on projects like 'Peacemaker' and the 'Guardians of the Galaxy' trilogy, and Tatiana S.

Riegel, Gillespie’s longtime editor for films such as 'Cruella' and 'I, Tonya'.

Scores for the film reportedly improved with each new cut.

However, Warner Bros.

(WB) then reportedly opted to test two distinct versions against each other: a cut made during post-production by the studio and Gillespie’s own version.

Gillespie's cut was said to be 11 minutes longer and reportedly scored higher in categories such as villain portrayal, song choices, and pacing.

Despite this, the WB-made cut was ultimately chosen for theatrical release, reportedly due to an overall higher score by two points.

An unnamed source, experienced in franchises but uninvolved with 'Supergirl', commented that while such situations occur, it is "not normal" for a studio to invest in the test process and then disregard certain outcomes.

Following these test screenings, the film was reportedly not tested again, and Gillespie allegedly had to personally advocate for his preferred elements to be included.

Notably, the controversial inclusion of a cover of Jimmy Eat World’s “The Middle” during an action scene near the end, as well as Cindy Lauper’s “Girls Just Want to Have Fun,” were reportedly suggestions from Gunn.

As 'Supergirl' marks the second major release in the new DC movie slate, its performance carries particular weight for the franchise's trajectory.

Despite the reported challenges, other DC projects are moving forward, including 'Clayface' set for October and 'Man of Tomorrow', starring Milly Alcock, slated for July 2027.

Gunn's influence is expected to continue, with a Jimmy Olsen comedy spinoff, 'DC Crime', and a Mr.

Terrific spinoff from 'The Sandman' writer Allan Heinberg reportedly in "active development."
