Warner Bros. undertook substantial revisions to its film release calendar on Wednesday, announcing a new premiere date for the much-anticipated cinematic endeavor by Paul Thomas Anderson featuring Leonardo DiCaprio.

Now officially titled “One Battle After Another,” this Anderson project remains cloaked in secrecy, though it is categorized as an American crime thriller. Originally scheduled for an August 8 debut, the film will now grace theaters nationwide on September 26.

Sources familiar with the production indicated that this slight postponement is intended to facilitate the installation of VistaVision projection systems in U.S. movie theaters, aligning with Anderson’s artistic vision. By shifting the release from the summer to late September, “One Battle” strategically avoids the competitive summer box office landscape while also positioning itself closer to the awards season—an arena where Anderson’s films often thrive. A studio insider noted that auteur-driven projects with commercial viability tend to perform well in this timeframe, citing successes like “Gravity” and “A Star is Born.” DiCaprio will share the screen with a stellar cast, including Sean Penn, Benicio Del Toro, Regina Hall, and Teyana Taylor.

In other developments on Warner Bros.’ slate, Maggie Gyllenhaal’s “The Bride!” has been rescheduled from this September to March 6, 2026. Featuring Christian Bale and Jessie Buckley, this steampunk interpretation of Frankenstein and his bride will benefit from a release schedule that avoids competition with Guillermo del Toro’s own adaptation, slated for Netflix this November. Industry insiders suggest that March has proven advantageous for the studio’s major releases, including entries from the “Dune” franchise and Legendary’s monster series.

Moreover, Director Zach Cregger’s follow-up to his acclaimed horror film “Barbarian,” now titled “Weapons,” has been advanced from a January 2026 release to August 8, taking the previous slot of “One Battle After Another.” This strategic move signals confidence in Cregger’s new multi-narrative horror epic, featuring Josh Brolin and Julia Garner, which is slated for a preview screening at Las Vegas’ CinemaCon at month’s end. “Weapons” will debut just a week after “Together,” Neon’s highly publicized horror acquisition from Sundance, starring Dave Franco and Alison Brie.

Another elusive project, “Flowervale Street,” headlined by Anne Hathaway, Ewan McGregor, and Maisy Stella, has been postponed from March 2026 to August 14, 2026. Very little information is available about this film, directed by David Robert Mitchell (“It Follows”) and produced by J.J. Abrams, aside from its 1980s setting and a plot centered on a family witnessing unusual occurrences in their seemingly idyllic neighborhood.

Finally, Warner Bros. Animation has decided to release “The Cat in the Hat” two weeks earlier than originally planned, now scheduled for February 27 next year. Featuring the vocal talents of Bill Hader and Quinta Brunson, this adaptation of the beloved Seuss classic is strategically placed to distance itself from the Pixar film “Hoppers,” which is set to premiere a week later.
