Rose Byrne and Jenna Ortega to star in Mary Bronstein's 'Nasty' for Warner Bros.' Clockwork banner

Warner Bros. has tapped Mary Bronstein to direct "Nasty," a sports drama that will pair Rose Byrne with Jenna Ortega and release under the studio's new indie banner, Clockwork, Variety reported on 16 July 2026. The casting reunion with Byrne, who starred in Bronstein's A24 title "If I Had Legs I'd Kick You," is the engine of the project's news appeal. The script, from Black List writer Isabel, is the project's first public creative credit.

The pairing lands at a moment when major studios are quietly rebuilding their prestige pipelines around boutique labels. Clockwork's commissioning of "Nasty" is the clearest signal yet of how Warner Bros. intends to use the imprint: established auteur directors, mid-budget genre pieces, and casts that can carry awards-friendly positioning without the studio's superhero overhead. Ortega, fresh off her run as the studio's principal Wednesday Addams, brings built-in audience pull. Byrne brings the festival-to-Oscar-trail currency that A24 minted with her prior Bronstein collaboration. The film positions itself to occupy the slot that Fox Searchlight and A24's mid-budget divisions owned through the late 2010s.

What's actually been announced

The public reporting on 16 July 2026 names the principals and the buyer. Rose Byrne and Jenna Ortega are attached to star, Mary Bronstein is directing from her own project, and Warner Bros.' Clockwork is producing and will distribute, according to Variety. Indiewire's same-day report identifies the script as originating on the Black List and credits writer Isabel; Indiewire's wire also confirms that Clockwork is the production banner inside Warner Bros. The package, in other words, is built: a director with a recent auteur credit at a rival studio, two stars with distinct audience demographics, and a Black List script that cleared the development-stage filter.

What the disclosures do not yet include is a start date, a release window, a budget bracket, or character names. Variety's reporting calls the film a "sports drama"; the studio has not specified the sport. Bronstein's prior work is relationship-driven psychological drama with bodily and maternal themes, which suggests the athletics will be character interior as much as competition footage, but the source material is silent on that read.

The Clockwork bet

Clockwork is the most concrete answer yet to a question the major studios have been answering unevenly since 2024: how does a conglomerate with a comic-book tentpole habit produce the kind of mid-budget, director-driven film that reliably delivers prestige without breaking the budget ledger? Warner Bros.' solution is to wall off a sub-label with its own commissioning logic, much as Universal revived Focus Features and Sony held onto Sony Pictures Classics through the streaming consolidation. "Nasty" is the kind of project that could plausibly have lived at A24, Searchlight, or Neon, all of which have spent the last three years harvesting exactly this register of mid-budget drama. The fact that Warner Bros. is competing in that lane internally, rather than letting the film migrate to a competitor, is a market signal worth watching.

For Bronstein, the move continues a working relationship that A24 launched. "If I Had Legs I'd Kick You" gave Byrne the kind of unsentimental, physical performance that critics reward and that the Academy's actress branch has, in recent cycles, favoured over sympathetic-drama defaults. The presence of Ortega broadens the audience without diluting the register: Ortega has demonstrated, across "Wednesday" and her horror credits, that she can carry a tone. Pairing the two is a casting decision that assumes both registers can coexist without one flattening the other.

What stays opaque

The story as filed is a package announcement, not a production disclosure. Three pieces of context are not in the public reporting: the shoot schedule, the full producing team behind Clockwork for this project, and the financial terms of the Black List script acquisition. None of that is unusual at greenlight-stage press, but it does mean the more interesting structural questions (whether Clockwork is buying outright or producing on a reduced backend, whether the film will be a day-and-date streaming release or a theatrical-first title) cannot yet be answered from the reporting.

A second open question is the script's genre orientation. Indiewire's reporting characterises "Nasty" as a sports drama through a Black List premise; Variety's angle leans on the Byrne–Bronstein reunion. Whether the eventual film tracks closer to the athletics premise the trades have flagged, or to the relationship-and-body terrain of Bronstein's prior work, will determine which of those two audiences the project actually serves. The sources do not specify.

The stakes, in plain terms

If Clockwork delivers "Nasty" as a 2027 festival title and Byrne lands the kind of notices she drew for "If I Had Legs I'd Kick You," the studio will have its first data point that the boutique-banner experiment can mint the awards-season currency its predecessors produced. If the film slips into streaming-only release and lands without a festival footprint, the lesson will be that prestige positioning inside a major-studio subsidiary is harder than the press release implies. The next twelve months of greenlights will tell readers which way the wind is blowing.

Desk note: Monexus is framing this as a greenlight announcement with structural stakes for Warner Bros.' boutique-banner strategy, not as a casting story. The wire led on the Byrne–Ortega pairing; this publication is treating the Clockwork commission as the news.
