Brad Pitt did not set a Rotten Tomatoes record and his new film is not at 100 per cent

Brad Pitt spends most of Heart of the Beast alone in a forest with a German shepherd. The marketing has spent the last 72 hours doing something considerably busier.

MovieWeb ran the film as "Officially One of the Year's Best After Perfect Rotten Tomatoes Debut." ScreenRant went further, reporting that Pitt and director David Ayer had "officially set an all-time Rotten Tomatoes record." Paramount opens the film wide on 25 September, and both headlines are doing work that the underlying number cannot support.

The underlying number is 92%.

Ninety-two per cent is not a hundred, and Rotten Tomatoes does not keep an all-time record

As this was written, Heart of the Beast sat at 92% on 38 reviews, with no verified audience ratings yet logged. That is thirty-five positive notices and three negative ones. It is a good opening-week score. It is not perfect, and the word "perfect" has a specific meaning on an aggregator that publishes the exact count.

The second claim is stranger, because the category does not exist. Rotten Tomatoes ranks films by Tomatometer and publishes guides that do so. It does not maintain an "all-time record" that a September release can set. What a 92% on 38 reviews means in practice is that four rotten reviews in the next twenty would drop the film below 85%, which is where Ayer's best-reviewed previous film has been sitting for thirteen years on a sample nearly five times larger.

That film is End of Watch: 85% from 181 reviews. The comparison is the entire story, and it is a better one than the headlines. A director whose career high was 85% has opened at 92%. The honest caveat is that 38 reviews is a third of the sample, and opening-week scores move.

The script sat on a list for seven years before a director wanted it

Cameron Alexander's screenplay landed on the 2017 Black List, the annual survey of unproduced scripts that industry executives liked most. Ayer signed on in March 2024.

Seven years is not unusual for a Black List title, but it does deflate the "hot script" framing that tends to accompany them. The Black List measures how many people read something and enjoyed it. It does not measure whether anyone wanted to pay for it.

What is actually confirmed about the film

• Paramount Pictures releases it wide on 25 September 2026, running 1 hour 41 minutes.
• Directed by David Ayer from a screenplay by Cameron Alexander, which appeared on the 2017 Black List.
• Brad Pitt plays James Belmont, a former special forces operative who survives a plane crash in the Alaskan wilderness with his military dog. J.K. Simmons joined in February 2025, Anna Lambe in March.
• The dog, Odin, is played by an animal actor credited as Uber.
• Principal photography ran 3 March to 15 May 2025 — in Queenstown, New Zealand, not Alaska.
• Produced by Wild Chickens Productions, Pitt's first-look company at Paramount, with Temple Hill Entertainment and Kino World.
• The first trailer premiered at CinemaCon in April 2026.
• It screened out of competition at the 74th San Sebastian International Film Festival, which closes this Saturday.
• Composer Jared Michael Fry is on his third Ayer film.
• It is Ayer's first film with Pitt since Fury in 2014.

The forecasts have a six-million-dollar spread two days out

Boxoffice Pro's long-range projection, filed in late August, put the opening at $15–25 million and noted that Ayer's last two films opened in the mid-teens. Boxoffice Theory's 23 September forecast narrowed it to $14–19 million. Independent tracker Todd Thatcher put it at $15.7 million.

That is a $6 million gap between trackers on the same three days, for a film opening against a DreamWorks animated release, an A24 wide release and a re-release of the third-highest-grossing film ever made. Nobody publishes a budget for Heart of the Beast, so there is no threshold to measure the opening against — which has not stopped anyone from writing about whether it will clear one.

What is still unknown

The budget. The final Tomatometer, which will have moved by Sunday. Whether audiences turn up for a survival drama with one human lead and a dog in a market where the same weekend offers a family animation and a Marvel re-release with Infinity Vision screenings attached.

And whether the 92% holds. If it does, Ayer has the best reviews of a thirteen-year directing career. If it slips four points, he has matched End of Watch on a fifth of the sample, and the "record" headlines will already have done their work.

A 92% is a real achievement for a director who has spent a decade being reviewed as a stylist with a problem. It is a shame the people selling it could not leave it alone.
