Brad Pitt Heads Back to San Sebastián With David Ayer’s Heart of the Beast

This isn't Brad Pitt and David Ayer's first trip into dangerous territory together.

Ayer previously directed Pitt in 2014's Fury, the brutal Second World War drama in which Pitt played tank commander Don "Wardaddy" Collier.

More than a decade later, they're working together again, although Heart of the Beast swaps the claustrophobic interior of a Sherman tank for the enormous emptiness of the Alaskan wilderness.

Ayer's career has frequently gravitated towards characters operating under pressure. His filmography includes End of Watch, Fury, Suicide Squad, The Beekeeper and A Working Man.

Heart of the Beast appears to take that instinct and reduce it to something particularly elemental: survival.

Pitt plays James Belmont, a former Special Forces officer who survives a devastating plane crash alongside his combat dog, Odin.

Unfortunately, surviving the crash is merely the beginning.

The pair are left stranded deep in Alaska, where they must endure the wilderness and its dangers to stay alive.

Paramount describes the movie as an adventure thriller centred on the bond between Belmont and Odin as they battle the elements together.

It's a wonderfully uncomplicated setup.

There doesn't need to be a conspiracy, a city to save or a glowing object capable of destroying the planet. Put Brad Pitt in the wilderness with a dog, make getting home almost impossible and see how long the two of them can survive.

Sometimes that's all a thriller needs.

And the relationship between Belmont and Odin may ultimately prove more important than the spectacle surrounding them. The official synopsis repeatedly emphasises their connection, suggesting this isn't simply a survival movie with a dog conveniently along for the adventure.

The festival's official listing confirms J.K. Simmons and Anna Lambe, with Cameron Alexander writing the screenplay.

The film runs for 101 minutes, which is also encouraging for this kind of story.

A survival thriller doesn't necessarily need two and a half hours of mythology surrounding it. A tight hundred minutes of escalating problems, dangerous terrain and Pitt trying to keep himself and Odin alive could be exactly the right shape for the material.

Pitt also works behind the camera as a producer, alongside Olivia Hamilton, Marty Bowen, and Ayer.

The timing makes the festival appearance particularly interesting.

San Sebastián runs from 18 to 26 September, while Paramount currently has Heart of the Beast opening in cinemas on 25 September 2026.

That places the festival screening right in the film's theatrical launch window.

And although Heart of the Beast is part of the Official Selection, it will not compete for the festival's awards. Instead, it joins the programme as one of the selection's three out-of-competition films.

For audiences, however, Pitt and Ayer appearing together should ensure its screening becomes one of the festival's more visible events regardless of whether there's a prize at stake.

There's something increasingly appealing about a movie whose premise you can explain without a diagram.

Plane crashes.

Man survives.

Dog survives.

They're stranded in Alaska.

Get home.

That's your movie.

Of course, execution is everything, but Pitt remains one of those increasingly rare stars capable of making a relatively simple premise feel like an event. Pairing him again with Ayer also makes sense: Fury demonstrated that both are comfortable working with characters being ground down by hostile environments.

The dog changes the equation considerably.

If Heart of the Beast successfully makes us care about Belmont and Odin as a partnership rather than simply using the animal as a narrative device, Ayer has an obvious emotional pressure point to exploit.

And yes, we're already preparing ourselves for approximately 101 minutes of worrying about Odin.

Brad Pitt doesn't need another franchise to make an interesting movie.

In fact, Heart of the Beast sounds appealing precisely because its ingredients are so basic: one recognisable movie star, one director who knows his way around muscular thrillers, an unforgiving location and a relationship audiences can understand immediately.

Its San Sebastián appearance will now give the film a high-profile European showcase just as it begins reaching cinemas.

Seventeen years after Pitt last arrived at the festival alongside Quentin Tarantino, he'll return with David Ayer and a very different kind of film.

No Nazis. No tanks. No superheroes.

Just Brad Pitt, the Alaskan wilderness and a dog called Odin.

We're in.
