Josh Heuston is trading the world of high society for the high-octane world of Formula 1. The Australian actor has been tapped to headline Amazon MGM Studios’ adaptation of Lauren Asher’s wildly popular novel Throttled, the first installment in the author’s bestselling Dirty Air series. The project, which has been simmering in development since the studio acquired the rights to the literary phenomenon, now has its leading man in place.
While plot specifics have been kept under the hood, those familiar with the source material know that Throttled centers on the combustible relationship between Maya Alves and Santiago “Santi” Alonso. She’s an aspiring social media influencer who lands a job working with one of the most dominant - and notoriously difficult - drivers on the Grand Prix circuit. He’s a champion with a reputation for being as fast on the track as he is emotionally distant off it. The friction between them is immediate, electric, and, of course, blossoms into something far more complicated than a professional arrangement. Heuston, who has yet to book a major studio feature of this scale, will now bear the considerable weight of playing a character beloved by millions of readers, a challenge the actor seems ready to embrace.
The casting marks a significant coupe for Heuston, who has been steadily building a resume since breaking out in the second season of HBO’s Industry. In that role, he played a privileged and slightly lost London trustafarian with a veneer of charm that barely concealed a deeper insecurity - an audition of sorts for the kind of internal conflict a role like Santi demands. He followed that with a turn in the star-studded The Perfect Couple on Netflix, where he more than held his own against a veteran ensemble. But Throttled is a different beast entirely. It's a role that requires leading-man magnetism, a brooding physicality, and the ability to sell a romance that hinges on two people who would rather die than admit they’re falling for each other. It's a classic movie-star template, and the studio is clearly betting that Heuston has the charisma to fill it.
For the uninitiated, the Dirty Air series has become a cornerstone of the modern romance boom, a subgenre that thrives on tropes we can't resist: enemies-to-lovers, forced proximity, and a hero who needs saving from himself. Asher’s books have sold in massive numbers, particularly among readers who devour them on Kindle and TikTok’s BookTok community, where clips of spicy quotes and fan edits routinely go viral. That built-in audience is a major reason why Amazon MGM moved quickly to secure the rights. A dedicated fanbase that already has a visual and emotional connection to the characters is a producer's dream, offering a guaranteed opening weekend audience without a dollar spent on marketing to them.
However, adapting a book with such a passionate following is a double-edged sword. The same readers who will buy tickets on day one are the ones most likely to scrutinize every casting decision, every costume choice, and every line of dialogue. The pressure is on screenwriters to capture the essence of the dynamic between Maya and Santi, a workplace romance that feels modern and grounded despite the glamour of the setting. The hope is that Heuston brings the same alchemy to the screen that made Asher’s words so compelling on the page: a sense of peril, both physical and emotional.
The choice to place the film at Amazon MGM is strategically sound. The studio has had enormous success with star-driven, romance-adjacent projects that appeal to a broad, streaming-savvy demographic, and they have the infrastructure to release a film both theatrically and on Prime Video, maximizing its reach. With Formula 1's popularity surging in the United States, largely thanks to the Netflix documentary series Drive to Survive, the setting itself offers a ready-made backdrop of tension and adrenaline that elevates the material beyond a simple love story.
Heuston now joins the ranks of young actors tasked with translating literary heartthrobs for the big screen. It's a high-wire act, balancing the expectations of purists with the need to create a compelling cinematic experience for newcomers. Early buzz suggests he fits the physical bill, but the real test will be whether he can make Santi's gruff exterior belie a wounded interior without tipping into caricature.
As production gears up to begin in the coming months, Hollywood will be watching closely. Throttled has all the ingredients for a franchise-launching hit, and with the Dirty Air series offering three more novels - including Collided and Twisted - a successful debut could open the door for a new cinematic universe built on the back of one of publishing's hottest properties. For now, the engines are revving and the starting grid is set with a new driver at the wheel. Whether Heuston crosses the finish line as a breakout star remains to be seen, but he's certainly in pole position for the opportunity of a lifetime.
