The Julia Set Brings Maths Prodigy Story to TIFF Without a Buyer

The Julia Set came to Toronto without a release deal in place. That leaves the next step as a sale, not a release date.

The film is the feature debut of writer-director Niki Byrne, meaning her first full-length film as a director, and it stars Chase Infiniti as Julia, a maths prodigy, as reported by Variety. It held its World Premiere, the first public screening anywhere, at the 2026 Toronto International Film Festival, according to TIFF. The festival lists it as a 2026 film from the United States of America, and a World Premiere tag signals the film had not been shown publicly before, which festivals prize for launches.

It still needs a buyer. As of its premiere week, the film was shopping for distribution, the industry term for finding a company to release it in cinemas or on streaming, as reported by Variety. That is common for independent titles at festivals, where a premiere is used to spark interest among distributors. Until a deal is signed, there is no date on the calendar for cinemas or home viewing.

In the story, Julia is recruited by an organised study group preparing for the Putnam Test, a demanding university-level maths contest. Christopher Briney plays Pascal, Julia's teaching assistant, the postgraduate who helps lead undergraduate classes, as reported by Variety. The festival describes Infiniti's character more simply as a gifted university student, according to TIFF.

Byrne wrote the script during COVID lockdown, as reported by Variety. She had returned to California from Europe in 2018 to work in Los Angeles and pursue writing and directing. The timeline points to several years of development from page to premiere, with lockdown writing followed by a long build to production.

The lead casting has deep roots. Infiniti first met Byrne three years before the Toronto interview, when Infiniti was a month into shooting Presumed Innocent, as reported by Variety. That meeting came well before the festival spotlight. Variety spoke to Byrne and Infiniti together in Toronto during TIFF 2026 about the project and its launch, marking their return together with a finished film. Toronto interviews during the festival are a standard launch moment for such titles.

For audiences, this means waiting for release news. Sales discussions can take weeks or months after a festival bow, as buyers weigh reaction, cast and a clear audience before making offers. What makes this one to watch is its starting point: a first-time director, a young lead centred as a prodigy, and a world premiere that places both in front of buyers at once.
