Ian Tuason

Ian Tuason is a Canadian filmmaker and author. He is known for writing and directing the horror film Undertone.

Life and Career Ian Tuason was born in Montreal, Quebec, Canada and started his career directing a number of short films in the 2010s, but was forced to put his career on hold for a time in the early 2020s to care for his parents after they were both diagnosed with cancer. The original concept for Undertone began as a radio play before being turned into a film screenplay that incorporated some of his own experiences during this era, using the unconventional narrative technique of conveying horror themes entirely through sound design.

In 2025, Tuason made his directorial debut with the horror film Undertone, which premiered on July 27, 2025 at the 29th Fantasia International Film Festival, where it won the gold audience award for Canadian films. It was released in the United States on March 13, 2026 by A24.

On December 12, 2025, it was announced that Tuason would write and direct the horror film Paranormal Activity 8, the eighth installment in the Paranormal Activity franchise. Jason Blum, James Wan and Oren Peli will serve as producers through their Blumhouse Productions, Atomic Monster, Solana Films banners, respectively, alongside Room 101, Inc. The film is scheduled to be released on May 21, 2027 by Paramount Pictures.

On April 9, 2026, it was announced that Tuason is developing a prequel film to Undertone for A24. It will be the second installment in a planned trilogy.
