Ian Tuason is a Filipino-Canadian director and author. He is best known as the director of the horror film "Undertone" (2025).

He is also known for his live-action virtual reality shorts and first-person horror films, including "Sit Back," "Uncanny Valley," and "Experience: Colorblind," which together have amassed millions of views online. In 2025, it was announced that Tuason would team up with James Wan and Blumhouse for the eighth installment of the "Paranormal Activity" series, marking his transition from digital and VR horror to a major theatrical release. This is a natural evolution for Tuason, as his work is defined by first-person perspective, diegetic sound, and minimalist environments, placing viewers directly inside the horror rather than observing it — an approach closely aligned with found footage's emphasis on immersion and authenticity.
