: While there are currently no verified "free" legal streaming options for the 2019 original, its 2021 sequel is sometimes available for free on iQIYI .

Downloading the official international versions of these streaming apps frequently grants access to a massive library of Asian horror films. Many titles are free to watch with ad support, or require a very affordable monthly subscription.

: Unauthorized downloads often rely on automated machine translations or poorly synchronized user-generated subtitles, which can ruin the viewing experience.

: Available for rental or purchase, sometimes included with a Hi-YAH! channel add-on iQIYI Movie English channel
