I See You has all the makings of an excellent thriller, including a cast consisting of established Hollywood stars and up-and-coming talent. The 2019 movie follows a detective investigating a mysterious disappearance while seemingly supernatural events begin to happen to his family. Following its premiere at the South by Southwest Film Festival, I See You was released on VOD in the U.S. without theatrical distribution. Fortunately, I See You's true story connection and realistic nature make the movie more frightening than a typical straight-to-video horror film, and it's become a modern horror cult classic.

Critics also praised I See You, particularly in recognition of its actors, with veterans like Helen Hunt elevating the movie beyond the restrictions of the indie horror genre. Its expertly crafted narrative unfolds with unquestionable tension, and the performances from the cast help to sell every twist and turn that the movie throws at the audience. Here's a guide to the I See You cast, which character each actor plays, and what other roles they're known for.
