Knock Knock - Collectors Edition Digipak (4K Ultra HD + Digital)

Celebrate the 10th anniversary of Knock Knock with a premium Collector’s Edition Digipak (4K Ultra HD + Digital)—presented in Dolby Vision and featuring new special features available in the U.S. for the first time. Directed by Eli Roth, this tense, seductive home-invasion thriller stars Keanu Reeves, Ana de Armas, and Lorenza Izzo, and arrives in striking paper-based packaging with riveting, emotional art by acclaimed illustrator Krzysztof Domaradzki.

On a stormy night, devoted family man Evan (Keanu Reeves) is home alone when two stranded, mysterious young women (Ana de Armas, Lorenza Izzo) appear at his door asking for help. One seemingly harmless act of kindness becomes a nightmare as Evan is trapped inside his own home—pulled into a sadistic, twisted game of seduction, manipulation, and temptation that spirals far beyond his control.
