Paranormal Activity 3

Set in 1988, two sisters named Katie and Kristi find themselves living with their mother Julie and her partner Dennis. The family begins to notice strange, unsettling happenings around the house and decide to document what they experience on camcorders and home video equipment. The events appear to be tied to an unseen force that seems to stalk the rooms, move objects, and whisper in the walls, especially when the girls are alone. As the hauntings escalate, the sisters' bond and memories become entangled with the presence, forcing the family to confront a danger that refuses to stay hidden.

Released in 2011, Paranormal Activity 3 was directed by Henry Joost and Ariel Schulman, with the concept from Christopher Landon, and stars Katie Featherston and Sprague Grayden as the sisters.

Its worldwide gross reached 207,039,844 against a modest 5 million budget, reflecting strong audience turnout for the series in theaters worldwide.

Paranormal Activity 3 helped rekindle interest in low budget horror built around real looking footage. The film reinforced the idea that fear can be built through suggestion rather than gore, and its quiet, domestic setting spawned imitators and inspired later paranormal thrillers.

Critics praised the film's restraint and the documentary style, though some noted repetitive setup. Thematically, it centers on household fear, the fragility of family life, and how the unknown can intrude when everyday spaces feel safe.
