P2 (2007)

P2 is a 2007 American psychological horror film directed by Franck Khalfoun, in his directorial debut, co-written by Khalfoun and producers Alexandre Aja and Grégory Levasseur, and starring Rachel Nichols and Wes Bentley. Its plot follows a young businesswoman who becomes trapped in an underground parking garage in midtown Manhattan on Christmas Eve, where she is pursued by a socially awkward, psychopathic security guard who is obsessed with her.

Following the release of their film High Tension (2003), Aja and his co-writer on that film, Levasseur, developed the screenplay for P2 alongside Khalfoun, inspired by a series of real-life attacks on women that were reported in Paris parking garages. Filming began in late-2006 in Toronto, with the majority of the shoot taking place in a real, operating parking garage.

P2 was released theatrically in the United States in November 2007, and was the first feature film distributed by Summit Entertainment. It received mixed reviews from critics and was a box-office failure domestically, averaging less than $1,000 per cinema during its opening weekend. Despite this, the film went on to gross $7.7 million internationally, becoming an eventual modest success.
