Paranormal Activity tops US box office
Thanks to positive word-of-mouth, Paramount Pictures decided to release Paranormal Activity nationwide at the weekend.
The horror film, which reportedly only cost $15,000 (£9,200) to make, took $22 million last weekend, compared to Saw VI's $14.8 million.
Paranormal Activity, which has been compared to The Blair Witch Project because it is shot like a homemade documentary, follows a couple coping with apparitions and supernatural phenomena in their home.
The Saw franchise has its lowest opening weekend. Its previous low was $18.3 million for the original movie, with its subsequent instalments all opening at $30 million or above.
Last week's number one, Where the Wild Things Are fell to number three with $14.4 million.
Other films in the top ten included Law Abiding Citizen, Couple's Retreat, Astro Boy, featuring the voices of Nicolas Cage and Kristen Bell, and Cirque Du Freak: The Vampire's Assistant.
