Horror movie “Paranormal Activity 3” jolted awake a sleepy movie box office with an estimated $80m (£50.2m) in global ticket sales over the weekend. The third instalment of the low-budget haunted house movies topped domestic charts with $54m from US and Canadian theatres, the highest-grossing domestic debut for a horror film and a record for an October release. The movie added $26m from international markets including Britain over the weekend, distributor Paramount Pictures said yesterday. Like the first two films in the series, "Paranormal 3" was released just before Halloween and produced on a budget tiny by Hollywood standards. The latest movie, the most expensive of the trio, cost $5m to make. The movie is a prequel about two young sisters and their creepy encounters with an invisible presence in their home, all recorded by surveillance cameras.
