Scary movie fans are still into Paranormal Activity, though the horror franchise looks as though it's starting to run out of steam at the box office.
Paramount's Paranormal Activity 4 debuted at No. 1 with $30.2 million, a big drop from the $40 million and $50 million opening weekends of the last two installments, according to studio estimates.
Perpetual hit maker Tyler Perry failed to find an audience for his new persona as ace crime solver. Summit Entertainment's Alex Cross, starring Perry as author James Patterson's criminal profiler, was a dud, opening at No. 5 with $11.8 million.
Ben Affleck's Iran hostage tale Argo held up well in its second weekend, remaining at No. 2 with $16.6 million, dropping just 15 per cent from its debut. Liam Neeson's action sequel Taken 2 slipped to fourth-place with $13.4 million.
