Los Angeles ? A real scary movie bumped off the spoof variety at the box office.

Sony’s fright flick “Silent Hill,” set in an eerie ghost town, debuted with $20.2 million. It took over the top spot from the Weinstein Co. comedy “Scary Movie 4,” which slipped to No. 2 with $17 million in its second weekend, according to studio estimates Sunday.

The White House assassination tale “The Sentinel,” a 20th Century Fox thriller starring Michael Douglas, Kiefer Sutherland and Eva Longoria, opened in third place with $14.65 million.

The weekend’s other new major debut, Universal’s George W. Bush-“American Idol” parody “American Dreamz” featuring Dennis Quaid and Hugh Grant, debuted a weak No. 8 with $3.7 million.

After two weekends in limited release, Jennifer Aniston’s comic drama “Friends With Money” expanded nationwide and came in at No. 10 with $3.55 million. Aniston plays a down-on-her-luck housecleaner with three well-to-do pals (Frances McDormand, Catherine Keener and Joan Cusack).

Lifted by box-office leaders that included 20th Century Fox’s animated hit “Ice Age: The Meltdown” at No. 4 with $12.8 million, Hollywood revenues rose for the fifth straight weekend. The top 12 movies took in $100.4 million, up 22 percent from the same weekend last year.

After a prolonged dry spell in 2005, when movie attendance fell 8 percent, Hollywood is on solid footing this year heading into a potentially big summer. A surge over the past month has attendance running 4 percent ahead of last year’s, said Paul Dergarabedian, president of box-office tracker Exhibitor Relations.
