Los Angeles ? Johnny Knoxville and his pals pulled another prank on Hollywood as their sequel of crazy stunts, “Jackass Number Two,” beat a rush of serious movies to take the top spot at the weekend box office.

Paramount’s “Jackass Number Two” debuted with $28.1 million, with Focus Features’ “Jet Li’s Fearless,” featuring the martial-arts master in a saga set in China a century ago, opening in second place with $10.6 million, according to studio estimates Sunday.

The weekend’s other new wide releases debuted weakly, with MGM’s World War I tale “Flyboys” opening at No. 4 with $6 million and Sean Penn’s political drama “All the King’s Men” from Sony premiering at No. 7 with $3.8 million.

Overall box office receipts declined for the third-straight weekend, the top-12 movies taking in $81.9 million, down 7 percent from the same period last year. That follows a solid summer for Hollywood, whereas movie attendance began picking up this time last year after a prolonged summer slump.
