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.

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.

Based on the MTV show that featured Knoxville and his gang doing reckless stunts and dares, "Jackass Number Two" outstripped the opening weekend of 2002's "Jackass," which debuted with $22.8 million.

Warner Independent's whimsical fantasy "The Science of Sleep" opened strongly in limited release with $347,000 in 14 theaters.

1. "Jackass Number Two," $28.1 million.

2. "Jet Li's Fearless," $10.6 million.

3. "Gridiron Gang," $9.7 million.

4. "Flyboys," $6 million.

5. "Everyone's Hero," $4.75 million.
